Subject: [PATCH 0/2] drm: bridge: Add TI tmds181 and sn65dp159 driver (RFC)
Date: Tue, 12 Aug 2025 16:51:33 +0200	[thread overview]
Message-ID: <20250812145256.135645-1-mike.looijmans@topic.nl> (raw)
In-Reply-To: <1b153bce-a66a-45ee-a5c6-963ea6fb1c82.949ef384-8293-46b8-903f-40a477c056ae.c8608b8f-6aa9-4650-b701-3b3ffa0b2b1d@emailsignatures365.codetwo.com>


In the past I've seen (and contributed to) hacks that model the chips as
phy or even (really!) clock drivers. Since the chip usually sits between
a signal that is (almost) HDMI and a HDMI connector, I decided to stop
lying and write it as a DRM bridge driver.

I'm fully aware that both bindings and driver require some more rework,
the bindings aren't complete yet and the driver needs some more #defines
for bitfields and such (the core code is over 5 years old).

My main question to the maintainers here: Is this a viable solution?
And if so, I'll do my best to document and clean it up further...
