    Subject[PATCH v2 00/11] add thermal throttling to Allwinner A33 SoC
    Date
    The Allwinner SoCs all have an ADC that can also act as a touchscreen
    controller and a thermal sensor. The first four channels can be used
    either for the ADC or the touchscreen and the fifth channel is used for
    the thermal sensor. We currently have a driver for the two latter
    functions in drivers/input/touchscreen/sun4i-ts.c but we don't have
    access to the ADC feature at all. It is meant to replace the current
    driver by using MFD and subdrivers for existing bindings.

    The Allwinner A33 only has a thermal sensor present in the GPADC. In
    addition, there is not an existing DT binding for the GPADC. Thus, we do
    not need the sun4i-gpadc MFD driver which was made to keep DT compatibility
    and probe subdrivers without the need to add DT subnodes.

    This series of patch adds the thermal sensor for the A33 and GPU/CPU
    thermal throttling. It also adds the cpu-supply property to the CPU node
    needed by the Sinlinx SinA33 and Olinuxino A33 to adapt their CPU regulator
    voltage depending on the currently used OPP. The other A33 boards all have
    their cpu-supply property set.

    This series also fixes the missing operating-points-v2 property in cpu DT
    nodes. Finally, it also adds all remaining OPPs which can be found in
    Allwinner 3.4 linux and fex files of all A33 boards.

    This patch *HAS NOT* been tested on the Olinuxino A33.
    @Stefan (or anyone owning an Olinuxino A33), could you test this patch
    series on your board, test CPUfreq and tell us if it works in a stable
    manner? Thanks!

    This series of patch is based on this[1] series of patch.

    SoCs ADC"

    Thanks,
