[PATCH v4 9/9] pinctrl: single: dump pinmux register value

[Tony Lindgren]

* Haojian Zhuang <haojian.zhuang at gmail.com> [121107 07:22]:
> Dump pinmux register value, not only function part in the pinmux
> register.
> 
> Also fix the issue on caluclating pin offset. The last parameter
> should be pin number, not register offset.
