[PATCH 2/4] media: dt-bindings: samsung,exynos4212-fimc-lite: convert to dtschema
From: Krzysztof Kozlowski
Date: Sun Feb 12 2023 - 14:03:10 EST
Convert the Samsung Exynos SoC series camera host interface (FIMC-LITE)
bindings to DT schema. Changes during conversion - adjust to existing
DTS and Linux driver: add iommus and power-domains.

-Exynos4x12/Exynos5 SoC series camera host interface (FIMC-LITE)

-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.
