| | | | | | | | | | This patch adds support for mt2712 chip to mtk_thermal, and integrate mt2712 into the same mediatek thermal driver. MT2712 has only 1 bank and 4 sensors.

* thermal: mt8173: minor mtk_thermal.c cleanupsDawei Chien2017-04-231-1/+1
| | | | | | | | | | | | | | | | If thermal bank with 4 sensors, thermal driver should read TEMP_MSR3. However, currently thermal driver would not read TEMP_MSR3 since mt8173 thermal driver only use 3 sensors on each thermal bank at the same time, so this patch would not effect temperature. Only if mt mt8173 thermal driver use 4 sensors on any thermal bank, would read third sensor two times, and lose fourth sensor of vale. cc: stable@vger.kernel.org Fixes: b7cf0053738c ("thermal: Add Mediatek thermal driver for mt2701.")

* thermal: Add Mediatek thermal controller supportSascha Hauer2016-02-181-0/+623
This adds support for the Mediatek thermal controller found on MT8173 and likely other SoCs. The controller is a bit special. It does not have its own ADC, instead it controls the on-SoC AUXADC via AHB bus accesses. For this reason we need the physical address of the AUXADC. Also it controls a mux using AHB bus accesses, so we need the APMIXEDSYS physical address aswell.
