    Subject[PATCH v2 07/11] clk: qcom: mmcc-msm8998: Set CLK_GET_RATE_NOCACHE to pixel/byte clks
    Date
    The pixel and byte clocks rate should not be cached, as a VCO shutdown
    may clear the frequency setup and this may not be set again due to the
    cached rate being present.
    This will also be useful when shadow clocks will be implemented in
    the DSI PLL for seamless timing/resolution switch.
