My situation is the following: * ST75256 driven tft display * via 4-line SPI * software driver under Linux/ARM
I already fixed a hardware adapter. My problem is the software driver under Linux. Currently I thought of writing an extension for the fbtft.
1.) Is there any existing driver solution under linux for this? 2.) How is the best approach for bringing up a ST75256 driven display? 3.) What is the now featured DRM approach to bring this 4-line SPI display driver up, since fbtft is considered to be deprecated?
