Work in Progress: LCD driver for AM335x evaluation module

May 5, 2013 — Leave a comment

I’m trying to wrap up some project I started working on quite some time ago and this is first chunk of clean-up.

Patch contains:

  • Kernel config for AM335x EVM
  • dts file for AM335x EVM with TFT panel info
  • LCD controller driver with some functionality missing: only 24/32 bit depth and only TFT mode is supported
  • Really simple PWM driver. LCD backlight is controlled through eCAS submodule of PWMSS0 module.

I tested it only on evaluation module, although I think with proper panel/pinmux configuration it should work with BeagleBone’s LCD caps too.
Parts missing: adjusting clock to proper pixel frequency, proper allocation of framebuffer memory.
