I have successfully enable the RK903 wifi module on top of Galland's 3.0.36+ kernel source
I have basically inspected the Finless 2.1 kernel and copied the register values of PWM2 and enable it in our sdmmc driver of the kernel.
So here are the files:
1. my .config
2. patch file ( please note that there are some unnecessary debugging statements, remove them if you want)
Please try them at your own risk as you know I am messing with the PWM2 which may imply controlling voltages of the wifi module.
I would appreciate if anyone could improve the code :P
