Merge tag 'pinctrl' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm-soc pincontrol drivers update from Arnd Bergmann: "We are converting platforms to use the pinctrl framework over time, rather than using platform specific code for the same effect. This adds the respective driver for the prima2 platform." * tag 'pinctrl' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: prima2: enable gpiolib unconditionally PINCTRL: SiRF: add GPIO and GPIO irq support in CSR SiRFprimaII
