| * mfd: Commonize tps65910 regmap access through headerRhyland Klein2012-05-202-48/+26
| | | | | | | | | | | | | | | | | | | | This change removes the read/write callback functions in favor of common regmap accessors inside the header file. This change also makes use of regmap_read/write for single register access which maps better onto what this driver actually needs.

| * mfd: Support of hierachical interrupt for ab8500Michel JAOUEN2012-05-111-3/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Hierarchical interrupt is supported since ab8500 V2. However, it is not implemented in the ab8500-core driver. With the current implementation, when an ab9540 interrupt occurs, 17 Latch registers are read through i2c. With hierarchical interrupt implementation, there are only 4 i2c accesses.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the interrupts that come through this line should trigger wakeups: power button RTC alarm power available usb plug/unplug so mark the interrupt as a wakeup interrupt. This is particularly important for when the interrupt arrives during the late suspend phase. Without this setting it will be ignored.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The removal of mach/io.h from most ARM platforms also set the range of valid IO ports to be empty for most platforms when previously any 32 bit integer had been valid. This makes it impossible to add IO resources as the added range is smaller than that of the root resource for IO ports. Since we're not really using IO memory at all fix this by defining our own root resource outside the normal tree and make that the parent of all IO resources. This also ensures we won't conflict with read IO ports if we ever run on a platform which happens to use them.

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." Fix up conflicts in regmap (due to duplicate patches, with some further updates then having already come in from the regmap tree). Also some fairly trivial context conflicts in the imx and mcx soc drivers. * tag 'sound-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (280 commits) ALSA: snd-usb: fix stream info output in /proc ALSA: pcm - Add proper state checks to snd_pcm_drain() ALSA: sh: Fix up namespace collision in sh_dac_audio.
