[PATCH] dt-bindings: misc: add documentation for MediaLB DIM2 controller

[Kartik Nair]

Add device tree binding documentation for the MediaLB DIM2 hardware
dependent module. This documents the compatible strings used in
drivers/staging/most/dim2/dim2.c which were previously flagged as
undocumented by checkpatch.

Documented compatible strings:
- fsl,imx6q-mlb150 (Freescale i.MX6Q)
- renesas,mlp (Renesas Gen2)
- renesas,rcar-gen3-mlp (Renesas Gen3)
- xlnx,axi4-os62420_3pin-1.00.a (Xilinx 3-pin)
- xlnx,axi4-os62420_6pin-1.00.a (Xilinx 6-pin)
