They support color space 15 conversion, S/PDIF, CEC and HDCP. The transmitter input is MIPI DSI. 16 17properties: 18 compatible: 19 enum: 20 - adi,adv7533 21 - adi,adv7535 22 23 reg: 24 description: | 25 I2C slave addresses. 26 27 The ADV7533/35 internal registers are split into four pages 28 exposed through different I2C addresses, creating four register 29 maps.
