The FIMC camera node wrapper is not a bus, so using simple-bus fallback compatible just to instantiate its children nodes was never correct. Dropping simple-bus node fixes warnings: exynos4210-smdkv310.dtb: camera: $nodename:0: 'camera' does not match '^([a-z][a-z0-9\\-]+-bus|bus|localbus|soc|axi|ahb|apb)(@.+)?$' The change is not backwards compatible and expects the FIMC driver to populate its children.
