-Required properties:
-
-- compatible : should be one of:
- "samsung,exynos4212-fimc-lite" for Exynos4212/4412 SoCs,
- "samsung,exynos5250-fimc-lite" for Exynos5250 compatible
- devices;
-- reg : physical base address and size of the device memory mapped
- registers;
-- interrupts : should contain FIMC-LITE interrupt;
-- clocks : FIMC LITE gate clock should be specified in this property.
-- clock-names : should contain "flite" entry.
-
-Each FIMC device should have an alias in the aliases node, in the form of
-fimc-lite<n>, where <n> is an integer specifying the IP block instance.
