*	pinctrl: implement pinctrl deferred probing	Linus Walleij	2012-04-18	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	If drivers try to obtain pinctrl handles for a pin controller that has not yet registered to the subsystem, we need to be able to back out and retry with deferred probing. So let's return -EPROBE_DEFER whenever this location fails. Also downgrade the errors to info, maybe we will even set them to debug once the deferred probing is commonplace.

*	pinctrl: core device tree mapping table parsing support	Stephen Warren	2012-04-18	1	-0/+249
	During pinctrl_get(), if the client device has a device tree node, look for the common pinctrl properties there. If found, parse the referenced device tree nodes, with the help of the pinctrl drivers, and generate mapping table entries from them. During pinctrl_put(), free any results of device tree parsing.
