* ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+Tony Lindgren2012-09-131-4/+281
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

* ARM: OMAP: Move gpio.h to include/linux/platform_dataTony Lindgren2012-09-138-2/+7
| | | | | | | | | | | | | | | | | This way we can remove includes of plat/gpio.h which won't work with the single zImage support. Note that we also remove the cpu_class_is_omap2() check in gpio-omap.c as the drivers should not call it as we need to make it local to arch/arm/mach-omap2 for single zImage support. While at it, arrange the related includes in the standard way.

Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | The platform data variable loses_context is used to determine if the timer may lose its logic state during power transitions and so needs to be restored. This information is also provided in the HWMOD device attributes for OMAP2+ devices via the OMAP_TIMER_ALWON flag. When this flag is set the timer will not lose context. So use the HWMOD device attributes to determine this. For OMAP1 devices, loses_context is never set and so set the OMAP_TIMER_ALWON flag for OMAP1 timers to ensure that code is equivalent.

The 32KHz sync-timer and a gptimer which can run on 32KHz or system clock (e.g 38.4 MHz). So there can be 3 options - 1. 32KHz sync-timer 2. Sys_clock based (e.g 13/19.2/26/38.4 MHz) gptimer 3. 32KHz based gptimer. The optional gptimer based clocksource was added so that it can give the high precision than sync-timer, so expected usage was 2 and not 3. Unfortunately option 2, clocksource doesn't meet the requirement of free-running clock as per clocksource need. It stops in low power states when sys_clock is cut. That makes gptimer based clocksource option useless for OMAP2/3/4 devices with sys_clock as a clock input. So, in order to use option 2, deeper idle state MUST be disabled. Option 3 will still work but it is no better than 32K sync-timer based clocksource. We must support both sync timer and gptimer based clocksource as some OMAP based derivative SoCs like AM33XX does not have the sync timer. Considering above, make sync-timer and gptimer clocksource runtime selectable so that both OMAP and AMXXXX continue to use the same code. And, in order to precisely configure/setup sched_clock for given clocksource, decision has to be made early enough in boot sequence. So, the solution is, Use standard kernel parameter ("clocksource=") to override default 32k_sync-timer, in addition to this, we also use hwmod database lookup mechanism, through which at run-time we can identify availability of 32k-sync timer on the device, else fall back to gptimer.

This patch adds check for return value from function omap_init_clocksource_32k(), and fallback to omap_mpu_timer_init() in case of failure/error from omap_init_clocksource_32k().

Previously, the driver was simply calling a symbol defined in the OMAP platform code, but this is incorrect: drivers should be fully decoupled from platform and architecture code. So instead, modify the driver to call through a platform_data function pointer instead. We skip any DT aspect, since OMAP1 is not scheduled to be converted to DT in the near future. This resolves the following sparse warning: It also gets rid of a cpu_is_omap16xx() call in a driver. In the long term, it probably makes sense to move the OCPI bus code to somewhere under drivers/. This should avoid the whole platform_data/DT issue with this function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the OMAP1 OCPI "bus" code to arch/arm/mach-omap1, since it is only used on OMAP1 devices. In the long term, it probably makes sense to move the OCPI bus code to somewhere under drivers/. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Tony Lindgren <tony@atomide.com>

* | / ARM: OMAP1: Amstrad Delta: Fix wrong IRQ base in FIQ handlerJanusz Krzysztofik2012-05-041-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 384ebe1c2849160d040df3e68634ec506f13d9ff, "gpio/omap: Add DT support to GPIO driver", introduced dynamic IRQ numbering of OMAP GPIO interrupts, breaking all IH_GPIO_BASE based IRQ number calculations. This issue was corrected in the OMAP GPIO driver and the related header file with commit 25db711df3258d125dc1209800317e5c0ef3c870, "gpio/omap: Fix IRQ handling for SPARSE_IRQ". However, the Amstrad Delta FIQ handler, which replaces the gpio-omap driver in serving GPIO interrupts on this board, still uses that outdated method. Fix it.

* | ARM: OMAP1: DMTIMER: fix broken timer clock source selectionPaul Walmsley2012-04-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DMTIMER source selection on OMAP1 is broken. omap1_dm_timer_set_src() tries to use __raw_{read,write}l() to read from and write to physical addresses, but those functions take virtual addresses. sparse caught this: arch/arm/mach-omap1/timer.c:50:13: warning: incorrect type in argument 1 (different base types) arch/arm/mach-omap1/timer.c:50:13: expected void const volatile [noderef] <asn:2>*<noident> arch/arm/mach-omap1/timer.c:50:13: got unsigned int arch/arm/mach-omap1/timer.c:52:9: warning: incorrect type in argument 1 (different base types) arch/arm/mach-omap1/timer.c:52:9: expected void const volatile [noderef] <asn:2>*<noident> arch/arm/mach-omap1/timer.c:52:9: got unsigned int Fix by using omap_{read,writel}(), just like the other users of the MOD_CONF_CTRL_1 register in the OMAP1 codebase. Of course, in the long term, removing omap_{read,write}l() is the appropriate thing to do; but this will take some work to do this cleanly. Looks like this was caused by 97933d6 (ARM: OMAP1: dmtimer: conversion to platform devices) that dangerously moved code and changed it in the same patch.

* ARM: fix __io macro for PCMCIARob Herring2012-04-051-0/+45
| | | | | | | | | | | | | | | | | | | | | | With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

| * mtd: maps: physmap: Add reference counter to set_vpp()Paul Parsons2012-03-271-14/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is part of a set which fixes unnecessary flash erase and write errors resulting from the MTD CFI driver turning off vpp while an erase is in progress. This patch allows physmap_set_vpp() calls to be nested by adding a reference counter. omap1_set_vpp() already used a reference counter. Since it is called from physmap_set_vpp(), omap1_set_vpp() can now be simplified. simtec_nor_vpp() already disabled hard interrupts. Since it is called from physmap_set_vpp(), simtec_nor_vpp() can now be simplified.
