2012-06-01ARM: ux500: Provide regulator support for SMSC911x via Device TreeLee Jones
This patch adds a fixed regulator for use by the SMSC911x Ethernet chip driver into the db8500 Device Tree. It also references other regulators required by the same device.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This is the first big chunk for 3.5 merges of sound stuff. There are a few big changes in different areas. First off, the streaming logic of USB-audio endpoints has been largely rewritten for the better support of "implicit feedback". If anything about USB got broken, this change has to be checked. For HD-audio, the resume procedure was changed; instead of delaying the resume of the hardware until the first use, now waking up immediately at resume. This is for buggy BIOS. For ASoC, dynamic PCM support and the improved support for digital links between off-SoC devices are major framework changes. Some highlights are below: * HD-audio - Avoid accesses of invalid pin-control bits that may stall the codec - V-ref setup cleanups - Fix the races in power-saving code - Fix the races in codec cache hashes and connection lists - Split some common codes for BIOS auto-parser to hda_auto_parser.c - Changed the PM resume code to wake up immediately for buggy BIOS - Creative SoundCore3D support - Add Conexant CX20751/2/3/4 codec support * ASoC - Dynamic PCM support, allowing support for SoCs with internal routing through components with tight sequencing and formatting constraints within their internal paths or where there are multiple components connected with CPU managed DMA controllers inside the SoC. - Greatly improved support for direct digital links between off-SoC devices, providing a much simpler way of connecting things like digital basebands to CODECs. - Much more fine grained and robust locking, cleaning up some of the confusion that crept in with multi-component. - CPU support for nVidia Tegra 30 I2S and audio hub controllers and ST-Ericsson MSP I2S controolers - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas Instruments LM49453. - Some regmap changes needed by the Tegra I2S driver. - mc13783 audio support. * Misc - Rewrite with module_pci_driver() - Xonar DGX support for snd-oxygen - Improvement of packet handling in snd-firewire driver - New USB-endpoint streaming logic - Enhanced M-audio FTU quirks and relevant cleanups - Increment the support of OSS devices to 256 - snd-aloop accuracy improvement There are a few more pending changes for 3.5, but they will be sent slightly later as partly depending on the changes of DRM."

2012-05-20mfd: Convert wm831x to irq_domainMark Brown
The modern idiom is to use irq_domain to allocate interrupts. This is useful partly to allow further infrastructure to be based on the domains and partly because it makes it much easier to allocate virtual interrupts to devices as we don't need to allocate a contiguous range of interrupt numbers. Convert the wm831x driver over to this infrastructure, using a legacy IRQ mapping if an irq_base is specified in platform data and otherwise using a linear mapping, always registering the interrupts even if they won't ever be used. Only boards which need to use the GPIOs as interrupts should need to use an irq_base. This means that we can't use the MFD irq_base management since the unless we're using an explicit irq_base from platform data we can't rely on a linear mapping of interrupts. Instead we need to map things via the irq_domain - provide a conveniencem function wm831x_irq() to save a small amount of typing when doing so. Looking at this I couldn't clearly see anything the MFD core could do to make this nicer. Since we're not supporting device tree yet there's no meaningful advantage if we don't do this conversion in one, the fact that the interrupt resources are used for repeated IP blocks makes accessor functions for the irq_domain more trouble to do than they're worth.

Also simplify things by not separately reseting the CODEC registers, this is a sufficiently infrequent operation that we can simply invalidate the entire cache when this happens.
