But it would be really nice if this was labeled mdss_edp_out instead (or possibly defined within the &mdss_edp node).

Hi Bjorn, 1. I will change the edp_out label to mdss_edp_out. 2. The "pm8350c_pwm" node is part of the dependent series mentioned in the cover letter. Below is the patch for the same: https://patchwork.kernel.org/project/linux-arm-msm/patch/1637917920-22041-4-git-send-email-quic_c_skakit@quicinc.com/ 3. I will move the edp_backlight and edp_panel nodes to the root.
