git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC specific changes from Arnd Bergmann: "These changes are all to SoC-specific code, a total of 33 branches on 17 platforms were pulled into this. Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (480 commits) ARM: integrator: let pciv3 use mem/premem from device tree ARM: integrator: set local side PCI addresses right ARM: dts: Add pcie controller node for exynos5440-ssdk5440 ARM: dts: Add pcie controller node for Samsung EXYNOS5440 SoC ARM: EXYNOS: Enable PCIe support for Exynos5440 pci: Add PCIe driver for Samsung Exynos ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data ARM: keystone: Move CPU bringup code to dedicated asm file ARM: multiplatform: always pick one CPU type ARM: imx: select syscon for IMX6SL ARM: keystone: select ARM_ERRATA_798181 only for SMP ARM: imx: Synertronixx scb9328 needs to select SOC_IMX1 ARM: OMAP2+: AM43x: resolve SMP related build error dmaengine: edma: enable build for AM33XX ARM: edma: Add EDMA crossbar event mux support ARM: edma: Add DT and runtime PM support to the private EDMA API dmaengine: edma: Add TI EDMA device tree binding arm: add basic support for Rockchip RK3066a boards arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: Add basic clocks for Rockchip rk3066a SoCs ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates (part 2) from Arnd Bergmann: "These patches are all for Renesas shmobile, and depend on the earlier pinctrl updates. Remarkably, this adds support for three new SoCs: r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is for pinctrl (using the new subsystem) and for clocks (not yet using the common clock subsystem). The latter will have to get converted in one of the upcoming releases, but shmobile is not ready for that yet. The series also contains Renesas shmobile board changes, adding one board file for each of the three new SoCs. These boards are using a mix of classic and device-tree based probing, as there is still a lot of infrastructure in shmobile that has not been converted to DT yet. Once those are resolved to the degree that no board specific setup code is needed, they can get folded into the respective SoC setup files." * tag 'soc-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (78 commits) ARM: shmobile: use r8a7790 timer setup code on Lager ARM: shmobile: force enable of r8a7790 arch timer ARM: shmobile: Add second I/O range for r8a7790 PFC ARM: shmobile: bockw: enable network settings on bootargs ARM: shmobile: bockw: add SMSC ethernet support ARM: shmobile: R8A7778: add Ether support ARM: shmobile: bockw: enable SMSC ethernet on defconfig ARM: shmobile: r8a7778: add r8a7778_init_irq_extpin() ARM: shmobile: r8a7778: remove pointless PLATFORM_INFO() ARM: shmobile: mackerel: clean up MMCIF vs. SDHI1 selection ARM: shmobile: mackerel: add interrupt names for SDHI0 ARM: shmobile: mackerel: switch SDHI and MMCIF interfaces to slot-gpio ARM: shmobile: mackerel: remove OCR masks, where regulators are used ARM: shmobile: mackerel: SDHI resources do not have to be numbered ARM: shmobile: Initial r8a7790 Lager board support ARM: shmobile: APE6EVM LAN9220 support ARM: shmobile: APE6EVM PFC support ARM: shmobile: APE6EVM base support ARM: shmobile: kzm9g-reference: add ethernet support ARM: shmobile: add R-Car M1A Bock-W platform support ...

2013-04-03gpio: Renesas R-Car GPIO driver V3Magnus Damm
This patch is V3 of a GPIO driver for the R-Car series of SoCs from Renesas. This driver is designed to be reusable between multiple SoCs that share the same basic building block, but so far it has only been used on R-Car H1 (r8a7779). Each driver instance handles 32 GPIOs with individually maskable IRQs. The driver operates on a single I/O memory range and the 32 GPIOs are hooked up a single interrupt. In the case of R-Car H1 either external IRQ pins or GPIOs with interrupts can be used for on-board interupts. For external IRQs 4 pins are supported, and in the case of GPIO there are 202 GPIOS as 202 interrupts hooked up via 6 driver instances and to the GIC and the Cortex-A9 Quad. At this point this driver is interfacing as a regular platform device driver. In the future DT support will be submitted as an incremental feature patch.

2013-01-22gpio: devm_gpio_* support should not depend on GPIOLIBShawn Guo
Some architectures (e.g. blackfin) provide gpio API without requiring GPIOLIB support (ARCH_WANT_OPTIONAL_GPIOLIB). devm_gpio_* functions should also work for these architectures, since they do not really depend on GPIOLIB. Add a new option GPIO_DEVRES (enabled by default) to control the build of devres.c. It also removes the empty version of devm_gpio_* functions for !GENERIC_GPIO build from linux/gpio.h, and moves the function declarations from asm-generic/gpio.h into linux/gpio.h.

When building without device tree support (for the mv78x00 SoCs for example), the build failed because of_irq_count is undeclared. However mvebu-gpio is not designed to build without device tree support. So make it depends on OF_CONFIG, remove the #ifdef OF_CONFIG line and the platform_device_id.
