git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes for SPEAr from Olof Johansson: "These are arriving very late in the release cycle, but there has been a change of maintainers on the SPEAr platform and they have needed a while to get going. The patch count is higher than I would like at this point, but they're all relevant fixes and well-contained in their own platform code. I still think it's suitable 3.5 material and I don't think it should increase the need for a -rc8 since they are so contained." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: SPEAr600: Fix timer interrupt definition in spear600.dtsi ARM: dts: SPEAr320: Boot the board in EXTENDED_MODE ARM: dts: SPEAr320: Fix compatible string Clk: SPEAr1340: Update sys clock parent array clk: SPEAr1340: Fix clk enable register for uart1 and i2c1.

Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to inactive domains') introduced possibility to add devices to inactive power domains and added pm_genpd_dev_need_restore() function which lets platform core to notify power domain core that the specified device must be restored (with its runtime_resume() callback) before first use. This patch adds the pm_genpd_dev_need_restore() call what brings back the suspend/resume behaviour for the client devices known from the previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM: EXYNOS: Hook up power domains to generic power domain infrastructure'). Client device drivers relay on that suspend/resume behaviour, thus this patch fixes runtime pm operation for client devices.

2012-07-09ARM: OMAP2+: omap2plus_defconfig: EHCI driver is not stable, disable itKevin Hilman
The EHCI driver is not stable enough to be enabled by default. In v3.5, it has at least the following problems: - warning dump during bootup - hang during suspend - prevents CORE powerdomain from entering retention during idle (even when no USB devices connected.) This demonstrates that this driver has not been thoroughly tested and therfore should not be enabled in the default defconfig. In addition, the problems above cause new PM regressions which need be addressed before this driver should be enabled in the default defconfig.

When pin control mapping tables are written the registered device name is supplied for use in name-based searches within the pinctrl driver. In the case of the DB8500 the string "pinctrl-db8500" is used. However, when we register the driver with Device Tree, its naming convention uses something that looks more like "pinctrl.2". To work around the device naming inconsistencies between devices registered via platform code and the ones registered by Device Tree, we use AUXDATA to over-ride the Device Tree naming scheme.

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: 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.

2012-07-04ARM: OMAP4: hwmod data: temporarily comment out data for the usb_host_fs and ↵Paul Walmsley
aess IP blocks The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special programming for them to enter idle. Without this programming, they will prevent the rest of the chip from entering full chip idle. To implement the idle programming cleanly, this will take some coordination between maintainers. This is likely to take some time, so it is probably best to leave this for 3.6 or 3.7. So, in the meantime, prevent these IP blocks from being registered. Later, once the appropriate support is available, this patch can be reverted. This second version comments out the IP block data since Benoît didn't like removing it.
