2018-10-22thermal: tsens: Rename map field in order to add a second address mapAmit Kucheria4-28/+27
The TSENS driver currently only uses a limited set of registers from the TM address space. So it was ok to map just that set of registers and call it "map". We'd now like to map a second set: SROT registers to introduce new functionality. Rename the "map" field to a more appropriate "tm_map". The 8960 doesn't have a clear split between TM and SROT registers. To avoid complicating the data structure, it will switchover to using tm_map for its maps.

2016-09-27thermal: qcom: tsens-8916: mark PM functions __maybe_unusedArnd Bergmann1-2/+2
The newly added tsens-8916 driver produces warnings when CONFIG_PM is disabled: drivers/thermal/qcom/tsens.c:53:12: error: 'tsens_resume' defined but not used [-Werror=unused-function] static int tsens_resume(struct device *dev) ^~~~~~~~~~~~ drivers/thermal/qcom/tsens.c:43:12: error: 'tsens_suspend' defined but not used [-Werror=unused-function] static int tsens_suspend(struct device *dev) ^~~~~~~~~~~~~ This marks both functions __maybe_unused to let the compiler know that they might be used in other configurations, without adding ugly #ifdef logic.

2016-09-27thermal: streamline get_trend callbacksSascha Hauer2-4/+6
The .get_trend callback in struct thermal_zone_device_ops has the prototype: int (*get_trend) (struct thermal_zone_device *, int, enum thermal_trend *); whereas the .get_trend callback in struct thermal_zone_of_device_ops has: int (*get_trend)(void *, long *); Streamline both prototypes and add the trip argument to the OF callback aswell and use enum thermal_trend * instead of an integer pointer. While the OF prototype may be the better one, this should be decided at framework level and not on OF level.
