[PATCH 01/11] ARM: dts: imx6qdl: add multiplexer controls

[Steve Longerbeam]

From: Philipp Zabel <p.zabel at pengutronix.de>

The IOMUXC General Purpose Register space contains various bitfields
that control video bus multiplexers. Describe them using a mmio-mux
node. The placement of the IPU CSI video mux controls differs between
i.MX6D/Q and i.MX6S/DL.
