  • 89945047b   thermal: mediatek: Add tsensor support for V2 thermal system ... Browse Code »

    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.

    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.

    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.

    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.

    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.
