[PATCH v8 04/34] ARM: dts: imx6qdl: add multiplexer controls

From: Steve Longerbeam
Date: Wed Jun 07 2017 - 14:44:56 EST


From: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>

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.
