And following a quick check, those occurrences all have .fw_name="xo",.name="xo_board", allowing the clock to be provided via DT. For sm6125, I'd like it to be required like that: all dt-bindings require an "xo" board where relevant, after all. - Marijn > > Konrad > > > > >> > >>> > >>> With that fixed: > >> > >> Hence I don't think it makes sense to "fix" this. > >> > >> - Marijn > >> > >>> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> > > > > > >
