This series adds initial Linux support for the Parade PS195 DP-to-HDMI
bridge and uses it to enable HDMI on the Qualcomm Glymur CRD family
(Glymur CoB/SiP, Mahua, and Kalambo).

The PS195 operates autonomously using firmware loaded from external
SPI flash — it handles link training, EDID access, and hotplug detection
without host register intervention at runtime, so no existing bridge
driver fits its power-sequencing and reset model.

It introduces:

- a DT binding for PS195 (supplies, optional reset GPIO, and port graph),
- a DRM bridge driver that implements PS195 power sequencing and PM handling, and
- arm64 integration (defconfig + shared glymur-crd.dtsi wiring) so all three
  variants can route DP over USB2 QMP combo PHY to HDMI through PS195.
