Device Tree makes it possible +to support many hardware configurations with a single kernel and without the +need to explicitly load or blacklist kernel modules. Note that this isn't a +"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices +are still configured by the board support code, but the intention is to +eventually reach that goal. + +On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By +default, the Raspberry Pi kernel boots with device tree enabled. You can +completely disable DT usage (for now) by adding: + + device_tree= + +to your config.txt, which should cause your Pi to revert to the old way of +doing things after a reboot. + +In /boot you will find a .dtb for each base platform. This describes the +hardware that is part of the Raspberry Pi board. The loader (start.elf and its +siblings) selects the .dtb file appropriate for the platform by name, and reads +it into memory. At this point, all of the optional interfaces (i2c, i2s, spi) +are disabled, but they can be enabled using Device Tree parameters: + + dtparam=i2c=on,i2s=on,spi=on + +However, this shouldn't be necessary in many use cases because loading an +overlay that requires one of those interfaces will cause it to be enabled +automatically, and it is advisable to only enable interfaces if they are +needed. + +Configuring additional, optional hardware is done using Device Tree overlays +(see below). + +raspi-config +============ + +The Advanced Options section of the raspi-config utility can enable and disable +Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it +is possible to both enable an interface and blacklist the driver, if for some +reason you should want to defer the loading. + +Modules +======= + +As well as describing the hardware, Device Tree also gives enough information +to allow suitable driver modules to be located and loaded, with the corollary +that unneeded modules are not loaded. As a result it should be possible to +remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can +have its contents deleted (or commented out). + +Using Overlays +============== + +Overlays are loaded using the "dtoverlay" directive. As an example, consider the +popular lirc-rpi module, the Linux Infrared Remote Control driver. In the +pre-DT world this would be loaded from /etc/modules, with an explicit +"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled, +this becomes a line in config.txt: + + dtoverlay=lirc-rpi + +This causes the file /boot/overlays/lirc-rpi-overlay.dtb to be loaded. By +default it will use GPIOs 17 (out) and 18 (in), but this can be modified using +DT parameters: + + dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13 + +Parameters always have default values, although in some cases (e.g. "w1-gpio") +it is necessary to provided multiple overlays in order to get the desired +behaviour.

We notify the +** suspend completion and reset the resume state machine. +** +** VC_RESUME_IDLE - Initialise the resume completion at the same time. The +** resume completion is in it's 'done' state whenever +** videcore is running. Therfore, the VC_RESUME_IDLE state +** implies that videocore is suspended. +** Hence, any thread which needs to wait until videocore is +** running can wait on this completion - it will only block +** if videocore is suspended. +** +** VC_RESUME_RESUMED - Resume has completed successfully.

In addition + * to providing an example of a genuinely useful gadget driver for a USB + * device, it also illustrates a technique of double-buffering for increased + * throughput. Last but not least, it gives an easy way to probe the + * behavior of the Mass Storage drivers in a USB host. + * + * Backing storage is provided by a regular file or a block device, specified + * by the "file" module parameter. Access can be limited to read-only by + * setting the optional "ro" module parameter. (For CD-ROM emulation, + * access is always read-only.) The gadget will indicate that it has + * removable media if the optional "removable" module parameter is set. + * + * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI), + * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected + * by the optional "transport" module parameter. It also supports the + * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03), + * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by + * the optional "protocol" module parameter. In addition, the default + * Vendor ID, Product ID, release number and serial number can be overridden. + * + * There is support for multiple logical units (LUNs), each of which has + * its own backing file. The number of LUNs can be set using the optional + * "luns" module parameter (anywhere from 1 to 8), and the corresponding + * files are specified using comma-separated lists for "file" and "ro". + * The default number of LUNs is taken from the number of "file" elements; + * it is 1 if "file" is not given. If "removable" is not set then a backing + * file must be specified for each LUN. If it is set, then an unspecified + * or empty backing filename means the LUN's medium is not loaded. Ideally + * each LUN would be settable independently as a disk drive or a CD-ROM + * drive, but currently all LUNs have to be the same type. The CD-ROM + * emulation includes a single data track and no audio tracks; hence there + * need be only one backing file per LUN. + * + * Requirements are modest; only a bulk-in and a bulk-out endpoint are + * needed (an interrupt-out endpoint is also needed for CBI). The memory + * requirement amounts to two 16K buffers, size configurable by a parameter. + * Support is included for both full-speed and high-speed operation. + * + * Note that the driver is slightly non-portable in that it assumes a + * single memory/DMA buffer will be useable for bulk-in, bulk-out, and + * interrupt-in endpoints. With most device controllers this isn't an + * issue, but there may be some with hardware restrictions that prevent + * a buffer from being used by more than one endpoint. + * + * Module options: + * + * file=filename[,filename...] + * Required if "removable" is not set, names of + * the files or block devices used for + * backing storage + * serial=HHHH... Required serial number (string of hex chars) + * ro=b[,b...] Default false, booleans for read-only access + * removable Default false, boolean for removable media + * luns=N Default N = number of filenames, number of + * LUNs to support + * nofua=b[,b...] Default false, booleans for ignore FUA flag + * in SCSI WRITE(10,12) commands + * stall Default determined according to the type of + * USB device controller (usually true), + * boolean to permit the driver to halt + * bulk endpoints + * cdrom Default false, boolean for whether to emulate + * a CD-ROM drive + * transport=XXX Default BBB, transport name (CB, CBI, or BBB) + * protocol=YYY Default SCSI, protocol name (RBC, 8020 or + * ATAPI, QIC, UFI, 8070, or SCSI; + * also 1 - 6) + * vendor=0xVVVV Default 0x0525 (NetChip), USB Vendor ID + * product=0xPPPP Default 0xa4a5 (FSG), USB Product ID + * release=0xRRRR Override the USB release number (bcdDevice) + * buflen=N Default N=16384, buffer size used (will be + * rounded down to a multiple of + * PAGE_CACHE_SIZE) + * + * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro", + * "removable", "luns", "nofua", "stall", and "cdrom" options are available; + * default values are used for everything else. + * + * The pathnames of the backing files and the ro settings are available in + * the attribute files "file", "nofua", and "ro" in the lun subdirectory of + * the gadget's sysfs directory. If the "removable" option is set, writing to + * these files will simulate ejecting/loading the medium (writing an empty + * line means eject) and adjusting a write-enable tab. Changes to the ro + * setting are not allowed when the medium is loaded or if CD-ROM emulation + * is being used. + * + * This gadget driver is heavily based on "Gadget Zero" by David Brownell. + * The driver's SCSI command interface was based on the "Information + * technology - Small Computer System Interface - 2" document from + * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at + * . The single exception + * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the + * "Universal Serial Bus Mass Storage Class UFI Command Specification" + * document, Revision 1.0, December 14, 1998, available at + * . + */ + + +/* + * Driver Design + * + * The FSG driver is fairly straightforward. There is a main kernel + * thread that handles most of the work. Interrupt routines field + * callbacks from the controller driver: bulk- and interrupt-request + * completion notifications, endpoint-0 events, and disconnect events. + * Completion events are passed to the main thread by wakeup calls. Many + * ep0 requests are handled at interrupt time, but SetInterface, + * SetConfiguration, and device reset requests are forwarded to the + * thread in the form of "exceptions" using SIGUSR1 signals (since they + * should interrupt any ongoing file I/O operations). + * + * The thread's main routine implements the standard command/data/status + * parts of a SCSI interaction. It and its subroutines are full of tests + * for pending signals/exceptions -- all this polling is necessary since + * the kernel has no setjmp/longjmp equivalents. (Maybe this is an + * indication that the driver really wants to be running in userspace.) + * An important point is that so long as the thread is alive it keeps an + * open reference to the backing file. This will prevent unmounting + * the backing file's underlying filesystem and could cause problems + * during system shutdown, for example. To prevent such problems, the + * thread catches INT, TERM, and KILL signals and converts them into + * an EXIT exception. + * + * In normal operation the main thread is started during the gadget's + * fsg_bind() callback and stopped during fsg_unbind(). But it can also + * exit when it receives a signal, and there's no point leaving the + * gadget running when the thread is dead. So just before the thread + * exits, it deregisters the gadget driver. This makes things a little + * tricky: The driver is deregistered at two places, and the exiting + * thread can indirectly call fsg_unbind() which in turn can tell the + * thread to exit. The first problem is resolved through the use of the + * REGISTERED atomic bitflag; the driver will only be deregistered once. + * The second problem is resolved by having fsg_unbind() check + * fsg->state; it won't try to stop the thread if the state is already + * FSG_STATE_TERMINATED. + * + * To provide maximum throughput, the driver uses a circular pipeline of + * buffer heads (struct fsg_buffhd). In principle the pipeline can be + * arbitrarily long; in practice the benefits don't justify having more + * than 2 stages (i.e., double buffering). But it helps to think of the + * pipeline as being a long one. Each buffer head contains a bulk-in and + * a bulk-out request pointer (since the buffer can be used for both + * output and input -- directions always are given from the host's + * point of view) as well as a pointer to the buffer and various state + * variables. + * + * Use of the pipeline follows a simple protocol. There is a variable + * (fsg->next_buffhd_to_fill) that points to the next buffer head to use. + * At any time that buffer head may still be in use from an earlier + * request, so each buffer head has a state variable indicating whether + * it is EMPTY, FULL, or BUSY. Typical use involves waiting for the + * buffer head to be EMPTY, filling the buffer either by file I/O or by + * USB I/O (during which the buffer head is BUSY), and marking the buffer + * head FULL when the I/O is complete. Then the buffer will be emptied + * (again possibly by USB I/O, during which it is marked BUSY) and + * finally marked EMPTY again (possibly by a completion routine). + * + * A module parameter tells the driver to avoid stalling the bulk + * endpoints wherever the transport specification allows. This is + * necessary for some UDCs like the SuperH, which cannot reliably clear a + * halt on a bulk endpoint. However, under certain circumstances the + * Bulk-only specification requires a stall. In such cases the driver + * will halt the endpoint and set a flag indicating that it should clear + * the halt in software during the next device reset. Hopefully this + * will permit everything to work correctly. Furthermore, although the + * specification allows the bulk-out endpoint to halt when the host sends + * too much data, implementing this would cause an unavoidable race. + * The driver will always use the "no-stall" approach for OUT transfers. + * + * One subtle point concerns sending status-stage responses for ep0 + * requests. Some of these requests, such as device reset, can involve + * interrupting an ongoing file I/O operation, which might take an + * arbitrarily long time. During that delay the host might give up on + * the original ep0 request and issue a new one. When that happens the + * driver should not notify the host about completion of the original + * request, as the host will no longer be waiting for it. So the driver + * assigns to each ep0 request a unique tag, and it keeps track of the + * tag value of the request associated with a long-running exception + * (device-reset, interface-change, or configuration-change). When the + * exception handler is finished, the status-stage response is submitted + * only if the current ep0 request tag is equal to the exception request + * tag. Thus only the most recently received ep0 request will get a + * status-stage response. + * + * Warning: This driver source file is too long. It ought to be split up + * into a header file plus about 3 separate .c files, to handle the details + * of the Gadget, USB Mass Storage, and SCSI protocols. + */ + + +/* #define VERBOSE_DEBUG */ +/* #define DUMP_MSGS */ + + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +#include +#include + +#include "gadget_chips.h" + + + +/* + * Kbuild is not very cooperative with respect to linking separately + * compiled library objects into one module.

The IO context struct should live in an os-dependent struct +in your driver. As an example, the dwc_usb3 driver has an os-dependent struct +named 'os_dep' embedded in the main device struct.

Since Linux does not +require an IO context, its macros for dwc_read_reg32() and friends do not +use the context pointer, so it is optimized away by the compiler. But it is +necessary to add the pointer parameter to all of the call sites, to be ready +for any future ports (such as FreeBSD) which do require an IO context. + + +Similarly, dwc_alloc(), dwc_alloc_atomic(), dwc_strdup(), and dwc_free() now +take an additional parameter, a pointer to a memory context. Examples: + + addr = dwc_alloc(&usb3_dev->os_dep.memctx, size); + + dwc_free(&usb3_dev->os_dep.memctx, addr); + +Again, for the Linux ports, it is not necessary to actually define the memctx +member, but it is necessary to add the pointer parameter to all of the call +sites. + + +Same for dwc_dma_alloc() and dwc_dma_free().

The WUDEV + * driver uses only these functions. In order to port the WUDEV driver, only + * the functions in this library need to be re-implemented, with the same + * behavior as documented here. + * + * The Common library consists of higher level functions, which rely only on + * calling the functions from the DWC Portability library. These common + * routines are shared across modules. Some of the common libraries need to be + * used directly by the driver programmer when porting WUDEV. Such as the + * parameter and notification libraries. + * + * @section low Portability Library OS Wrapper Functions + * + * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that + * needs to be implemented when porting, for example DWC_MUTEX_ALLOC(). All of + * these functions are included in the dwc_os.h file. + * + * There are many functions here covering a wide array of OS services. Please + * see dwc_os.h for details, and implementation notes for each function. + * + * @section common Common Library Functions + * + * Any function starting with dwc and in all lowercase is a common library + * routine. These functions have a portable implementation and do not need to + * be reimplemented when porting. The common routines can be used by any + * driver, and some must be used by the end user to control the drivers. For + * example, you must use the Parameter common library in order to set the + * parameters in the WUDEV module. + * + * The common libraries consist of the following: + * + * - Connection Contexts - Used internally and can be used by end-user. See dwc_cc.h + * - Parameters - Used internally and can be used by end-user. See dwc_params.h + * - Notifications - Used internally and can be used by end-user. See dwc_notifier.h + * - Lists - Used internally and can be used by end-user. See dwc_list.h + * - Memory Debugging - Used internally and can be used by end-user. See dwc_os.h + * - Modpow - Used internally only. See dwc_modpow.h + * - DH - Used internally only. See dwc_dh.h + * - Crypto - Used internally only. See dwc_crypto.h + * + * + * @section prereq Prerequistes For dwc_os.h + * @subsection types Data Types + * + * The dwc_os.h file assumes that several low-level data types are pre defined for the + * compilation environment. These data types are: + * + * - uint8_t - unsigned 8-bit data type + * - int8_t - signed 8-bit data type + * - uint16_t - unsigned 16-bit data type + * - int16_t - signed 16-bit data type + * - uint32_t - unsigned 32-bit data type + * - int32_t - signed 32-bit data type + * - uint64_t - unsigned 64-bit data type + * - int64_t - signed 64-bit data type + * + * Ensure that these are defined before using dwc_os.h. The easiest way to do + * that is to modify the top of the file to include the appropriate header. + * This is already done for the Linux environment. If the DWC_LINUX macro is + * defined, the correct header will be added. A standard header is + * also used for environments where standard C headers are available. + * + * @subsection stdarg Variable Arguments + * + * Variable arguments are provided by a standard C header . it is + * available in Both the Linux and ANSI C enviornment. An equivalent must be + * provided in your enviornment in order to use dwc_os.h with the debug and + * tracing message functionality. + * + * @subsection thread Threading + * + * WUDEV Core must be run on an operating system that provides for multiple + * threads/processes. Threading can be implemented in many ways, even in + * embedded systems without an operating system. At the bare minimum, the + * system should be able to start any number of processes at any time to handle + * special work. It need not be a pre-emptive system. Process context can + * change upon a call to a blocking function. The hardware interrupt context + * that calls the module's ISR() function must be differentiable from process + * context, even if your processes are impemented via a hardware interrupt. + * Further locking mechanism between process must exist (or be implemented), and + * process context must have a way to disable interrupts for a period of time to + * lock them out. If all of this exists, the functions in dwc_os.h related to + * threading should be able to be implemented with the defined behavior. + * + */ + +#ifdef __cplusplus +} +#endif + +#endif /* _DWC_OS_H_ */ diff -Nur '--exclude=.git' linux-stable/drivers/usb/host/dwc_common_port/Makefile raspilinux/drivers/usb/host/dwc_common_port/Makefile --- linux-stable/drivers/usb/host/dwc_common_port/Makefile 1970-01-01 01:00:00.000000000 +0100 +++ raspilinux/drivers/usb/host/dwc_common_port/Makefile 2015-12-26 19:08:32.724519423 +0100 @@ -0,0 +1,58 @@ +# +# Makefile for DWC_common library +# + +ifneq ($(KERNELRELEASE),) + +ccflags-y += -DDWC_LINUX +#ccflags-y += -DDEBUG +#ccflags-y += -DDWC_DEBUG_REGS +#ccflags-y += -DDWC_DEBUG_MEMORY + +ccflags-y += -DDWC_LIBMODULE +ccflags-y += -DDWC_CCLIB +#ccflags-y += -DDWC_CRYPTOLIB +ccflags-y += -DDWC_NOTIFYLIB +ccflags-y += -DDWC_UTFLIB + +obj-$(CONFIG_USB_DWCOTG) += dwc_common_port_lib.o +dwc_common_port_lib-objs := dwc_cc.o dwc_modpow.o dwc_dh.o \ + dwc_crypto.o dwc_notifier.o \ + dwc_common_linux.o dwc_mem.o + +kernrelwd := $(subst ., ,$(KERNELRELEASE)) +kernrel3 := $(word 1,$(kernrelwd)).$(word 2,$(kernrelwd)).$(word 3,$(kernrelwd)) + +ifneq ($(kernrel3),2.6.20) +# grayg - I only know that we use ccflags-y in 2.6.31 actually +ccflags-y += $(CPPFLAGS) +endif + +else + +#ifeq ($(KDIR),) +#$(error Must give "KDIR=/path/to/kernel/source" on command line or in environment) +#endif + +ifeq ($(ARCH),) +$(error Must give "ARCH=" on command line or in environment.
