Convert the Samsung Exynos4212/4412 SoC Imaging Subsystem (FIMC-IS) bindings to DT schema. Changes during conversion - adjust to existing DTS and Linux driver: add iommus and power-domains. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> Reviewed-by: Rob Herring <robh@xxxxxxxxxx> --- Changes since v2: 1. Move size-cells next to address-cells. 2.
