[PATCH] ARM: imx: Modify IMX_IO_P2V macro

by Robert Lee

A change is needed in the IMX_IO_P2V macro to allow all imx5 platforms to use common definitions when accessing registers of peripherals on the AIPS2 bus. This change was tested for mapping conflicts using the iop2v script found at git://git.pengutronix.de/git/ukl/imx-iop2v.git and by performing a bootup of a default build using imx_v6_v7_defconfig on a imx51 babbage board and imx53 loco board.

[PATCH v3 0/3] Add imx cpuidle

by Robert Lee

Add common imx cpuidle initialization functionality and add a i.MX5 and i.MX6Q platform cpuidle implementation. Based on v3.4-rc6 plus recently submitted device tree late_initcall patch: http://www.spinics.net/lists/arm-kernel/msg171620.html v3 changes: * removed file introduced in v1 no longer needed after v2 [per Shawn Guo] * re-ordered added #includes in alphabetical order [per Shawn Guo] * Remove if(!drv) check to allow handling by stack trace [per Sascha Hauer] * Added missing return value in error meesage [per Shawn Guo] * fixed (void *) casting problem pointed out Sasha Hauer. Used a different type of casting to properly give warning on improper casting: arm_pm_idle = (void (*)(void))imx5_idle; Used this casting instead of adding a dummy caller function because adding the dummy function appears to unnecessarily introduce the following additional operations: static void imx5_pm_idle(void) { a0: e1a0c00d mov ip, sp a4: e92dd800 push {fp, ip, lr, pc} a8: e24cb004 sub fp, ip, #4 imx5_idle(); ac: ebffffd3 bl 0 <imx5_idle> } b0: e89da800 ldm sp, {fp, sp, pc} v2 changes: * Removed some unnecessary spaces [per Jess Juhl] * Added return value for an error message [per Sascha Hauer] * Reworked init scheme to use device tree late_initcall [per Sascha and Shawn] * Moved imx6q and imx5 cpuidle functionality to existing files. https://lkml.org/lkml/2012/5/1/363 v1 initial submission: https://lkml.org/lkml/2012/4/16/644 Robert Lee (3): ARM: imx: Add common imx cpuidle init functionality.

[ANN] Disk upgrade on ci.linaro.org today

by Paul Sokolovsky

Hello, The Infrastructure team works on improving disk layout on Jenkins build systems to avoid common cases of errors which lead to unexpected downtime. We recently migrated android-build.linaro.org to new partition setup, and would like to proceed with ci.linaro.org. This is potentially multi-step process, so we want to start it ASAP to not risk it protruding into release rush time. So, we'd like to schedule a downtime at 14:00 UTC today, expected duration is 1 hr. Please let me know if you have any issues with that time. Thanks, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

[PATCH v3 0/6] thermal: exynos: Add kernel thermal support for exynos platform

by Amit Daniel Kachhap

Hi Andrew, This patchset introduces a new generic cooling device based on cpufreq that can be used on non-ACPI platforms. As a proof of concept, we have drivers for the following platforms using this mechanism now: * TI OMAP (git://git.linaro.org/people/amitdanielk/linux.git omap4460_thermal) * Samsung Exynos (Exynos4 and Exynos5) in the current patchset. * Freescale i.MX (git://git.linaro.org/people/amitdanielk/linux.git imx6q_thermal) These patches have been reviewed by Rui Zhang (https://lkml.org/lkml/2012/4/9/448) who seems to agree with them in principle, but I haven't had any luck getting them merged, perhaps a lack of maintainer bandwidth. ACPI platforms currently have such a mechanism but it is wrapped in ACPI'isms that we don't have on ARM platforms. If this is accepted, I'm proposing to convert over the ACPI thermal driver to use this common code too. Can you please merge these patches for 3.5? Thanks, Amit Daniel Changes since V2: *Added Exynos5 TMU sensor support by enhancing the exynos4 tmu driver. Exynos5 TMU driver was internally developed by SangWook Ju <sw.ju(a)samsung.com>. *Removed cpuhotplug cooling code in this patchset. *Rebased the patches against 3.4-rc6 kernel. Changes since V1: *Moved the sensor driver to driver/thermal folder from driver/hwmon folder as suggested by Mark Brown and Guenter Roeck *Added notifier support to notify the registered drivers of any cpu cooling action. The driver can modify the default cooling behaviour(eg set different max clip frequency). *The percentage based frequency replaced with absolute clipped frequency. *Some more conditional checks when setting max frequency. *Renamed the new trip type THERMAL_TRIP_STATE_ACTIVE to THERMAL_TRIP_STATE_INSTANCE *Many review comments from R, Durgadoss <durgadoss.r(a)intel.com> and eduardo.valentin(a)ti.com implemented. *Removed cooling stats through debugfs patch *The V1 based can be found here, https://lkml.org/lkml/2012/2/22/123 http://lkml.org/lkml/2012/3/3/32 Changes since RFC: *Changed the cpu cooling registration/unregistration API's to instance based *Changed the STATE_ACTIVE trip type to pass correct instance id *Adding support to restore back the policy->max_freq after doing frequency clipping. *Moved the trip cooling stats from sysfs node to debugfs node as suggested by Greg KH greg(a)kroah.com *Incorporated several review comments from eduardo.valentin(a)ti.com *Moved the Temperature sensor driver from driver/hwmon/ to driver/mfd as discussed with Guenter Roeck <guenter.roeck(a)ericsson.com> and Donggeun Kim <dg77.kim(a)samsung.com> (https://lkml.org/lkml/2012/1/5/7) *Some changes according to the changes in common cpu cooling APIs *The RFC based patches can be found here, https://lkml.org/lkml/2011/12/13/186 https://lkml.org/lkml/2011/12/21/169 Brief Description: 1) The generic cooling devices code is placed inside driver/thermal/* as placing inside acpi folder will need un-necessary enabling of acpi code. This codes is architecture independent. 2) This patchset adds a new trip type THERMAL_TRIP_STATE_INSTANCE which passes cooling device instance number and may be helpful for cpufreq cooling devices to take the correct cooling action. This trip type avoids the temperature comparision check again inside the cooling handler. 3) This patchset adds generic cpu cooling low level implementation through frequency clipping and cpu hotplug. In future, other cpu related cooling devices may be added here. An ACPI version of this already exists (drivers/acpi/processor_thermal.c). But this will be useful for platforms like ARM using the generic thermal interface along with the generic cpu cooling devices. The cooling device registration API's return cooling device pointers which can be easily binded with the thermal zone trip points. The important APIs exposed are, a)struct thermal_cooling_device *cpufreq_cooling_register( struct freq_clip_table *tab_ptr, unsigned int tab_size, const struct cpumask *mask_val) b)void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev) 4) Samsung exynos platform thermal implementation is done using the generic cpu cooling APIs and the new trip type. The temperature sensor driver present in the hwmon folder(registered as hwmon driver) is moved to thermal folder and registered as a thermal driver. All this patchset is based on Kernel version 3.4-rc6 A simple data/control flow diagrams is shown below, Core Linux thermal <-----> Exynos thermal interface <----- Temperature Sensor | | \|/ | Cpufreq cooling device <--------------- TODO: *Will send the DT enablement patches later after the driver is merged.

[PATCH 0/2] ARM: OMAP3/4: cpuidle - misc fixes

by Daniel Lezcano

These two patches are coming from the series I previously sent for the cpuidle OMAP3/4 cleanups. The first one, move the powerdomain lookup check in the init function, the second one fix the linkage error, when the CONFIG_PM is not set while CONFIG_CPU_IDLE is. Omap's Kconfig has been modified to select CONFIG_PM when CONFIG_CPU_IDLE is set. I compiled with different options but I was not able to boot my board because the kernel panics for another reason.
