Mark these clocks as protected, to allow the board to boot. In contrast to the present QCM6490 boards GCC_EDP_CLKREF_EN is left out, as this does not need to be "protected" and is used on the RB3Gen2 board. Reviewed-by: Dmitry Baryshkov Reviewed-by: Luca Weiss Reviewed-by: Konrad Dybcio Signed-off-by: Bjorn Andersson --- I did notice Taniya's patch [1] after writing this patch. I'd prefer to merge this minimal set asap, to make the board boot, unless there's a strong argument for including those other clocks in the protected list.
