BeagleY-AI uses this it66122 as the old part is no longer in production as far as I understand. Now, BeaglePlay uses it66121 at the moment, but at some point, it might end up flipping over to the new part. Additionally, it also looks like Revision D of BeagleBone Black switched over to it66122 as well. Changes in V4: * Added patch to sort the compatibles alpha-numerically * vid/pid lookup is done without using the match_data. * picked reviews Changes in V3: Based on Tomi's and Devarsh's reviews, and searching online (and failing to find) for a public data sheet, I have refactored the series to: a) Detect the ID by matching vid/pid b) Introduce it66122 basic support which seems to work based on empirical testing evidence on BeagleY-AI. This allows incremental patches in the future by someone who might have access to the data sheet to add additional features for the chip. c) Irritated by checkpatch --strict warnings, added a patch to fix existing warnings as part of this series, but it could probably go in independent of everything else. d) Stopped claiming it66122 is drop in replacement of it66121 :) Changes in V2: * Picked up Krystoff's binding ack * Switched over to a vid/pid list V3: https://lore.kernel.org/all/20250815034105.1276548-1-nm@ti.com/ V2: https://lore.kernel.org/all/20250813204106.580141-1-nm@ti.com/ V1: https://lore.kernel.org/all/20250813190835.344563-1-nm@ti.com/ Nishanth Menon (5): dt-bindings: display: bridge: it66121: Add compatible string for IT66122 drm/bridge: it66121: Drop ftrace like dev_dbg() prints drm/bridge: it66121: Sort the compatibles drm/bridge: it66121: Use vid/pid to detect the type of chip drm/bridge: it66121: Add minimal it66122 support .../bindings/display/bridge/ite,it66121.yaml | 1 + drivers/gpu/drm/bridge/ite-it66121.c | 66 +++++++++---------- 2 files changed, 33 insertions(+), 34 deletions(-) -- 2.47.0
