Introduce GPIO-based driver for MIPI DBI class that allows MIPI DBI type A and B displays to be used on general platforms. Since each data pin GPIO can be selected individually, the bus pins are set in a loop, which has a significant negative impact on performance. When using 8-bit mode and all the data GPIO pins are on the same port, a look-up table is generated to set the whole port at once as a performance optimization. This creates a ROM overhead of about 1 kiB. Tested 8-bit 8080 mode with ILI9486 display on nRF52840-DK board. Signed-off-by: Stefan Gloor <code@stefan-gloor.ch> |
