Most Qcom SoC's using mdss-dsi-ctrl seem to have the ability to power-collapse the MDP without collapsing DSI. For example the qcom vendor kernel commit for apq8084, msm8226, msm8916, msm8974. https://review.carbonrom.org/plugins/gitiles/CarbonROM/android_kernel_onepl= us_msm8994/+/7b5c011a770daa2811778937ed646237a28a8694 "ARM: dts: msm: add mdss gdsc supply to dsi controller device It is possible for the DSI controller to be active when MDP is power collapsed. DSI controller needs to have it's own vote for mdss gdsc to ensure that gdsc remains on in such cases." This however doesn't appear to be the case for the apq8064 so we shouldn't be marking power-domain as required in yaml checks.
