Subject: [PATCH v3 5/5] arm64: dts: renesas: eagle: Enable HDMI output
Date: Thu, 12 Apr 2018 10:14:01 +0200	[thread overview]
Message-ID: <1523520841-16455-6-git-send-email-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <1523520841-16455-1-git-send-email-jacopo+renesas@jmondi.org>

Enable HDMI output on Renesas R-Car V3M Eagle board.

The HDMI ouput is enabled connecting the DU LVDS output to the
transparent LVDS converter THC63LVD1024, and successively routing its
RGB output to the ADV7511W HDMI encoder.

v1 -> v2:
- Squash patches [5/7], [6/7] and [7/7] of v1 in a single patch as
  suggested by Laurent
- Remove DU pinmuxing as it is used for DU parallel RGB output only used
  by Eagle's display expander board not enabled by this series.
