Hi Kory,
Thanks for the series.

The starting point for this work was adding support for the HDMI cape:
https://www.seeedstudio.com/Seeed-Studio-BeagleBone-Green-HDMI-Cape.html
This will be sent in a later series.

Initially, Miguel proposed modifying the ite-it66121 bridge to support
the legacy behavior without the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag:
https://lore.kernel.org/lkml/20250909-it66121-fix-v1-1-bc79ca83df17@bootlin.com/ (local)
This patch was NAK'd as we don't want to add more legacy code. Maxime
requested that the tilcdc driver be updated to use
DRM_BRIDGE_ATTACH_NO_CONNECTOR instead.

While working on this update, I discovered that the tilcdc driver
contained significant amounts of legacy code that needed cleaning.
Since this driver was developed alongside the tda998x driver for
several AM335x boards, the tda998x driver also required cleanup and
support for the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag.

This series is based on the tilcdc fix sent to mainline:
https://lore.kernel.org/lkml/20251125090546.137193-1-kory.maincent@bootlin.com/ (local)

Patch 1-7: Convert tilcdc binding to YAML and remove the ti,tilcdc,panel
	   sub-binding and driver
Patch 8-16: Clean up tilcdc driver
Patch 17-19: Clean up tda998x driver
Patch 20: Add DRM_BRIDGE_ATTACH_NO_CONNECTOR support to tda998x
Patch 21: Add DRM_BRIDGE_ATTACH_NO_CONNECTOR support to tilcdc

I was trying to test the patches, unable to find the base-commit, are
you using drm-misc-next?

Regards,
Swamil.
