2022-08-17thermal/drivers/mtk: Switch to new of APIDaniel Lezcano1-5/+5
The thermal OF code has a new API allowing to migrate the OF initialization to a simpler approach. The ops are no longer device tree specific and are the generic ones provided by the core code. Convert the ops to the thermal_zone_device_ops format and use the new API to register the thermal zone with these generic ops.

2020-07-31thermal: mediatek: Add tsensor support for V2 thermal systemHenry Yen1-7/+125
This patch adds full support for ver 2 thermal system (e.g., MT7622 SoC). The new changes include reading calibration data, converting temperature and hardware initialization which are specific for version 2 system. Each platform decides which function to call according to its version.

2020-07-31thermal: mediatek: Prepare to add support for other platformsHenry Yen1-52/+62
It is known that Mediatek owns two thermal systems, which only differ in the way of reading calibration data and converting temperature. MT8173, MT8183, MT2701 and MT2712 belongs to version 1 thermal system, and MT7622 belongs to version 2. In order to handle both systems, the suffix _V1 is appended to the current code, and then the second patch will add _V2 functions with the same purpose but different implementation.

2020-07-15Revert "thermal: mediatek: fix register index error"Enric Balletbo i Serra1-4/+2
This reverts commit eb9aecd90d1a39601e91cd08b90d5fee51d321a6 The above patch is supposed to fix a register index error on mt2701. It is not clear if the problem solved is a hang or just an invalid value returned, my guess is the second. The patch introduces, though, a new hang on MT8173 device making them unusable. So, seems reasonable, revert the patch because introduces a worst issue. The reason I send a revert instead of trying to fix the issue for MT8173 is because the information needed to fix the issue is in the datasheet and is not public. So I am not really able to fix it. Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173 devices.

2016-05-17thermal: convert mtk_thermal to use devm_thermal_zone_of_sensor_registerEduardo Valentin1-10/+2
This changes the driver to use the devm_ version of thermal_zone_of_sensor_register and cleans up the local points and unregister calls.

2016-02-18thermal: Add Mediatek thermal controller supportSascha Hauer1-0/+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.
