thermal: enable broadcom menu for arm64 bcm2835

2018-11-21T08:24:07+00:00

commit fec3624f0bcdb6b20ef9ccf9d9d55d0d75d776f8 upstream. Moving the bcm2835 thermal driver to the broadcom directory prevented it from getting enabled for arm64 builds, since the broadcom directory is only available when 32-bit specific ARCH_BCM is set. Fix this by enabling the Broadcom menu for ARCH_BCM or ARCH_BCM2835.

thermal: da9062/61: Prevent hardware access during system suspend

[ Upstream commit 760eea43f8c6d48684f1f34b8a02fddc1456e849 ] The workqueue used for monitoring the hardware may run while the device is already suspended. Fix this by using the freezable system workqueue instead, cfr. commit 51e20d0e3a60cf46 ("thermal: Prevent polling from happening during system suspend").

thermal: of-thermal: disable passive polling when thermal zone is disabled

2018-10-04T00:00:57+00:00

[ Upstream commit 152395fd03d4ce1e535a75cdbf58105e50587611 ] When thermal zone is in passive mode, disabling its mode from sysfs is NOT taking effect at all, it is still polling the temperature of the disabled thermal zone and handling all thermal trips, it makes user confused. The disabling operation should disable the thermal zone behavior completely, for both active and passive mode, this patch clears the passive_delay when thermal zone is disabled and restores it when it is enabled.

thermal: bcm2835: Stop using printk format %pCr

2018-07-03T09:24:48+00:00

commit bd2a07f71a1e2e198f8a30cb551d9defe422d83d upstream. Printk format "%pCr" will be removed soon, as clk_get_rate() must not be called in atomic context. Replace it by printing the variable that already holds the clock rate. Note that calling clk_get_rate() is safe here, as the code runs in task context.

thermal: exynos: Propagate error value from tmu_read()

2018-05-16T08:10:30+00:00

commit c8da6cdef57b459ac0fd5d9d348f8460a575ae90 upstream. tmu_read() in case of Exynos4210 might return error for out of bound values. Current code ignores such value, what leads to reporting critical temperature value. Add proper error code propagation to exynos_get_temp() function.

thermal: exynos: Reading temperature makes sense only when TMU is turned on

2018-05-16T08:10:30+00:00

commit 88fc6f73fddf64eb507b04f7b2bd01d7291db514 upstream. When thermal sensor is not yet enabled, reading temperature might return random value. This might even result in stopping system booting when such temperature is higher than the critical value. Fix this by checking if TMU has been actually enabled before reading the temperature. This change fixes booting of Exynos4210-based board with TMU enabled (for example Samsung Trats board), which was broken since v4.4 kernel release.

thermal: imx: Fix race condition in imx_thermal_probe()

2018-04-24T07:36:34+00:00

commit cf1ba1d73a33944d8c1a75370a35434bf146b8a7 upstream. When device boots with T > T_trip_1 and requests interrupt, the race condition takes place. The interrupt comes before THERMAL_DEVICE_ENABLED is set. This leads to an attempt to reading sensor value from irq and disabling the sensor, based on the data->mode field, which expected to be THERMAL_DEVICE_ENABLED, but still stays as THERMAL_DEVICE_DISABLED. Afher this issue sensor is never re-enabled, as the driver state is wrong. Fix this problem by setting the 'data' members prior to requesting the interrupts.
