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 ...

2012-12-24ARM: delete struct sys_timerStephen Warren5-9/+5
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-10-07ARM: mv78xx0: mark mv78xx0_timer_init as __init_refokArnd Bergmann1-1/+1
The sys_timer init function is only called at __init time, so it's safe to mark mv78xx0_timer_init as __init_refok, which allows us to call orion_time_init without getting a link time warning.

2012-09-21arm: mach-mv78xx0: use plus instead of or for address definitionsThomas Petazzoni2-47/+47
Since we are going to use IOMEM() to define many base virtual addresses, we can no longer use binary or to define the individual register addresses ("binary or" arithmetic on pointers is not allowed). Instead, use the more conventional plus operator to do so. The binary or operators were actually not useful because the low-order bits of the base address were always zero, so the usage of the binary or operators was effectively identical to a plus operator.

From Rob Herring <robherring2@gmail.com>: This is the 2nd part of mach/io.h removals. This series removes io.h on platforms with PCI by creating a fixed virtual I/O mapping and a common __io() macro. This version has changed a bit to accommodate Tegra converting its PCIe host to a platform driver. Now the virtual space is only reserved during early boot before .map_io() is called. The mapping is not created until calling pci_ioremap_io which can be done at any point after vmalloc is initialized. I've gone back to fixed 64K windows for each PCI bus. This allows removing all the i/o resource setup from the individually platforms and placing it within the common ARM PCI code. I've only tested versatilepb under qemu (with the model hacked up to actually enable i/o space), so any testing is appreciated. iop3xx and mv78xx0 have some risk of breaking as the PCI bus addresses are moved to 0 from matching the cpu host bus addesss. * cleanup/io-pci: ARM: iop3xx: use fixed PCI i/o mapping ARM: mv78xx0: use fixed pci i/o mapping ARM: iop13xx: use fixed PCI i/o mapping iop13xx: use more regular PCI I/O space handling ARM: orion5x: use fixed PCI i/o mapping ARM: kirkwood: use fixed PCI i/o mapping ARM: dove: use fixed PCI i/o mapping ARM: footbridge: use fixed PCI i/o mapping ARM: shark: use fixed PCI i/o mapping ARM: integrator: remove trailing whitespace on pci_v3.c ARM: integrator: use fixed PCI i/o mapping ARM: tegra: use fixed PCI i/o mapping ARM: versatile: use fixed PCI i/o mapping ARM: move PCI i/o resource setup into common code ARM: Add fixed PCI i/o mapping i2c: iop3xx: use standard gpiolib functions i2c: iop3xx: clean-up trailing whitespace Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2012-05-13ARM: PCI: get rid of pci_std_swizzle()Russell King1-1/+0
Most PCI implementations use the standard PCI swizzle function, which handles the well defined behaviour of PCI-to-PCI bridges which can be found on cards (eg, four port ethernet cards.) Rather than having almost every platform specify the standard swizzle function, make this the default when no swizzle function is supplied. Therefore, a swizzle function only needs to be provided when there is something exceptional which needs to be handled. This gets rid of the swizzle initializer from 47 files, and leaves us with just two platforms specifying a swizzle function: ARM Integrator and Chalice CATS.

I just don't feel I have the time for PCI review and work that it deserves lately (I've taken on some other projects), and haven't been as responsive lately as I'd like, so I approached Bjorn asking if he'd like to manage things. He's going to give it a try, and I'm confident he'll do at least as well as I have in keeping the tree managed, patches flowing, and keeping things stable."

The patch "ARM: orion: Consolidate USB platform setup code.", commit 4fcd3f374a928081d391cd9a570afe3b2c692fdc broke USB on TS-7800 and other orion5x boards, because the wrong type of PHY was being passed to the EHCI driver in the platform data. Orion5x needs EHCI_PHY_ORION and all the others want EHCI_PHY_NA. Allow the mach- code to tell the generic plat-orion code which USB PHY enum to place into the platform data.

2012-02-09ARM: orion: Fix Orion5x GPIO regression from MPP cleanupAndrew Lunn1-113/+113
Patchset "ARM: orion: Refactor the MPP code common in the orion platform" broke at least Orion5x based platforms. These platforms have pins configured as GPIO when the selector is not 0x0. However the common code assumes the selector is always 0x0 for a GPIO lines. It then ignores the GPIO bits in the MPP definitions, resulting in that Orion5x machines cannot correctly configure there GPIO lines. The Fix removes the assumption that the selector is always 0x0. In order that none GPIO configurations are correctly blocked, Kirkwood and mv78xx0 MPP definitions are corrected to only set the GPIO bits for GPIO configurations. This third version, which does not contain any whitespace changes, and is rebased on v3.3-rc2.
