Pull MIPS update from Ralf Baechle: "This is the MIPS update for 3.7. A fair chunk of them are platform updates to the Cavium Octeon SOC (which involves machine generated header files of considerable size), Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx platforms. Support for the commercial MIPS simulator MIPSsim has been removed as MIPS Technologies is shifting away from this product and Qemu is offering various more powerful platforms. The generic MIPS code can now also probe for no-execute / write-only TLB features implemented without the full SmartMIPS extension as permitted by the latest MIPS processor architecture. Lots of small changes to generic code." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (78 commits) MIPS: ath79: Fix CPU/DDR frequency calculation for SRIF PLLs MIPS: ath79: use correct fractional dividers for {CPU,DDR}_PLL on AR934x MIPS: BCM63XX: Properly handle mac address octet overflow MIPS: Kconfig: Avoid build errors by hiding USE_OF from the user.

First user is the boot rom aperture on armada XP since it is needed for SMP support. - New device tree bindings for peripherals such as gpio-fan, iconnect nand, mv_cesa and the above address decoder controller. - Some defconfig updates, mostly to enable new DT boards and a few drivers. - New drivers using the pincontrol subsystem for dove, kirkwood and mvebu - New clean gpio driver for mvebu" * tag 'soc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (98 commits) ARM: mvebu: fix build breaks from multi-platform conversion ARM: OMAP4460/4470: PMU: Enable PMU for OMAP4460/70 ARM: OMAP2+: PMU: Add runtime PM support ARM: OMAP4430: PMU: prepare to create PMU device via HWMOD ARM: OMAP2+: PMU: Convert OMAP2/3 devices to use HWMOD ARM: OMAP3: hwmod data: Add debugss HWMOD data ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU clockdomain idle problems ARM: OMAP: Add a timer attribute for timers that can interrupt the DSP hwrng: OMAP: remove SoC restrictions from driver registration ARM: OMAP: split OMAP1, OMAP2+ RNG device registration hwrng: OMAP: convert to use runtime PM hwrng: OMAP: store per-device data in per-device variables, not file statics ARM: OMAP2xxx: hwmod/CM: add RNG integration data ARM: OMAP2+: gpmc: minimal driver support ARM: OMAP2+: gpmc: Adapt to HWMOD ARM: OMAP2/3: hwmod data: add gpmc ARM: OMAP4: hwmod data: add mmu hwmod for ipu and dsp ARM: OMAP3: hwmod data: add mmu data for iva and isp ARM: OMAP: iommu: fix including iommu.h without IOMMU_API selected ARM: OMAP4: hwmod data: add missing HWMOD_NO_IDLEST flags to some PRCM IP blocks ...

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: "The first part of the media updates for Kernel 3.7. This series contain: - A major tree renaming patch series: now, drivers are organized internally by their used bus, instead of by V4L2 and/or DVB API, providing a cleaner driver location for hybrid drivers that implement both APIs, and allowing to cleanup the Kconfig items and make them more intuitive for the end user; - Media Kernel developers are typically very lazy with their duties of keeping the MAINTAINERS entries for their drivers updated. As now the tree is more organized, we're doing an effort to add/update those entries for the drivers that aren't currently orphan; - Several DVB USB drivers got moved to a new DVB USB v2 core; the new core fixes several bugs (as the existing one that got bitroted). Now, suspend/resume finally started to work fine (at least with some devices - we should expect more work with regards to it); - added multistream support for DVB-T2, and unified the API for DVB-S2 and ISDB-S. Backward binary support is preserved; - as usual, a few new drivers, some V4L2 core improvements and lots of drivers improvements and fixes. There are some points to notice on this series: 1) you should expect a trivial merge conflict on your tree, with the removal of Documentation/feature-removal-schedule.txt: this series would be adding two additional entries there. I opted to not rebase it due to this recent change; 2) With regards to the PCTV 520e udev-related breakage, I opted to fix it in a way that the patches can be backported to 3.5 even without your firmware fix patch. This way, Greg doesn't need to rush backporting your patch (as there are still the firmware cache and firmware path customization issues to be addressed there). I'll send later a patch (likely after the end of the merge window) reverting the rest of the DRX-K async firmware request, fully restoring its original behaviour to allow media drivers to initialize everything serialized as before for 3.7 and upper. 3) I'm planning to work on this weekend to test the DMABUF patches for V4L2. The patches are on my queue for several Kernel cycles, but, up to now, there is/was no way to test the series locally. I have some concerns about this particular changeset with regards to security issues, and with regards to the replacement of the old VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to GPU drivers change. The Overlay API allows direct PCI2PCI transfers from a media capture card into the GPU framebuffer, but its API is crappy. Also, the only existing X11 driver that implements it requires a XV extension that is not available anymore on modern drivers. The DMABUF can do the same thing, but with it is promising to be a properly-designed API. If I can successfully test this series and be happy with it, I should be asking you to pull them next week." * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (717 commits) em28xx: regression fix: use DRX-K sync firmware requests on em28xx drxk: allow loading firmware synchrousnously em28xx: Make all em28xx extensions to be initialized asynchronously [media] tda18271: properly report read errors in tda18271_get_id [media] tda18271: delay IR & RF calibration until init() if delay_cal is set [media] MAINTAINERS: add Michael Krufky as tda827x maintainer [media] MAINTAINERS: add Michael Krufky as tda8290 maintainer [media] MAINTAINERS: add Michael Krufky as cxusb maintainer [media] MAINTAINERS: add Michael Krufky as lg2160 maintainer [media] MAINTAINERS: add Michael Krufky as lgdt3305 maintainer [media] MAINTAINERS: add Michael Krufky as mxl111sf maintainer [media] MAINTAINERS: add Michael Krufky as mxl5007t maintainer [media] MAINTAINERS: add Michael Krufky as tda18271 maintainer [media] s5p-tv: Report only multi-plane capabilities in vidioc_querycap [media] s5p-mfc: Fix misplaced return statement in s5p_mfc_suspend() [media] exynos-gsc: Add missing static storage class specifiers [media] exynos-gsc: Remove <linux/version.h> header file inclusion [media] s5p-fimc: Fix incorrect condition in fimc_lite_reqbufs() [media] s5p-tv: Fix potential NULL pointer dereference error [media] s5k6aa: Fix possible NULL pointer dereference ...

Patch 6e20a0a4 "gpio: pcf857x: enable gpio_to_irq() support" added IRQ domain support to the pcf857x driver, but some configurations (e.g. davinci_all_defconfig) don't already enable CONFIG_IRQ_DOMAIN.

2012-09-22gpio: introduce gpio-mvebu driver for Marvell SoCsThomas Petazzoni
This driver aims at replacing the arch/arm/plat-orion/gpio.c driver, and is designed to be compatible with all Marvell EBU SoCs: Orion, Kirkwood, Dove, Armada 370/XP and Discovery. It has been successfully tested on Dove and Armada XP at the moment. Compared to the plat-orion driver, this new driver has the following added benefits: *) Support for Armada 370 and Armada XP *) It is integrated with the mvebu pinctrl driver so that GPIO pins are properly muxed, and the GPIO driver knows which GPIO pins are output-only or input-only. *) Properly placed in drivers/gpio *) More extensible mechanism to support platform differences. The plat-orion driver uses a simple mask-offset DT property, which works fine for Discovery MV78200 but not for Armada XP. The new driver uses different compatible strings to identify the different variants of the GPIO controllers.

2012-09-14gpio: gpio-ich: Share ownership of GPIO groupsJean Delvare
The ICH chips have their GPIO pins organized in 2 or 3 independent groups of 32 GPIO pins. It can happen that the ACPI BIOS wants to make use of pins in one group, preventing the OS to access these. This does not prevent the OS from accessing the other group(s). This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS wants to control GPIO 18 (group 1), while I (the OS) need to control GPIO 52 and 53 (group 2) for SMBus multiplexing. So instead of checking for ACPI resource conflict on the whole I/O range, check on a per-group basis, and consider it a success if at least one of the groups is available for the OS to use.

next/fixes-non-critical From "Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>: this is the 2nd version of this series whose goal is to make struct of_device_id.data const. Conceptually a driver must not modify the data contained there so making it const is the right thing. v1 of this series was sent with Message-id: 1342182734-321-1-git-send-email-y. Changes since then are: - powerpc fixes - several new consts that were found by Arnd that are possible after patch 19. Arnd suggested to take this series via arm-soc late for 3.6 in one go because patch 19 depends on the former patches but is a precondition to the latter and it fixes a few warnings. So getting it in via the respective maintainer trees would need a much bigger coordination effort. That means I prefer getting Acks over you taking the patch. Vinod Koul already took dmaengine: at_hdmac: add a few const qualifiers that is in next-20120723 as 7fd63ccdad72 now. Vinod, I don't follow your pull requests, but assuming you didn't let it already pull for 3.6 I suggest you drop it from your queue and I just take your Ack. This series was build tested for arm (all defconfigs) and powerpc (all defconfigs and an allyesconfig) and grep didn't find more issues. As before it introduces a warning in drivers/regulator/twl-regulator.c. This driver does modify its .of_match_table when a device is bound which doesn't fits the concept of independant devices. Arnd noticed another new warning in drivers/scsi/qlogicpti.c that isn't that easy to resolve, because the pointer to (now) const data is passed as first argument to scsi_host_alloc. To fix that properly struct Scsi_Host.hostt needs to get a const, too. Alternatively I could introduce a cast removing the const, but I don't like that. * 'ofdeviceiddata' of git://git.pengutronix.de/git/ukl/linux: (25 commits) dma: tegra: make data used as *of_device_id.data const can: mpc5xxx_can: make data used as *of_device_id.data const macintosh/mediabay: make data used as *of_device_id.data const i2c/mpc: make data used as *of_device_id.data const mfd/da9052: make i2c_device_id array const powerpc/fsl_msi: drop unneeded cast to non-const pointer gpio/gpio-omap: make platformdata used as *of_device_id.data const of: add const to struct *of_device_id.data dma: tegra: make tegra_dma.chip_data a pointer to const data watchdog/mpc8xxx: add a const qualifier powerpc/celleb_pci: add a const qualifier powerpc/fsl_msi: add a const qualifier powerpc/83xx: add a const qualifier macintosh/mediabay: add a const qualifier mmc/omap_hsmmc: add a const qualifier i2c/mpc: add a const qualifier i2c/i2c-omap: add a const qualifier gpio/mpc8xxx: add a const qualifier gpio/gpio-omap.c: add a const qualifier misc/atmel_tc: make atmel_tc.tcb_config member point to const data Signed-off-by: Arnd Bergmann <arnd@arndb.de> [olof: repulled a v3 version of the branch that rebased to add some more acked-bys and added one more patch on top for tegra] Signed-off-by: Olof Johansson <olof@lixom.net>

Until now the EXYNOS-SoC was the only Samsung-SoC supporting the GPIOs via the device tree. This patch implements dt-support for the s3c24xx arches. The controllers contain only 3 cells, as the underlying gpio controller does not support controlling the drive strength on a gpio level. Tested with the gpio-keys driver on a s3c2416 based machine.

2012-09-06gpio: exynos4: skip gpiolib registration if pinctrl driver is usedThomas Abraham
Pinctrl driver, when enabled, registers all the gpio pins and hence the registration of gpio pins by this driver can be skipped.
