Currently we do not differentiate between the various users of the qcom,mdss-dsi-ctrl. The driver is flexible enough to operate from one compatible string but, the hardware does have some significant differences in the number of clocks. To facilitate documenting the clocks add the following compatible strings - qcom,apq8064-dsi-ctrl - qcom,msm8916-dsi-ctrl - qcom,msm8953-dsi-ctrl - qcom,msm8974-dsi-ctrl - qcom,msm8996-dsi-ctrl - qcom,msm8998-dsi-ctrl - qcom,sc7180-dsi-ctrl - qcom,sc7280-dsi-ctrl - qcom,sdm660-dsi-ctrl - qcom,sdm845-dsi-ctrl - qcom,sm8150-dsi-ctrl - qcom,sm8250-dsi-ctrl - qcom,sm8350-dsi-ctrl - qcom,sm8450-dsi-ctrl - qcom,sm8550-dsi-ctrl - qcom,qcm2290-dsi-ctrl Deprecate qcom,dsi-ctrl-6g-qcm2290 in favour of the desired format while we do so. Several MDSS yaml files exist which document the dsi sub-node. For each existing SoC MDSS yaml, provide the right dsi compat string. Acked-by:

When converting from .txt to .yaml we didn't include descriptions for the existing regulator supplies. - vdd - vdda - vddio Add those descriptions into the yaml now as they were prior to the conversion. In the .txt description we marked these regulators as required, however, that requirement appears to have been in error. Taking the example of sc7180-trogdor-wormdingler.dtsi. The avdd and avee come from GPIO controlled external regulators, not the SoC and in this case there's no need for vddio to power an I/O bus. Similarly the regulators for the LCD are controlled by the panel driver not by the dsi-ctrl driver. It would be possible to connect a different type of panel to the DSI bus here in which case we may or may not want to make use of vdd, vdda or vddio. This is also the case for older chipsets like apq8064, msm8916 etc the vdd* regulators in the dsi-ctrl block are helpers not dependencies. Add the description of vdd, vdda and vddio back in for the existing upstream dts where vdd, vdda or vddio are already declared but, don't declare those regulators required - they are not SoC requirements.

power-domain is required for the sc7180 dispcc GDSC but not every qcom SoC has a similar dependency for example the apq8064. 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_oneplus_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.
