From bc97e88ecd360a730b0f9c96f285b680be496e06 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Mon, 12 Jun 2017 11:23:54 -0700 Subject: [PATCH] ARM: dts: imx6qdl: add multiplexer controls 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.
