Sure, let's keep in touch about this!

I also have the 7" LVDS LCD that goes with it, which was supported by
Parthiban's initial series (but needs rework, and it seems that he's
unlikely to do it). I also have the 5" MIPI LCD but it's less likely
that it will be supported, although I have seen dirty patches to make
some other MIPI panel work with A133.

We'll need PWM for it which should be a follow-up to the current H616
PWM series from Richard Genoud.

Other than that there is a PCF8563TS RTC on the board, audio stuff:
speaker (which I have) mic and headphones and a GPIO beeper which could
be added.

Do you have other A133 boards that you're interested in?
I also have:
- KICKPI K5C
- DshanPi-R818
- Logicom La Tab 129
- Trimui Brick

And have some WIP device-trees and u-boot for most of them.

All the best,

Paul
