The eDP and DP interfaces shared the bridge operations and the eDP specific changes were implemented under is_edp check. To add psr support for eDP, we started using a new set of eDP bridge ops. We are moving the eDP specific code in the dp_bridge_mode_valid function to a new eDP function, edp_bridge_mode_valid under the eDP bridge ops. Signed-off-by:

Add support for basic panel self refresh (PSR) feature for eDP. Add a new interface to set PSR state in the sink from DPU. Program the eDP controller to issue PSR enter and exit SDP to the sink. Signed-off-by:

Use atomic variants for DP bridge callback functions so that the atomic state can be accessed in the interface drivers. The atomic state will help the driver find out if the display is in self refresh state. Signed-off-by:

Reset the datapath after disabling the timing gen, such that it can start on a clean slate when the intf is enabled back. This was a recommended sequence from the DPU HW programming guide. Signed-off-by:

There can be a race between timing gen disable and vblank irq. The wait post timing gen disable may return early but intf disable sequence might not be completed. Ensure that, intf status is disabled before we retire the function. Signed-off-by:

Recommended way of reading the interface timing gen status is via status register. Timing gen status register will give a reliable status of the interface especially during ON/OFF transitions. This support was added from DPU version 5.0.0. Signed-off-by:

The function dpu_plane_sspp_atomic_update() updates pdpu->is_rt_pipe flag, but after the commit 854f6f1c ("drm/msm/dpu: update the qos remap only if the client type changes") it sets the flag late, after all the qos functions have updated QoS programming. Move the flag update back to the place where it happened before the mentioned commit to let the pipe be programmed according to its current RT/non-RT state.

It was left unnoticed during the review that even if there is no OPP table in device tree, one will be created by a call to the function devm_pm_opp_set_clkname(). This leads to dsi_mgr_bridge_mode_valid() rejecting all modes if DT contains no OPP table for the DSI host. Rework dsi_mgr_bridge_mode_valid() to handle this case by actually checking that the table is populated with frequency entries before returning an error.

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:
