Subject: [PATCH 2/2] pinctrl: add generic pins and functions properties

From: Stephen Warren <swarren@...dia.com>

pinctrl bindings can benefit from generic property names that define
which pins a "pin configuration node" affects, and which mux function
to select onto those pins. Document new properties for this purpose so
that other bindings may refer to them.

 Supported generic properties are:
 
+pins			- the list of pins that properties in the node
+			  apply to
+function		- the mux function to select
 bias-disable		- disable any pin bias
 bias-high-impedance	- high impedance mode ("third-state", "floating")
