git commit b2bbb20b37d734443d1c279d0033a64f6095db54 added direct support for PXA GPIO D+ pullup as alternative to the older udc_command ops method. This was done by introduction of the pxa2xx_udc_mach_info member "gpio_pullup" which, if initialized, is now used in (almost) all places where udc_command used to be called.

2007-07-12usb gadget stack: remove usb_ep_*_buffer(), part 2David Brownell
This patch removes controller driver infrastructure which supported the now-removed usb_ep_{alloc,free}_buffer() calls. As can be seen, many of the implementations of this were broken to various degrees. Many didn't properly return dma-coherent mappings; those which did so were necessarily ugly because of bogosity in the underlying dma_free_coherent() calls ... which on many platforms can't be called from the same contexts (notably in_irq) from which their dma_alloc_coherent() sibling can be called. The main potential downside of removing this is that gadget drivers wouldn't have specific knowledge that the controller drivers have: endpoints that aren't dma-capable don't need any dma mappings at all.

2007-07-12USB: pxa2xx_udc -- cleanups, mostly removing dma hooksDavid Brownell
Cleanups to the pxa2xx_udc code: - Primarily removing unused DMA hooks. - One "sparse" warning removed - Remove some Lubbock-only LED hooks (for debugging) That DMA code was never really completed. It worked, mostly, for IN transfers (to the host) if they were fortuitously aligned, but that code was never fully tested. And it was never coded for OUT transfers (which is where DMA would really help) ... because of chip errata on essentially every chip other than the pxa255, and because of design botches (nothing automated data toggle). So it's effectively been dead code for several years now ... no point in keeping it around.

2007-04-21[ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXXEric Miao
This patch removes the unnecessary bit number from CKENnn_XXXX definitions for PXA, so that CKEN0_PWM0 --> CKEN_PWM0 CKEN1_PWM1 --> CKEN_PWM1 ... CKEN24_CAMERA --> CKEN_CAMERA The reasons for the change of these defitions are: 1. they do not scale - they are currently valid for pxa2xx, but definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera instead of bit 24 2. they are unnecessary - the peripheral name within the definition has already announced its usage, we don't need those bit numbers to know which peripheral we are going to enable/disable clock for 3. they are inconvenient - think about this: a driver programmer for pxa has to remember which bit in the CKEN register to turn on/off Another change in the patch is to make the definitions equal to its clock bit index, so that #define CKEN_CAMERA (24) instead of #define CKEN_CAMERA (1 << 24) this change, however, will add a run-time bit shift operation in pxa_set_cken(), but the benefit of this change is that it scales when bit index exceeds 32, e.g., pxa3xx has two registers CKENA and CKENB, totally 64 bit for this, suppose CAMERA clock enabling bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10) and so that pxa_set_cken() need minimum change to adapt to that.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-08[ARM] 4141/1: consolidate functions that handles gpio in pxa2xx_udcMilan Svoboda
This patch renames pxa_gpio_set/get functions defined in drivers/usb/gadget/pxa2xx_udc.h to udc_gpio_set/get. These functions are moved from drivers/usb/gadget/pxa2xx_udc.h to include/asm-arm/arch-pxa2xx/udc.h Creates new functions: udc_gpio_to_irq, udc_gpio_init_vbus, udc_gpio_init_pullup in include/asm-arm/arch-pxa2xx/udc.h. These functions are used in drivers/usb/gadget/pxa2xx_udc.c instead of direct low-level (pxa2xx only) functions. Creates all these udc_gpio_* functions in include/asm-arm/arch-ixp4xx/udc.h. This implementation has no real code because ixp4xx doesn't use vbus - only vbus uses all these gpio functions (and because ixp4xx misses any function which converts number of gpio pin into it's irq). This is next step to make pxa2xx_udc fully work on ixp4xx platform. Signed-off-by: Milan Svoboda <msvoboda@ra.rockwell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2006-09-27USB: pxa2xx_udc understands GPIO based VBUS sensingDavid Brownell
This updates the PXA 25x UDC board-independent infrastructure for VBUS sensing and the D+ pullup. The original code evolved from rather bizarre support on Intel's "Lubbock" reference hardware, so that on more sensible hardware it doesn't work as well as it could/should. The change is just to teach the UDC driver how to use built-in PXA GPIO pins directly. This reduces the amount of board-specfic object code needed, and enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one. With VBUS sensing, the UDC is unclocked until a host is actually connected. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

I think there was a bug in drivers/usb/gadget/inode.c because it used sizeof(*data) for the kmalloc() and sizeof(data) for the memset(), since sizeof(data) just returns the size for a pointer.

This allows us to eliminate the casts in the drivers, and eventually remove the use of the device_driver function pointer methods for platform device drivers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

2005-10-28[ARM] 3044/1: Fix sparse warnings about incompatible pointer types for ↵Ian Campbell
register defined in pxa-regs.h Patch from Ian Campbell The sparse warning initially surfaced in sound/arm/pxa2xx-ac97.c because it was using u32 * variables to hold the unsigned long * register addresses. I submitted an ALSA patch for this http://thread.gmane.org/gmane.linux.alsa.devel/27804 issue and it was suggested that it might be preferable to change the register definitions to use u32. Most other subarches seem to use u32 for their register type, at least the ones which use a __REG macro (like the PXA) do. Nico indicated in the thread above that he wouldn't mind this patch. Changing the type required fixes for opposite warnings in the pxa2xx usb gadget code but that was the only new warning introduced on defconfig or lubbock, mainstone and our own PXA255 boards.
