Detailed Description

Public APIs for MIPI-DBI drivers.

MIPI-DBI defines the following 3 interfaces: Type A: Motorola 6800 type parallel bus Type B: Intel 8080 type parallel bus Type C: SPI Type (1 bit bus) with 3 options:

1. 9 write clocks per byte, final bit is command/data selection bit
2. Same as above, but 16 write clocks per byte
3. 8 write clocks per byte. Command/data selected via GPIO pin The current driver interface does not support type C with 16 write clocks (option 2).
