Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson: "This branch contains mostly additions and changes to platform enablement and SoC-level drivers. Since there's sometimes a dependency on device-tree changes, there's also a fair amount of those in this branch. Pieces worth mentioning are: - Mbus driver for Marvell platforms, allowing kernel configuration and resource allocation of on-chip peripherals. - Enablement of the mbus infrastructure from Marvell PCI-e drivers. - Preparation of MSI support for Marvell platforms. - Addition of new PCI-e host controller driver for Tegra platforms - Some churn caused by sharing of macro names between i.MX 6Q and 6DL platforms in the device tree sources and header files. - Various suspend/PM updates for Tegra, including LP1 support. - Versatile Express support for MCPM, part of big little support. - Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7) - OMAP2+ support for DRA7, a new Cortex-A15-based SoC. The code that touches other architectures are patches moving MSI arch-specific functions over to weak symbols and removal of ARCH_SUPPORTS_MSI, acked by PCI maintainers" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (266 commits) tegra-cpuidle: provide stub when !CONFIG_CPU_IDLE PCI: tegra: replace devm_request_and_ioremap by devm_ioremap_resource ARM: tegra: Drop ARCH_SUPPORTS_MSI and sort list ARM: dts: vf610-twr: enable i2c0 device ARM: dts: i.MX51: Add one more I2C2 pinmux entry ARM: dts: i.MX51: Move pins configuration under "iomuxc" label ARM: dtsi: imx6qdl-sabresd: Add USB OTG vbus pin to pinctrl_hog ARM: dtsi: imx6qdl-sabresd: Add USB host 1 VBUS regulator ARM: dts: imx27-phytec-phycore-som: Enable AUDMUX ARM: dts: i.MX27: Disable AUDMUX in the template ARM: dts: wandboard: Add support for SDIO bcm4329 ARM: i.MX5 clocks: Remove optional clock setup (CKIH1) from i.MX51 template ARM: dts: imx53-qsb: Make USBH1 functional ARM i.MX6Q: dts: Enable I2C1 with EEPROM and PMIC on Phytec phyFLEX-i.MX6 Ouad module ARM i.MX6Q: dts: Enable SPI NOR flash on Phytec phyFLEX-i.MX6 Ouad module ARM: dts: imx6qdl-sabresd: Add touchscreen support ARM: imx: add ocram clock for imx53 ARM: dts: imx: ocram size is different between imx6q and imx6dl ARM: dts: imx27-phytec-phycore-som: Fix regulator settings ARM: dts: i.MX27: Remove clock name from CPU node ...
