Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver specific changes from Olof Johansson: "A collection of mostly SoC-specific driver updates: - a handful of pincontrol and setup changes - new drivers for hwmon and reset controller for vexpress - timing support updates for OMAP (gpmc and other interfaces) - plus a collection of smaller cleanups" * tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits) ARM: ux500: fix pin warning ARM: OMAP2+: tusb6010: generic timing calculation ARM: OMAP2+: smc91x: generic timing calculation ARM: OMAP2+: onenand: generic timing calculation ARM: OMAP2+: gpmc: generic timing calculation ARM: OMAP2+: gpmc: handle additional timings ARM: OMAP2+: nand: remove redundant rounding gpio: samsung: use pr_* instead of printk ARM: ux500: fixup magnetometer pins ARM: ux500: add STM pin configuration ARM: ux500: 8500: add pinctrl support for uart1 and uart2 ARM: ux500: cosmetic fixups for uart0 gpio: samsung: Fix input mode setting function for GPIO int ARM: SAMSUNG: Insert bitmap_gpio_int member in samsung_gpio_chip ARM: ux500: 8500: define SDI sleep states ARM: vexpress: Reset driver ARM: ux500: 8500: update SKE keypad pinctrl table hwmon: Versatile Express hwmon driver ARM: ux500: delete duplicate macro ARM: ux500: 8500: add IDLE pin configuration for SPI ...
