description: |+
Renesas R-Car color management module connected to R-Car DU video channels.
It provides image enhancement functions such as 1-D look-up tables (LUT),
3-D look-up tables (CLU), 1D-histogram generation (HGO), and color
space conversion (CSC).

dt-bindings: Clean-up schema indentation formatting Fix various inconsistencies in schema indentation. Most of these are list indentation which should be 2 spaces more than the start of the enclosing keyword. This doesn't matter functionally, but affects running scripts which do transforms on the schema files.

dt-bindings: Fix incorrect 'reg' property sizes The examples template is a 'simple-bus' with a size of 1 cell for had between 2 and 4 cells which really only errors on I2C or SPI type devices with a single cell. The easiest fix in most cases is to change the 'reg' property to for 1 cell address and size. In some cases with child devices having 2 cells, that doesn't make sense so a bus node is needed.
