Merge branch 'pinmux-dt' of git://gitorious.org/sirfprima2-kernel/sirfprima2-kernel into next/dt
This branch enables device tree bindings for the CSR Prima pin control
subsystem. All patches acked by Linus W (pinctrl maintainer).
* 'pinmux-dt' of git://gitorious.org/sirfprima2-kernel/sirfprima2-kernel:
pinctrl: sirf: add DT-binding pinmux mapping support
ARM: PRIMA2: rename prima2-cb.dts to prima2.dtsi as it only has SoC features
ARM: PRIMA2: add missing interrupts property for pinctrl node
+ sync to Linux 3.6-rc4
