It doesn't constitute a full device tree 15 binding specification by itself but is meant to be referenced by device tree 16 bindings for the platform-specific integrations of the DWC HDMI TX. 17 18 When referenced from platform device tree bindings the properties defined in 19 this document are defined as follows. The platform device tree bindings are 20 responsible for defining whether each property is required or optional. 21 22 properties: 23 reg: 24 maxItems: 1 25 26 reg-io-width: 27 description: 28 Width (in bytes) of the registers specified by the reg property. 29 enum: [1, 4] 30 default: 1 31 32 clocks: 33 minItems: 2 34 maxItems: 5 35 items: 36 - description: The bus clock for either AHB and APB 37 - description: The internal register configuration clock 38 additionalItems: true 39 40 clock-names: 41 minItems: 2 42 maxItems: 5 43 items: 44 - const: iahb 45 - const: isfr 46 additionalItems: true 47 48 ddc-i2c-bus: 49 $ref: /schemas/types.yaml#/definitions/phandle 50 deprecated: true 51 description: 52 The HDMI DDC bus can be connected to either a system I2C master or the 53 functionally-reduced I2C master contained in the DWC HDMI.
