    Subject[PATCH v4 08/15] arm64: dts: qcom: sdm845: Add missing clocks / fix names on the gpucc
    Date
    We're transitioning over to requiring the Qualcomm GPU Clock
    Controller to specify all the input clocks. Let's add them for
    sdm845.

    As part of this we've decided that the xo clock should be referred to
    in the bindings as "bi_tcxo". Change the dts.

    NOTE: Until the Linux driver for sdm845's gpucc is updated, these
    clocks will not actually be used in Linux. It will continue to use
    global clock names to match things up. Of course, Linux didn't use
    the old "xo" clock anyway.

    Changes in v4: None
    Changes in v3:
    - Unlike in v2, use internal name instead of purist name.

    Changes in v2:
    - Patch ("arm64: dts: qcom: sdm845: Add...gpucc") new for v2.
