2012-07-06ARM: mach-shmobile: select the fixed regulator driver on several boardsGuennadi Liakhovetski
On systems, using regulators to supply power to devices, if the REGULATOR Kconfig option is disabled, regulator API stubs will be used, which often suffices to bring a default configuration up. If REGULATOR is enabled but respective regulator drivers are inactive, the real regulator API calls will be used, which in the absence of drivers will fail to provide services. This patch prevents such a problem on sh-mobile boards by forcing REGULATOR_FIXED_VOLTAGE on if REGULATOR is selected.

2012-07-06ARM: OMAP3530evm: set pendown_state and debounce time for ads7846Zumeng Chen
Currently most ads7846 config definitions for OMAP3 series boards have been moved to common-board-devices.c, and it is transparent for init. And it's no very proper to do gpio_request based on get_pendown_state since omap_ads7846_init knows everything about ads7846_config. So it's more fit to request gpio according to the right gpio_pendown and set debounce time conditionally. If we don't set proper debouce time, there are flooded interrupt counters of ads7846 responding to one time touch on screen, then the driver couldn't work very well.

2012-07-05ARM: OMAP2+: hwmod code/clockdomain data: fix 32K sync timerPaul Walmsley
Kevin discovered that commit c8d82ff68fb6873691536cf33021977efbf5593c ("ARM: OMAP2/3: hwmod data: Add 32k-sync timer data to hwmod database") broke CORE idle on OMAP3. This prevents device low power states. The root cause is that the 32K sync timer IP block does not support smart-idle mode[1], and so the hwmod code keeps the IP block in no-idle mode while it is active. This in turn prevents the WKUP clockdomain from transitioning to idle. There is a hardcoded sleep dependency that prevents the CORE_L3 and CORE_CM clockdomains from transitioning to idle when the WKUP clockdomain is active[2], so the chip cannot enter any device low power states. It turns out that there is no need to take the 32k sync timer out of idle. The IP block itself probably does not have any native idle handling at all, due to its simplicity. Furthermore, the PRCM will never request target idle for this IP block while the kernel is running, due to the sleep dependency that prevents the WKUP clockdomain from idling while the CORE_L3 clockdomain is active. So we can safely leave the 32k sync timer in target-force-idle mode, even while we continue to access it. This workaround is implemented by defining a new clockdomain flag, CLKDM_ACTIVE_WITH_MPU, that indicates that the clockdomain is guaranteed to be active whenever the MPU is inactive. If an IP block's main functional clock exists inside this clockdomain, and the IP block does not support smart-idle modes, then the hwmod code will place the IP block into target force-idle mode even when enabled. The WKUP clockdomains on OMAP3/4 are marked with this flag. (On OMAP2xxx, no OCP header existed on the 32k sync timer.) Other clockdomains also should be marked with this flag, but those changes are deferred until a later merge window, to create a minimal fix. Another theoretically clean fix for this problem would be to implement PM runtime-based control for 32k sync timer accesses. These PM runtime calls would need to located in a custom clocksource, since the 32k sync timer is currently used as an MMIO clocksource. But in practice, there would be little benefit to doing so; and there would be some cost, due to the addition of unnecessary lines of code and the additional CPU overhead of the PM runtime and hwmod code - unnecessary in this case. Another possible fix would have been to modify the pm34xx.c code to force the IP block idle before entering WFI. But this would not have been an acceptable approach: we are trying to remove this type of centralized IP block idle control from the PM code.

2012-07-05ARM: OMAP2+: am33xx: Make am33xx as a separate classVaibhav Hiremath
Initially, we decided to make am33xx family of device to fall under omap3 class (cpu_is_omap34xx() = true), since it carries Cortex-A8 core. But while adding complete baseport support (like, clock, power and hwmod) support, it is observed that, we are creating more and more problems by treating am33xx device as omap3 family, as nothing matches between them (except cortex-A8 mpu). So, after long discussion we have came to the conclusion that, we should not consider am33xx device as omap3 family, instead create separate class (SOC_AM33XX) under OMAP2PLUS. This means, for am33xx device, cpu_is_omap34xx() will return false, and only cpu_is_am33xx() will be true.

2012-07-05ARM: 7441/1: perf: return -EOPNOTSUPP if requested mode exclusion is unavailableWill Deacon
We currently return -EPERM if the user requests mode exclusion that is not supported by the CPU. This looks pretty confusing from userspace and is inconsistent with other architectures (ppc, x86). This patch returns -EOPNOTSUPP instead. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-07-05ARM: 7443/1: Revert "new way of handling ERESTART_RESTARTBLOCK"Will Deacon
This reverts commit 6b5c8045ecc7e726cdaa2a9d9c8e5008050e1252. Conflicts: arch/arm/kernel/ptrace.c The new syscall restarting code can lead to problems if we take an interrupt in userspace just before restarting the svc instruction. If a signal is delivered when returning from the interrupt, the TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed from the signal handler to be treated as a restart of the previously interrupted system call. This includes the final sigreturn call, meaning that we may fail to exit from the signal context. Furthermore, if a system call made from the signal handler requires a restart via the restart_block, it is possible to clear the thread flag and fail to restart the originally interrupted system call. The right solution to this problem is to perform the restarting in the kernel, avoiding the possibility of handling a further signal before the restart is complete. Since we're almost at -rc6, let's revert the new method for now and aim for in-kernel restarting at a later date.

2012-07-05ARM: 7442/1: Revert "remove unused restart trampoline"Will Deacon
This reverts commit fa18484d0947b976a769d15c83c50617493c81c1. We need the restart trampoline back so that we can revert a related problematic patch 6b5c8045ecc7e726cdaa2a9d9c8e5008050e1252 ("arm: new way of handling ERESTART_RESTARTBLOCK").
