Subject: [RFC v3 6/8] MIPS: DTS: jz4780: account for Synopsys HDMI driver and LCD controller

From: Paul Boddie <paul@...die.org.uk>

A specialisation of the generic Synopsys HDMI driver is employed for JZ4780
HDMI support. This requires a new driver, plus device tree and configuration
modifications.
