[PATCH v3 0/5] Support bridge/connector by Tegra HDMI

From: Svyatoslav Ryhel
Date: Mon Aug 07 2023 - 10:35:41 EST


This patch adds support for the bridge/connector attached to the
HDMI output, allowing to model the hardware properly. It keeps
backwards compatibility with existing bindings and is required
by devices which have a simple or MHL bridge connected to HDMI
output like ASUS P1801-T or LG P880/P895 or HTC One X.

Tested on ASUS Transformers which have no dedicated bridge but
have type d HDMI connector directly available. Tests went smoothly.

Changes from v2:
- added missing descriptions to tegra dc and hdmi yamls
- fixed "Warning (unit_address_vs_reg): /host1x@50000000/
dc@54200000/rgb/port@0: node has a unit name, but no reg or
ranges property"
- dropped reg from port to avoid same warning with hdmi ports

Changes from v1:
- no changes, re-sending
