Signed-off-by: Steve Longerbeam Acked-by: Rob Herring --- Changes since v8 [1]: - expand on description of the MIPI CSI-2 IP core in i.MX6, and drop "snps,dw-mipi-csi2" compatibility for now.

This is a Synopsys Designware MIPI CSI-2 host controller core +combined with a D-PHY core mixed into the same register block. In +addition this device consists of an i.MX-specific "CSI2IPU gasket" +glue logic, also controlled from the same register block. The CSI2IPU +gasket demultiplexes the four virtual channel streams from the host +controller's 32-bit output image bus onto four 16-bit parallel busses +to the i.MX IPU CSIs. + +Required properties: +- compatible : "fsl,imx6-mipi-csi2"; +- reg : physical base address and length of the register set; +- clocks : the MIPI CSI-2 receiver requires three clocks: hsi_tx + (the D-PHY clock), video_27m (D-PHY PLL reference + clock), and eim_podf; +- clock-names : must contain "dphy", "ref", "pix"; +- port@* : five port nodes must exist, containing endpoints + connecting to the source and sink devices according to + of_graph bindings. The first port is an input port, + connecting with a MIPI CSI-2 source, and ports 1 + through 4 are output ports connecting with parallel + bus sink endpoint nodes and correspond to the four + MIPI CSI-2 virtual channel outputs. + +Optional properties: +- interrupts : must contain two level-triggered interrupts, + in order: 100 and 101; -- 2.7.4
