[Letux-kernel] [PATCH v11 5/8] MIPS: DTS: jz4780: Account for Synopsys HDMI driver and LCD controllers

From: Paul Boddie <paul at boddie.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.

Here we add jz4780 device tree setup.
