Subject: [PATCH v4 0/2] drm/bridge: imx: Add i.MX93 parallel display format configuration support

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 subnode
in i.MX93 mediamix blk-ctrl dt-binding.

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

v3->v4:
* Use dev_err_probe() in imx93_pdfc_bridge_probe() in patch 2/2. (Krzysztof)
* Drop MODULE_ALIAS() in patch 2/2. (Krzysztof)
* Update year of Copyright in patch 2/2.

v2->v3:
* Define i.MX93 parallel display format configuration subnode in
  i.MX93 mediamix blk-ctrl dt-binding. (Rob)
* Resend with Conor's R-b tag on patch 1/2 and with the patch set rebased
  upon v6.11-rc1.

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.
