2018-10-25thermal: rcar_thermal: Prevent doing work after unbindGeert Uytterhoeven1-0/+1
When testing bind/unbind on r8a7791/koelsch: WARNING: CPU: 1 PID: 697 at lib/debugobjects.c:329 debug_print_object+0x8c/0xb4 ODEBUG: free active (active state 0) object type: timer_list hint: delayed_work_timer_fn+0x0/0x10 This happens if the workqueue runs after the device has been unbound. Fix this by cancelling any queued work during remove.

2018-10-25thermal: rcar_thermal: Prevent hardware access during system suspendGeert Uytterhoeven1-2/+2
On r8a7791/koelsch, sometimes the following message is printed during system suspend: rcar_thermal e61f0000.thermal: thermal sensor was broken This happens if the workqueue runs 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").

2018-10-25thermal: add stm32 thermal driverDavid HERNANDEZ SANCHEZ5-2/+777
Add support for DTS thermal sensor that can be found on some STM32 platforms. This driver is based on OF and works in interrupt mode. It offers two temperature trip points: passive and critical. The first is intended for passive cooling notification while the second is used for over-temperature reset.
