| Yeah it means Kconfig, Makefile and dependencies between config options.

OK.  I know you were interested in these relationships and it's one
reason why I sent this as RFC here first.  So it will wait for you.

|
| I ment e.g.:
| +#define GTA02v1_GPIO_WLAN_GPIO10       S3C2440_GPJ2

Well, OK :-)  It wasn't commented as v1 only.  I'll scrub it a bit more.

|> [data flow on USB explanation]
|
| Hmmm so did i get it correct:
| The first function is called when USB is connected physically, which
| means we can draw 100mA or 1000mA depending on the "charger". Then
| when the host actually enumerates the USB device the second function
| is called and we are allowed to pull 500mA. When removing USB the
| first function is called again and stops charging. Is this correct?

Yep.  Running the workqueue gets it to "reassess" charging limit on a
hint that something changed.
