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:

v2.5.0 support was originally added for SC7280, but this hw is also present on SM8350, which has one more DSI host. Bump up the dsi count and fill in the register of the secondary host to allow it to probe. This should not have any adverse effects on SC7280, as the secondary CTRL will only be touched if it's defined, anyway. Fixes: 65c391b3 ("drm/msm/dsi: Add DSI support for SC7280") Signed-off-by:

According to the vendor kernel, byte intf clock rate should be a half of the byte clock only when DSI PHY version is above 2.0 (in other words, 10nm PHYs and later) and only if PHY is used in D-PHY mode. Currently MSM DSI code handles only the second part of the clause (C-PHY vs D-PHY), skipping DSI PHY version check, which causes issues on some of 14nm DSI PHY platforms (e.g. qcm2290). Move divisor selection to DSI PHY code, pass selected divisor through shared timings and set byte intf clock rate accordingly. Cc: Loic Poulain <loic.poulain@linaro.org> Signed-off-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.

Currently there is no protection against a user trying to set an unsupported mode on DSI. Implement a check based on the opp table whether the byte clock for the mode can be supported by validating whether an opp table entry exists. For devices which have not added opp table support yet, skip this check otherwise it will break bootup on those devices. changes in v3: - make the comment shorter - handle all errors except ENODEV Closes: https://gitlab.freedesktop.org/drm/msm/-/issues/15Reported-by:
