ARM: pxa: move clk register definitions to driver The clock register definitions are now used (almost) exclusively in the clk driver, and that relies on no other mach/*.h header files any more. Remove the dependency on mach/pxa*-regs.h by addressing the registers as offsets from a void __iomem * pointer, which is either passed from a board file, or (for the moment) ioremapped at boot time from a hardcoded address in case of DT (this should be moved into the DT of course).

ARM: pxa: split up mach/hardware.h The mach/hardware.h is included in lots of places, and it provides three different things on pxa: - the cpu_is_pxa* macros - an indirect inclusion of mach/addr-map.h - the __REG() and io_pv2() helper macros Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h headers, then change all the files that use mach/hardware.h to include the exact set of those three headers that they actually need, allowing for further more targeted cleanup. linux/soc/pxa/cpu.h can remain permanently exported and is now in a global location along with similar headers. pxa-regs.h and addr-map.h are only used in a very small number of drivers now and can be moved to arch/arm/mach-pxa/ directly when those drivers are to pass the necessary data as resources.

ARM: pxa: change clocks init sequence Since pxa clocks were ported to the clock framework, an ordering issue appears between clocks and clocksource initialization. As a consequence, the pxa timer clock cannot be acquired in pxa_timer, and is disabled by clock framework because it is "unused". The ordering issue is that in the kernel boot sequence : start_kernel() ... time_init() -> pxa_timer() -> here the clocksource is initialized ... rest_init() kernel_init() initcalls -> here the clocks are initialized In the current sequence, the clocks are initialized way after pxa_timer, which cannot acquire the OSTIMER0 clock. To solve this issue, the clocks initialization is moved to pxa_timer(), so that clocks are initialized before clocksource for non device-tree. For device-tree, the standard arm time_init() will take care of the ordering. Reviewed-by: Michael Turquette <mturquette@linaro.org> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

[ARM] 4711/1: pxa: mmc: move DMA specific code to platform layer This patch is to move pxamci DMA specific code to corresponding platform layer because using DRCMRRXMMC/DRCMRTXMMC in pxamci.c makes the driver code dedicated to platform which is not extensible. It is applicable to all pxa platforms. Signed-off-by: Bridge Wu <bridge.wu@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put() pxa_gpio_mode() is a universal call that fiddles with the GAFR (gpio alternate function register.) GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] 4559/1: pxa: make PXA_LAST_GPIO a run-time variable This definition produces processor specific code in generic function pxa_gpio_mode(), thus creating inconsistencies for support of pxa25x and pxa27x in a single zImage. As David Brownell suggests, make it a run-time variable and initialize at run-time according to the number of GPIOs on the processor. For now the initialization happens in pxa_init_irq_gpio(), since there is already a parameter for that, besides, this is and MUST be earlier than any subsequent calls to pxa_gpio_mode().

[ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXX 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.

[ARM] 3848/1: pxafb: Add option of fixing video modes and spitz QVGA mode support Add the ability to have pxafb use only certain fixed video modes (selected on a per platform basis). This is useful on production hardware such as the Zaurus cxx00 models where the valid modes are known in advance and any other modes could result in hardware damage. Following this, add support for the cxx00 QVGA mode. Mode information is passed to the lcd_power call to allowing the panel drivers to configure the display hardware accordingly (corgi_lcd already contains the functionality for the cxx00 panel). This mirrors the setup already used by w100fb. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[PATCH] fix missing includes I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
