V2: - Consistently use fsl,imx8mp-ldb as compatible - Drop items: from compatible: - Replace minItems with maxItems in clocks: - Drop quotes from clock-names const: ldb - Rename syscon to fsl,syscon - Use generic name of ldb-lvds in example V3: - Add AB from Sam - Consistently use MX8MP V4: - Rename to fsl-ldb all over the place - Put the LDB node under media block controller in the example
