IOMMU Updates for Linux v4.8 In the updates: * Big endian support and preparation for defered probing for the Exynos IOMMU driver * Simplifications in iommu-group id handling * Support for Mediatek generation one IOMMU hardware * Conversion of the AMD IOMMU driver to use the generic IOVA allocator. This driver now also benefits from the recent scalability improvements in the IOVA code. * Preparations to use generic DMA mapping code in the Rockchip IOMMU driver * Device tree adaption and conversion to use generic page-table code for the MSM IOMMU driver * An iova_to_phys optimization in the ARM-SMMU driver to greatly improve page-table teardown performance with VFIO * Various other small fixes and conversions

regulator: Updates for v4.8 A quiet regulator API release, a few new drivers and some fixes but nothing too notable. There will also be some updates for the PWM regulator coming through the PWM tree which provide much smoother operation when taking over an already running PWM regulator after boot using some new PWM APIs. - Support for configuration of the initial suspend state from DT. - New drivers for Mediatek MT6323, Ricoh RN5T567 and X-Powers AXP809.

ASoC: Updates for v4.8 Not really any framework work this time around (though we have seen one of the Analog Devices drivers move more to the clock API which is good to see) but rather a lot of new drivers: - Lots of updates for the Intel drivers, mostly board support and bug fixing, and to the NAU8825 driver. - Work on generalizing bits of simple-card to allow more code sharing with the Renesas rsrc-card (which can't use simple-card due to DPCM). - Removal of the Odroid X2 driver due to replacement with simple-card. - Support for several new Mediatek platforms and associated boards. - New drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504, Realtek RT5514 and Wolfson WM8758

gpio-v4.8-1224f9e6d · ·
This is the bulk of GPIO changes for the v4.8 kernel cycle. Core changes: - The big item is of course the completion of the character device ABI. It has now replaced and surpassed the former unmaintainable sysfs ABI: we can now hammer (bitbang) individual lines or sets of lines and read individual lines or sets of lines from userspace, and we can also register to listen to GPIO events from userspace. As a tie-in we have two new tools in tools/gpio: gpio-hammer and gpio-event-mon that illustrate the proper use of the new ABI. As someone said: the wild west days of GPIO are now over. - Continued to remove the pointless ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB Kconfig symbols. I'm patching hexagon, openrisc, powerpc, sh, unicore, ia64 and microblaze. These are either ACKed by their maintainers or patched anyways after a grace period and no response from maintainers. Some archs (ARM) come in from their trees, and others (x86) are still not fixed, so I might send a second pull request to root it out later in this merge window, or just defer to v4.9. - The GPIO tools are moved to the tools build system. New drivers: - New driver for the MAX77620/MAX20024. - New driver for the Intel Merrifield. - Enabled PCA953x for the TI PCA9536. - Enabled PCA953x for the Intel Edison. - Enabled R8A7792 in the RCAR driver. Driver improvements: - The STMPE and F7188x now supports the .get_direction() callback. - The Xilinx driver supports setting multiple lines at once. - ACPI support for the Vulcan GPIO controller. - The MMIO GPIO driver supports device tree probing. - The Acer One 10 is supported through the _DEP ACPI attribute. Cleanups: - A major cleanup of the OF/DT support code. It is way easier to read and understand now, probably this improves performance too. - Drop a few redundant .owner assignments. - Remove CLPS711x boardfile support: we are 100% DT.

sound fixes #2 for 4.7-final Now one more regression fix in addition to the previous pull request: two changes in the core part are for unusual error paths, while the rest are the regular HD-audio fixes and one USB-audio regression fix.
