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. -+ * -+ */ ---- /dev/null -+++ b/drivers/usb/host/dwc_common_port/usb.h -@@ -0,0 +1,850 @@ -+/* -+ * Copyright (c) 1998 The NetBSD Foundation, Inc. -+ * All rights reserved. -+ * -+ * This code is derived from software contributed to The NetBSD Foundation -+ * by Lennart Augustsson (lennart@augustsson.net) at -+ * Carlstedt Research & Technology. -+ * -+ * Redistribution and use in source and binary forms, with or without -+ * modification, are permitted provided that the following conditions -+ * are met: -+ * 1.

The only exceptions -+ * are creation functions (which might fail due to lack of resources) and functions that -+ * might timeout or fail due to lack of space. Errors that might be reported by the underlying -+ * OS API (e.g. invalid mutex) are treated as a programming error, and are merely asserted on. -+ * -+ * \section thread_synch Threads and synchronisation -+ * -+ * \subsection thread Threads -+ * -+ * The thread API is somewhat different to that found in Nucleus. In particular, threads -+ * cannot just be destroyed at arbitrary times and nor can they merely exit. This is so -+ * that the same API can be implemented across all interesting platforms without too much -+ * difficulty. See vcos_thread.h for details. Thread attributes are configured via -+ * the VCOS_THREAD_ATTR_T structure, found in vcos_thread_attr.h. -+ * -+ * \subsection sema Semaphores -+ * -+ * Counted semaphores (c.f. Nucleus NU_SEMAPHORE) are created with VCOS_SEMAPHORE_T. -+ * Under ThreadX on VideoCore, semaphores are implemented using VideoCore spinlocks, and -+ * so are quite a lot faster than ordinary ThreadX semaphores. See vcos_semaphore.h. -+ * -+ * \subsection mtx Mutexes -+ * -+ * Mutexes are used for locking. Attempts to take a mutex twice, or to unlock it -+ * in a different thread to the one in which it was locked should be expected to fail. -+ * Mutexes are not re-entrant (see vcos_reentrant_mutex.h for a slightly slower -+ * re-entrant mutex). -+ * -+ * \subsection evflags Event flags -+ * -+ * Event flags (the ThreadX name - also known as event groups under Nucleus) provide -+ * 32 flags which can be waited on by multiple clients, and signalled by multiple clients. -+ * A timeout can be specified. See vcos_event_flags.h. An alternative to this is the -+ * VCOS_EVENT_T (see vcos_event.h) which is akin to the Win32 auto-reset event, or a -+ * saturating counted semaphore. -+ * -+ * \subsection event Events -+ * -+ * A VCOS_EVENT_T is a bit like a saturating semaphore. No matter how many times it -+ * is signalled, the waiter will only wake up once. See vcos_event.h. You might think this -+ * is useful if you suspect that the cost of reading the semaphore count (perhaps via a -+ * system call) is expensive on your platform. -+ * -+ * \subsection tls Thread local storage -+ * -+ * Thread local storage is supported using vcos_tls.h. This is emulated on Nucleus -+ * and ThreadX. -+ * -+ * \section int Interrupts -+ * -+ * The legacy LISR/HISR scheme found in Nucleus is supported via the legacy ISR API, -+ * which is also supported on ThreadX. New code should avoid this, and old code should -+ * be migrated away from it, since it is slow. See vcos_legacy_isr.h. -+ * -+ * Registering an interrupt handler, and disabling/restoring interrupts, is handled -+ * using the functions in vcos_isr.h. -+ * -+ */ -+ -+/** -+ * \file vcos.h -+ * -+ * This is the top level header file. Clients include this.
