[PATCH 1/3] pinctrl: pinctrl-single: enhance to configure multiple pins of different modules

* Manjunathappa, Prakash [off-list ref] [130521 07:13]:

Add support to configure multiple pins in each register, existing
implementation added by [1] does not support full fledge multiple pin
configuration in single register, reports a pin clash when different
modules configure different bits of same register. The issue reported
and discussed here
http://www.spinics.net/lists/arm-kernel/msg235213.html

With pinctrl-single,bits-per-mux property specified, use function-mask
property to find out number pins to configure. Allocate and register
pin control functions based sub mask.

Thanks for fixing this! Looks good to me, and things keep
working for me just fine with these applied:
