sel and top don't make sense. You should not be referencing upper level
clocks.
CLK_VDEC_SOC_LARB1 doesn't make a lot of sense either, since that should
be referenced in the larb. Unless if the clock doesn't get turned on when
the IOMMU is bypassed.
Last, would it work if lat only referenced CLK_VDEC_SOC_LAT, and core only
referenced CLK_VDEC_SOC_VDEC?
Thanks
