git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6 Pull MFD bits from Samuel Ortiz: "We have support for a few new drivers: - Samsung s2mps11 - Wolfson Microelectronics wm5102 and wm5110 - Marvell 88PM800 and 88PM805 - TI twl6041 We also have our regular driver improvements: - Device tree and IRQ domain support for STE AB8500 - Regmap and devm_* API conversion for TI tps6586x - Device tree support for Samsung max77686 - devm_* API conversion for STE AB3100 Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910, tps65090, da9052 and twl-core." Fix up mostly trivial conflicts, with the exception of drivers/usb/host/ehci-omap.c in particular, which had some re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI: centralize controller initialization") that clashed with commit 2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues"). In particular, commit 2761a6394516 moved the usb_add_hcd() to the *middle* of the reset sequence, which clashes fairly badly with the reset sequence re-organization (although it could have been done inside the new omap_ehci_init() function). I left that part of commit 2761a6394516 just undone. * tag 'mfd-3.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (110 commits) mfd: Ensure AB8500 platform data is passed through db8500-prcmu to MFD Core mfd: Arizone core should select MFD_CORE mfd: Fix arizona-irq.c build by selecting REGMAP_IRQ mfd: Add debug trace on entering and leaving arizone runtime suspend mfd: Correct tps65090 cell names mfd: Remove gpio support from tps6586x core driver ARM: tegra: defconfig: Enable tps6586x gpio gpio: tps6586x: Add gpio support through platform driver mfd: Cache tps6586x register through regmap mfd: Use regmap for tps6586x register access. mfd: Use devm managed resources for tps6586x input: Add onkey support for 88PM80X PMIC mfd: Add support for twl6041 mfd: Fix twl6040 revision information mfd: Matches should be NULL when populate anatop child devices input: ab8500-ponkey: Create AB8500 domain IRQ mapping mfd: Add missing out of memory check for pcf50633 Documentation: Describe the AB8500 Device Tree bindings mfd: Add tps65910 32-kHz-crystal-input init mfd: Drop modifying mc13xxx driver's id_table in probe ...

None of the machines uses the gain ramp possibility for HS/HF. This code path is mostly unused and it does not reduces the pop noise on the output (it alters it to sound a bit different). The preferred method to reduce pop noise is to use ABE. Remove the gain ramp, and related features form the driver.

In order to support CODEC<->CODEC links remove the assumption that there is only a single CODEC on a DAI link by removing the use of the CODEC pointer in the rtd from the CODEC drivers.

2012-03-05Merge tag 'asoc-3.4' of ↵Takashi Iwai1-1/+1
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into topic/asoc This has been a very active release for ASoC, as well as the usual raft of bugfixes and driver updates there's quite a few framework enhancements. Most are either small or are laying the groundwork for user visible features (especially dynamic PCM), the most directly visible change is the dmaengine library. There's also a bunch of regmap API enhancements pulled into the tree so that either the framework or drivers can take advantage of the new features. Changes include: - Support for widgets not associated with a CODEC, an important part of the dynamic PCM framework. - A library factoring out the common code shared by dmaengine based DMA drivers contributed by Lars-Peter Clausen. This will save a lot of code and make it much easier to deploy enhancements to dmaengine. - Support for binary controls, used for providing runtime configuration of algorithm coefficients. - A new DAPM widget type for regulator supplies allowing drivers for devices that can power down unused supplies while active to do without any per-driver code. - DAPM widgets for DAIs, initially giving a speed boost for playback startup and shutdown and also the basis for CODEC<->CODEC DAI link support. - Support for specifying the number of significant bits on audio interfaces, useful for allowing applications to know how much effort to put into generating data for a larger sample format. - Conversion of the FSI driver used on some SH processors to DMAEngine. - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200.

2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen1-1/+1
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether.

2011-10-14ASoC: twl6040: Request core to inline the DAPM sequencePeter Ujfalusi1-0/+1
We need to have as less time between McPDM shutdown, and power down of the DAC on the twl6040 codec as possible. Request core to ignore the pmdown_time for the playback stream. Backround: with the McPDM protocol we are sendning not only the pure audio stream, but OMAP McPDM also transmits additional information (for example offset cancellation). If McPDM is stopped prior to the DAC this information will be not sent to the codec, which can result noise rendered by the twl6040 codec.

Selection between the two mode is implemented within the codec driver, the input/FF driver can only operate if the routing is set to "Input FF". Changing from "Input FF" to "Audio PDM" mode is protected as well: The switchin can only be done, if there is no running effect from the input/FF.
