Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc-specific updates from Olof Johansson: "Most notable here is probably the addition of basic support for the BCM2835, an SoC used in some of the Roku 2 players as well as the much-hyped Raspberry Pi, cleaned up and contributed by Stephen Warren. It's still early days on mainline support, with just the basics working. But it has to start somewhere! Beyond that there's some conversions of clock infrastructure on tegra to common clock, misc updates for several other platforms, and OMAP now has its own bus (under drivers/bus) to manage its devices through. This branch adds two new directories outside of arch/arm: drivers/irqchip for new irq controllers, and drivers/bus for the above OMAP bus. It's expected that some of the other platforms will migrate parts of their platforms to those directories over time as well." Fix up trivial conflicts with the clk infrastructure changes. * tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (62 commits) ARM: shmobile: add new __iomem annotation for new code ARM: LPC32xx: Support GPI 28 ARM: LPC32xx: Platform update for devicetree completion of spi-pl022 ARM: LPC32xx: Board cleanup irqchip: fill in empty Kconfig ARM: SAMSUNG: Add check for NULL in clock interface ARM: EXYNOS: Put PCM, Slimbus, Spdif clocks to off state ARM: EXYNOS: Add bus clock for FIMD ARM: SAMSUNG: Fix HDMI related warnings ARM: S3C24XX: Add .get_rate callback for "camif-upll" clock ARM: EXYNOS: Fix incorrect help text ARM: EXYNOS: Turn off clocks for NAND, OneNAND and TSI controllers ARM: OMAP: AM33xx hwmod: fixup SPI after platform_data move MAINTAINERS: add an entry for the BCM2835 ARM sub-architecture ARM: bcm2835: instantiate console UART ARM: bcm2835: add stub clock driver ARM: bcm2835: add system timer ARM: bcm2835: add interrupt controller driver ARM: add infra-structure for BCM2835 and Raspberry Pi ARM: tegra20: add CPU hotplug support ...
