Work in Progress: LCD driver for AM335x evaluation module

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

Patchcontains:

• 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.
