Hi,

This patch set aims to add NXP i.MX93 parallel display format configuration
DRM bridge driver support. i.MX93 mediamix blk-ctrl contains one
DISPLAY_MUX register which configures parallel display format by using
the "PARALLEL_DISP_FORMAT" field. i.MX93 LCDIF display controller's
parallel output connects with this piece of small logic to configure
parallel display format.

Patch 1/2 adds NXP i.MX93 parallel display format configuration dt-bindings.

Patch 2/2 adds NXP i.MX93 parallel display format configuration DRM bridge
driver support.

v1->v2:
* Set *num_input_fmts to zero in case
  imx93_pdfc_bridge_atomic_get_input_bus_fmts() returns NULL in patch 2/2.
* Replace .remove callback with .remove_new callback in
  imx93_pdfc_bridge_driver in patch 2/2.
