Hi, I have to write a device driver for serial (SPI-4) port access to interface the OMAP-L138 based zoom board with a LCD unit (DisplayTech model S64128MX with Sitronix ST7565R controller).
I have some kernel module development experience. But I am a beginner to the DaVinci code base and I am learning on my own. I am confused more about the development environment like the location of the Linux source headers to include, cross compilation etc? Surprisingly I could not find any appropriate document. Can somebody please suggest me the documents or device driver examples (if exists) to refer. I am willing to write from scratch if needed, but there might be already a SPI driver implemented for the OMAP processor, which I have to modify and customize for my requirement.
I would highly appreciate any help in this regard, as it would save me a lot of time. I have already spent a lot of time for nothing, it's simply huge and I don't know where to start.
