Subject: [PATCH v4 0/2] Add RK3588 Tiger DisplayPort carrier
Date: Fri, 10 Oct 2025 00:50:48 +0200 [thread overview]
Message-ID: <20251009225050.88192-1-heiko@sntech.de> (raw)
A board that allows easy testing of the Analogix eDP controller on the
RK3588. Requires Damon's recent work on allowing bridges in the
Rockchip variant of the controller driver [0].
Concerning displays, my current setup is
DP-carrier -> DP-port -> DP-to-eDP converter from Aliexpress -> eDP panel
which produces a nice 1080p image, but it seems Quentin's experience was
not as nice, as he reported in v2 [1] that his two test monitors produced
dfferent tints, but not real output with:
green tint on a Iiyama ProLite XU2294HSU and purple tint on a Dell P2319H
changes in v4:
- move hpd-gpio down the the analogix-dp node
As stated in commit cb640b2ca546 ("drm/bridge: display-connector: don't
set OP_DETECT for DisplayPorts") the dp-connector can't just read the
hpd-gpio and mark that as monitor detected, instead
changes in v3:
- rebase on top of 6.17-rc1
- still should wait on the analogix bridge support
changes in v2:
- collect Ack/Review for binding
- address Quentin's comments
- sorting in Makefile and dp-connector properties
- ethernet alias
- drop data-lanes comment
