Subject: [PATCH v5 0/2] Add RK3588 Tiger DisplayPort carrier
Date: Wed, 30 Sep 2026 18:25:42 +0200 [thread overview]
Message-ID: <20260930162545.2357505-1-heiko@sntech.de> (raw)
A board that allows easy testing of the Analogix eDP controller on the
RK3588. Requires Damon's recent work on hotplugging the eDP controller
displays [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.
changes in v5:
- didn't take a year since v4 ;-)
- drop wrong quotes around Rob's Rb
- drop wrong link-trailers that slipped into v4
- disable mmu600_pcie for the time being
- move hpd-gpio back to the dp-connector where it belongs
With v3 of the hpd series, this now works as expected
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
