sound-fix-3.13-rc1abfe69dd · ·
sound fixes for 3.13-rc1 Two peaks in diffstat are for the audio EQ init of IDT codecs and the EMU2004 usb mixer addition, both of which are pretty device-specific, so safe to apply. The rest are a bunch of small fixes, most of them are regression fixes.

kvm-3.13-1e504c909 · ·
Here are the 3.13 KVM changes. There was a lot of work on the PPC side: the HV and emulation flavors can now coexist in a single kernel is probably the most interesting change from a user point of view. On the x86 side there are nested virtualization improvements and a few bugfixes. ARM got transparent huge page support, improved overcommit, and support for big endian guests. Finally, there is a new interface to connect KVM with VFIO. This helps with devices that use NoSnoop PCI transactions, letting the driver in the guest execute WBINVD instructions. This includes some nVidia cards on Windows, that fail to start without these patches and the corresponding userspace changes.

fbdev-3.133a41c5db · ·
fbdev changes for 3.13 Nothing particularly stands out in this pull request. The biggest part of the changes are cleanups. Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential dead lock" which hopefully fixes the fb locking issues reported by multiple persons. There are also a few commits that have changes to arch/arm/mach-at91 and arch/avr32, which have been acked by the maintainers.

devicetree-for-3.13c11eede6 · ·
DeviceTree updates for 3.13. This is a bit larger pull request than usual for this cycle with lots of clean-up. - Cross arch clean-up and consolidation of early DT scanning code. - Clean-up and removal of arch prom.h headers. Makes arch specific prom.h optional on all but Sparc. - Addition of interrupts-extended property for devices connected to multiple interrupt controllers. - Refactoring of DT interrupt parsing code in preparation for deferred probe of interrupts. - ARM cpu and cpu topology bindings documentation. - Various DT vendor binding documentation updates.

gpio-v3.13-199357127 · ·
GPIO bulk changes for the v3.13 development cycle - Merged the GPIO descriptor API from Alexandre Courbot. This is a first step toward trying to get rid of the global GPIO numberspace for the future. - Add an API so that driver can flag that a certain GPIO line is being used by a irqchip backend for generating IRQs, so that we can enforce checks, like not allowing users to switch that line to an output at runtime, since this makes no sense. Implemented corresponding calls in a few select drivers. - ACPI GPIO cleanups, refactorings and switch to using the descriptor-based interface. - Support for the TPS80036 Palmas GPIO variant. - A new driver for the Broadcom Kona GPIO SoC IP block. - Device tree support for the PCF857x driver. - A set of ARM GPIO refactorings with the goal of getting rid of a bunch of custom GPIO implementations from the arch/arm/* tree: - Move the IOP GPIO driver to the GPIO subsystem and fix all users to use the gpiolib API for accessing GPIOs. Delete the old custom GPIO implementation. - Delete the unused custom PXA GPIO implemention. - Convert all users of the IXP4 custom GPIO implementation to use gpiolib and delete the custom implementation. - Delete the custom Gemini GPIO implementation, also completely unused. - Various cleanups and renamings.

pinctrl-for-v3.13-19da83120 · ·
Main pin control pull request for the v3.13 cycle: - Blackfin ADI pin control driver, we move yet another architecture under this subsystem umbrella. - Incremental updates to the Renesas Super-H PFC pin control driver. New subdriver for the r8a7791 SoC. - Non-linear GPIO ranges from the gpiolib side of things, this enabled simplified device tree bindings by referring entire groups of pins on some pin controller to act as back-end for a certain GPIO-chip driver. - Add the Abilis TB10x pin control driver used on the ARC architecture. Also the corresponding GPIO driver is merged through this tree, so the ARC has full support for pins and GPIOs after this. - Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller instances. The i.MX1 and i.MX27 is an entirely new family (silicon) of controllers whereas i.MX50 is a variant of the previous supported controller. - Then the usual slew of fixes, cleanups and incremental updates.

sound-3.13-rc1a6bc732b · ·
sound updates for 3.13-rc1 There are no too intrusive changes in this update batch. The biggest LOC is found in the new DICE driver, and other small changes are scattered over the whole sound subtree (which is a common pattern). Below are highlights: - ALSA core: * Memory allocation support with genpool * Fix blocking in drain ioctl of compress_offload - HD-audio: * Improved AMD HDMI supports * Intel HDMI detection improvements * thinkpad_acpi mute-key integration * New PCI ID, New ALC255,285,293 codecs, CX20952 - USB-audio: * New buffer size management * Clean up endpoint handling codes - ASoC: * Further work on the dmaengine helpers, including support for configuring the parameters for DMA by reading the capabilities of the DMA controller which removes some guesswork and magic numbers from drivers. * A refresh of the documentation. * Conversions of many drivers to direct regmap API usage in order to allow the ASoC level register I/O code to be removed, this will hopefully be completed by v3.14. * Support for using async register I/O in DAPM, reducing the time taken to implement power transitions on systems that support it. - Fireiwre: DICE driver - Lots of small fixes for bugs reported by Coverity

regulator-v3.13d4d5cef6 · ·
regulator: Updates for v3.13 Lots of driver updates here plus some nice new core features, the main one being the first: - Enable support for providing a dummy regulator when we know that one must exist for the device to be functional. This makes it much easier to add regulator support to drivers since we don't require that the machine integration for all systems using the device be updated to provide regulators. - Substantial reduction in the amount of busy waiting done while waiting for enables to complete. - Allow MFDs to distribute regulator supplies to child devices so we don't have to expose the internal structure of MFDs outside of the driver. - Managed registeration for regulators.
