| description: | |
| The ADV7533 and ADV7535 are HDMI audio and video transmitters |
| compatible with HDMI 1.4 and DVI 1.0. They support color space |
| conversion, S/PDIF, CEC and HDCP. The transmitter input is MIPI DSI. |

| I2C slave addresses. |
| |
| The ADV7533/35 internal registers are split into four pages |
| exposed through different I2C addresses, creating four register |
| maps. Each map has it own I2C address and acts as a standard slave |
| device on the I2C bus. The main address is mandatory, others are |
| optional and revert to defaults if not specified. |
