Subject: [v1 3/4] arm64: ls1028aqds: Add support DP nodes for LS1028AQDS
Date: Wed, 8 May 2019 10:35:30 +0000	[thread overview]
Message-ID: <20190508103703.40885-3-wen.he_1@nxp.com> (raw)
In-Reply-To: <20190508103703.40885-1-wen.he_1@nxp.com>

This patch add HDP PHY Controller related nodes on the LS1028AQDS.
Now LS1028AQDS on DP has following features:
- Supports 4 dp lane channel and lane mapping is 1-0-3-2.
- By default, the pixel link rate value's 27Mhz.
- By default, support the resoluions are 4k@60,1080p@60,720p@60,
480p@60. also user can specify any combination of monitor supported
resoluions by written in the node 'resoluion'.
- By default, the edid function is not in use.
