2019-05-14drivers: thermal: tsens: Introduce IP-specific max_sensor countAmit Kucheria4-2/+6
The IP can support 'm' sensors while the platform can enable 'n' sensors of the 'm' where n <= m. Track maximum sensors supported by the IP so that we can correctly track what subset of the sensors are supported on the platform.

2019-05-14drivers: thermal: tsens: Don't print error message on -EPROBE_DEFERAmit Kucheria1-1/+2

2019-05-14drivers: thermal: tsens: Introduce reg_fields to deal with register descriptionAmit Kucheria5-58/+370
As we add support for newer versions of the TSENS IP, the current approach isn't scaling because registers and bitfields get moved around, requiring platform-specific hacks in the code. By moving to regmap, we can hide the register level differences away from the code. Define a common set of registers and bit-fields that we care about across the various tsens IP versions.

2019-05-06thermal/drivers/core: Remove the module Kconfig's optionDaniel Lezcano1-2/+2
The module support for the thermal subsystem makes little sense: - some subsystems relying on it are not modules, thus forcing the framework to be compiled in - it is compiled in for almost every configs, the remaining ones are a few platforms where I don't see why we can not switch the thermal to 'y'. The drivers can stay in tristate. - platforms need the thermal to be ready as soon as possible at boot time in order to mitigate Usually the subsystems framework are compiled-in and the plugs are as module. Remove the module option. The removal of the module related dead code will come after this patch gets in or is acked.

The driver makes use of the implementation details of the thermal framework to retrieve a pointer to its private data from a struct thermal_zone_device, and gets it wrong - leading to the crash.
