Pull ARM SoC device tree changes from Arnd Bergmann: "These changes from 30 individual branches for the most part update device tree files, but there are also a few source code changes that have crept in this time, usually in order to atomically move over a driver from using hardcoded data to DT probing. A number of platforms change their DT files to use the C preprocessor, which is causing a bit of churn, but that is hopefully only this once" * tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (372 commits) ARM: at91: dt: rm9200ek: add spi support ARM: at91: dt: rm9200: add spi support ARM: at91/DT: at91sam9n12: add SPI DMA client infos ARM: at91/DT: sama5d3: add SPI DMA client infos ARM: at91/DT: fix SPI compatibility string ARM: Kirkwood: Fix the internal register ranges translation ARM: dts: bcm281xx: change comment to C89 style ARM: mmc: bcm281xx SDHCI driver (dt mods) ARM: nomadik: add the new clocks to the device tree clk: nomadik: implement the Nomadik clocks properly ARM: dts: omap5-uevm: Provide USB Host PHY clock frequency ARM: dts: omap4-panda: Fix DVI EDID reads ARM: dts: omap4-panda: Add USB Host support arm: mvebu: enable mini-PCIe connectors on Armada 370 RD ARM: shmobile: irqpin: add a DT property to enable masking on parent ARM: dts: AM43x EPOS EVM support ARM: dts: OMAP5: Add bandgap DT entry ARM: dts: AM33XX: Add pinmux configuration for CPSW to am335x EVM ARM: dts: AM33XX: Add pinmux configuration for CPSW to EVMsk ARM: dts: AM33XX: Add pinmux configuration for CPSW to beaglebone ...

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 ...

drivers: bus: add a new driver for WEIM

2013-06-17T08:04:28Z

The WEIM(Wireless External Interface Module) works like a bus. You can attach many different devices on it, such as NOR, onenand. In the case of i.MX6q-sabreauto, the NOR is connected to WEIM. This patch also adds the devicetree binding document. The driver only works when the devicetree is enabled. Signed-off-by: Huang Shijie Acked-by: Sascha Hauer Signed-off-by: Shawn Guo

bus: mvebu-mbus: Use pr_fmt

In order to clean message printing, we replace pr_info with pr_fmt. This is purely cosmetic change, with the sole purpose of making the code a bit more readable. Signed-off-by: Ezequiel Garcia Acked-by: Thomas Petazzoni Signed-off-by: Jason Cooper

drivers/bus: arm-cci: fix combined ARMv6+v7 build

2013-06-03T13:26:08Z

When we build a kernel with support for both ARMv6 and ARMv7, gas is trying to be helpful by pointing out that the arm-cci driver would not work on ARMv6: /tmp/ccu1LDeU.s: Assembler messages: /tmp/ccu1LDeU.s:450: Error: selected processor does not support ARM mode `wfi ' /tmp/ccu1LDeU.s:451: Error: selected processor does not support ARM mode `wfe ' make[4]: *** [drivers/bus/arm-cci.o] Error 1 We know that the driver will only be used on ARMv7, hence we can annotate the inline assembly listing to allow those instructions.

ARM: OMAP2+: Remove omap4 ocp2scp pdata

2013-05-30T20:09:31Z

This is omap4+ only and no longer needed as omap4+ can be booted using device tree. Also remove the related pdata handling from the driver and the now unneeded platform_data/omap_ocp2scp.h.

drivers/bus: arm-cci: function to enable CCI ports from early boot code

2013-05-29T19:50:34Z

This provides cci_enable_port_for_self(). This is the counterpart to cci_disable_port_by_cpu(self). This is meant to be called from the MCPM machine specific power_up_setup callback code when the appropriate affinity level needs to be initialized. The code therefore has to be position independent as the MMU is still off and it cannot rely on any stack space. Signed-off-by: Nicolas Pitre Reviewed-by: Dave Martin

drivers: bus: add ARM CCI support

2013-05-29T19:50:34Z

On ARM multi-cluster systems coherency between cores running on different clusters is managed by the cache-coherent interconnect (CCI). It allows broadcasting of TLB invalidates and memory barriers and it guarantees cache coherency at system level through snooping of slave interfaces connected to it. This patch enables the basic infrastructure required in Linux to handle and programme the CCI component. Non-local variables used by the CCI management functions called by power down function calls after disabling the cache must be flushed out to main memory in advance, otherwise incoherency of those values may occur if they are sitting in the cache of some other CPU when power down functions execute. Driver code ensures that relevant data structures are flushed from inner and outer caches after the driver probe is completed. CCI slave port resources are linked to set of CPUs through bus masters phandle properties that link the interface resources to masters node in the device tree. Documentation describing the CCI DT bindings is provided with the patch. Signed-off-by: Lorenzo Pieralisi Signed-off-by: Nicolas Pitre
