* | thermal: exynos: Fix to clear only the generated interruptsAmit Daniel Kachhap2013-08-132-6/+7
| | | | | | | | | | | | | | | | | | | | | | This patch uses the TMU status register to know the generated interrupts and only clear them in the interrupt handler.

* | thermal: exynos: Support thermal trippingAmit Daniel Kachhap2013-08-133-5/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | TMU urgently sends active-high signal (thermal trip) to PMU, and thermal tripping by hardware logic. Thermal tripping means that PMU cuts off the whole power of SoC by controlling external voltage regulator.

* | thermal: exynos: Move register definitions from driver to data fileAmit Daniel Kachhap2013-08-134-117/+315
| | | | | | | | | | | | | | | | | | | | | | | | This patch migrates the TMU register definition/bitfields to data file. This is needed to support SoC's which use the same TMU controller but register validity, offsets or bitfield may slightly vary across SOC's.

* | thermal: exynos: Add extra entries in the tmu platform dataAmit Daniel Kachhap2013-08-134-48/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds entries min_efuse_value, max_efuse_value, default_temp_offset, trigger_type, cal_type, trim_first_point, trim_second_point, max_trigger_level trigger_enable in the TMU platform data structure. Also the driver is modified to use the data passed by these new platform memebers instead of the constant macros. All these changes helps in separating the SOC specific data part from the TMU driver.

* | thermal: exynos: Add missing definations and code cleanupAmit Daniel Kachhap2013-08-131-16/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds some extra register bitfield definations and cleans up the code to prepare for moving register macros and definations inside the TMU data section. In this code cleanup the TMU enable bit is correctly used as bit0 and bit1 is taken care which is reserve bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch renames and moves include/linux/platform_data/exynos_thermal.h to drivers/thermal/samsung/exynos_tmu.h. This file movement is needed as exynos SOC's are not supporting non-DT based platforms and this file now just contains exynos tmu driver related definations.

* Thermal: Fix lockup of cpu_down()Steven Rostedt2013-07-221-1/+0
| | | | | | | | | | | | | | | | | | | | | Commit f1a18a105 "Thermal: CPU Package temperature thermal" had code that did a get_online_cpus(), run a loop and then do a put_online_cpus(). The problem is that the loop had an error exit that would skip the put_online_cpus() part. In the error exit part of the function, it also did a get_online_cpus(), run a loop and then put_online_cpus(). The only way to get to the error exit part is with get_online_cpus() already performed. If this error condition is hit, the system will be prevented from taking CPUs offline. The process taking the CPU offline will lock up hard. Removing the get_online_cpus() removes the lockup as the hotplug CPU refcount is back to zero. This was bisected with ktest.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change updates the ti-soc-thermal driver to use standard GPIO DT bindings to read the GPIO number associated to thermal shutdown IRQ, in case the device features it. Previously, the code was using a specific DT bindings. As now OMAP supports the standard way to model GPIOs, there is no point in having a ti specific binding.

This macro can lead to dangerous results, like returning success (0) during a failure scenario (NULL pointer handling). For this reason this patch is changing the driver after revisiting the code. These are the cases: i. For cases in which IS_ERR_OR_NULL() is used for checking return values of functions that returns either PTR_ERR() or a valid pointer, it has been translated to IS_ERR() check only. ii. For cases that a NULL check is still needed, it has been translated to if (!ptr || IS_ERR(ptr)).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a requirement needing .get_trip_temp() callback function for registering thermal zone device. This function is used when thermal zone is updated and essential where thermal core handles thermal trip based only polling way not hw interrupt.
