Mark these clocks as protected, to allow the board to boot. Signed-off-by: Bjorn Andersson Reviewed-by: Konrad Dybcio Reviewed-by: Luca Weiss Reviewed-by: Dmitry Baryshkov --- 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.
