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.

3-D look-up tables (CLU), 1D-histogram generation (HGO), and color
|
|
space conversion (CSC).
