Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Olof Johansson: "Driver updates for ARM SoCs. A slew of changes this release cycle. The reset driver tree, that we merge through arm-soc for historical reasons, is also sizable this time around. Among the changes: - clps711x: Treewide changes to compatible strings, merged here for simplicity. - Qualcomm: SCM firmware driver cleanups, move to platform driver - ux500: Major cleanups, removal of old mach-specific infrastructure. - Atmel external bus memory driver - Move of brcmstb platform to the rest of bcm - PMC driver updates for tegra, various fixes and improvements - Samsung platform driver updates to support 64-bit Exynos platforms - Reset controller cleanups moving to devm_reset_controller_register() APIs - Reset controller driver for Amlogic Meson - Reset controller driver for Hisilicon hi6220 - ARM SCPI power domain support" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (100 commits) ARM: ux500: consolidate base platform files ARM: ux500: move soc_id driver to drivers/soc ARM: ux500: call ux500_setup_id later ARM: ux500: consolidate soc_device code in id.c ARM: ux500: remove cpu_is_u* helpers ARM: ux500: use CLK_OF_DECLARE() ARM: ux500: move l2x0 init to .init_irq mfd: db8500 stop passing around platform data ASoC: ab8500-codec: remove platform data based probe ARM: ux500: move ab8500_regulator_plat_data into driver ARM: ux500: remove unused regulator data soc: raspberrypi-power: add CONFIG_OF dependency firmware: scpi: add CONFIG_OF dependency video: clps711x-fb: Changing the compatibility string to match with the smallest supported chip input: clps711x-keypad: Changing the compatibility string to match with the smallest supported chip pwm: clps711x: Changing the compatibility string to match with the smallest supported chip serial: clps711x: Changing the compatibility string to match with the smallest supported chip irqchip: clps711x: Changing the compatibility string to match with the smallest supported chip clocksource: clps711x: Changing the compatibility string to match with the smallest supported chip clk: clps711x: Changing the compatibility string to match with the smallest supported chip ...
