2013-06-11ARM: OMAP2+: add user and fifo info to mailbox platform dataSuman Anna1-0/+5
The different generations of OMAP2+ SoCs have almost the same mailbox IP, but the IP has configurable parameters for number of users (interrupts it can generate out towards processors) and number of fifos (the base unidirectional h/w communication channel). This data cannot be read from any registers, and so has been added to the platform data. This data together with the interrupt-type configuration can be used in properly figuring out the number of registers to save and restore in the OMAP mailbox driver code.

2013-06-11phy-rcar-usb: add R8A7778 supportSergei Shtylyov1-1/+3
The driver currently only supports R8A7779 SoC. Compared to it, R8A7778 USB-PHY has extra register range containing two high-speed signal quality characteristic control registers which should be set up during USB-PHY startup depending on whether a ferrite bead is in use or not. So, we now handle an optional second memory range in the driver's probe method, add the 'ferrite_bead' field to the driver's platform data, and add an extra (optional) step to the USB-PHY startup routine which sets up the extended registers. Also mark in the driver's Kconfig section that R8A7778 is now supported and generally clarify that section, uppercasing the word "phy" and also changing the module name that got lost in the big driver rename, while at it... The patch has been tested on the Marzen and BOCK-W boards.

Currently the driver hard-codes USBPCTRL0 register to 0.

2013-06-04gpio-rcar: Add RCAR_GP_PIN macroLaurent Pinchart1-0/+2
Pins are numbered in the R-Car family documentation using a bank number and a pin number in the bank. As the Linux pin number space is linear, we need to flatten this by multiplying the bank number by 32 and adding the pin number. The resulting number bear no directly visible relationship to the documentation, making it error-prone. Add a RCAR_GP_PIN macro to convert from the documentation pin number space to the linear Linux space.

As hardware support for this feature is not universal for all SoCs a flag, has_both_edge_trigger, has been added to the platform data of the driver to allow this feature to be enabled.

At this moment in time the memcpy channels which can be used by the D40 are fixed, as each supported platform in Mainline uses the same ones. However, platforms do exist which don't follow this convention, so these will need to be tailored. Fortunately, these platforms will be DT only, so this change has very little impact on platform data.

2013-06-04dmaengine: ste_dma40: Convert data_width from register bit format to valueLee Jones1-8/+1
When a DMA client requests and configures a DMA channel, it requests data_width in Bytes. The DMA40 driver then swiftly converts it over to the necessary register bit value. Unfortunately, for any subsequent calculations we have to shift '1' by the bit pattern (1 << data_width) times to make any sense of it. This patch flips the semantics on its head and only converts the value to its respective register bit pattern when writing to registers. This way we can use the true data_width (in Bytes) value.

2013-05-19SERIAL: OMAP: Remove the slave idle handling from the driverSantosh Shilimkar1-2/+0
UART IP slave idle handling now taken care by runtime pm backend(hwmod layer) so remove the hackery from the driver. As discussed on the list, in future if dma mode needs to be brought back to this driver, UART sysc handling needs to be updated in framework such a way that no-idle/force idle profile can be supported. Given the broken dma mode for OMAP uarts, its very unlikely.

2013-05-14ACPI / LPSS: register clock device for Lynxpoint DMA properlyRafael J. Wysocki1-0/+5
The DMA controller in Lynxpoint is enumerated as a regular ACPI device now. To work properly it is using the LPSS root clock as a functional clock. That's why we have to register the clock device accordingly to the ACPI ID of the DMA controller. The acpi_lpss.c module is responsible to do the job. This patch also removes hardcoded name of the DMA device in clk-lpt.c and the name of the root clock in acpi_lpss.c. Signed-off-by: Rafael J.

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 ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver changes from Olof Johansson: "This is a rather large set of patches for device drivers that for one reason or another the subsystem maintainer preferred to get merged through the arm-soc tree. There are both new drivers as well as existing drivers that are getting converted from platform-specific code into standalone drivers using the appropriate subsystem specific interfaces. In particular, we can now have pinctrl, clk, clksource and irqchip drivers in one file per driver, without the need to call into platform specific interface, or to get called from platform specific code, as long as all information about the hardware is provided through a device tree. Most of the drivers we touch this time are for clocksource. Since now most of them are part of drivers/clocksource, I expect that we won't have to touch these again from arm-soc and can let the clocksource maintainers take care of these in the future. Another larger part of this series is specific to the exynos platform, which is seeing some significant effort in upstreaming and modernization of its device drivers this time around, which unfortunately is also the cause for the churn and a lot of the merge conflicts. There is one new subsystem that gets merged as part of this series: the reset controller interface, which is a very simple interface for taking devices on the SoC out of reset or back into reset. Patches to use this interface on i.MX follow later in this merge window, and we are going to have other platforms (at least tegra and sirf) get converted in 3.11. This will let us get rid of platform specific callbacks in a number of platform independent device drivers." * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (256 commits) irqchip: s3c24xx: add missing __init annotations ARM: dts: Disable the RTC by default on exynos5 clk: exynos5250: Fix parent clock for sclk_mmc{0,1,2,3} ARM: exynos: restore mach/regs-clock.h for exynos5 clocksource: exynos_mct: fix build error on non-DT pinctrl: vt8500: wmt: Fix checking return value of pinctrl_register() irqchip: vt8500: Convert arch-vt8500 to new irqchip infrastructure reset: NULL deref on allocation failure reset: Add reset controller API dt: describe base reset signal binding ARM: EXYNOS: Add arm-pmu DT binding for exynos421x ARM: EXYNOS: Add arm-pmu DT binding for exynos5250 ARM: EXYNOS: Enable PMUs for exynos4 irqchip: exynos-combiner: Correct combined IRQs for exynos4 irqchip: exynos-combiner: Add set_irq_affinity function for combiner_irq ARM: EXYNOS: fix compilation error introduced due to common clock migration clk: exynos5250: Fix divider values for sclk_mmc{0,1,2,3} clk: exynos4: export clocks required for fimc-is clk: samsung: Fix compilation error clk: tegra: fix enum tegra114_clk to match binding ...
