Merge tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm-soc: soc specific changes (part 2) from Olof Johansson: "This adds support for the spear13xx platform, which has first been under review a long time ago and finally been completed after generic spear work has gone into the clock, dt and pinctrl branches. Also a number of updates for the samsung socs are part of this branch." Fix up trivial conflicts in drivers/gpio/gpio-samsung.c that look much worse than they are: the exonys5 init code was refactored in commit fd454997d687 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and then commit f10590c9836c ("ARM: EXYNOS: add GPC4 bank instance") added a new gpio chip define and did tiny updates to the init code. So the conflict diff looks like hell, but it's actually a fairly simple change. * tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (34 commits) ARM: exynos: fix building with CONFIG_OF disabled ARM: EXYNOS: Add AUXDATA for i2c controllers ARM: dts: Update device tree source files for EXYNOS5250 ARM: EXYNOS: Add device tree support for interrupt combiner ARM: EXYNOS: Add irq_domain support for interrupt combiner ARM: EXYNOS: Remove a new bus_type instance for EXYNOS5 ARM: EXYNOS: update irqs for EXYNOS5250 SoC ARM: EXYNOS: Add pre-divider and fout mux clocks for bpll and mpll ARM: EXYNOS: add GPC4 bank instance ARM: EXYNOS: Redefine IRQ_MCT_L0,1 definition ARM: EXYNOS: Modify the GIC physical address for static io-mapping ARM: EXYNOS: Add watchdog timer clock instance pinctrl: SPEAr1310: Fix pin numbers for clcd_high_res SPEAr: Update MAINTAINERS and Documentation SPEAr13xx: Add defconfig SPEAr13xx: Add compilation support SPEAr13xx: Add dts and dtsi files pinctrl: Add SPEAr13xx pinctrl drivers pinctrl: SPEAr: Create macro for declaring GPIO PINS SPEAr13xx: Add common clock framework support ...
