[ Vendor DTS for easy reference: ]
[ https://git.codelinaro.org/clo/la/kernel/msm-4.4/-/blob/caf_migration/kernel.lnx.4.4.r38-rel/arch/arm/boot/dts/qcom/msm8998.dtsi ]

In the queue, we have a patch enabling the Venus Decoder (VDEC) in mainline.
(It is using the previously proposed "qcom,no-low-power" mechanism, but that
might not be necessary, if I understand correctly?)

@Vikash, are you saying that perhaps the DTS for video-codec@cc00000
needs to be written slightly differently?
