2011-04-27ASoC: Implement WM8962 ADC high pass filter configurationMark Brown

2011-04-26ASoC: Don't warn if the WM8962 SYSCLK FLL setting doesn't match realityMark Brown
When bringing up audio low power modes boards may configure SYSCLK before they actually start the FLL as we do much of the clocking setup prior to the power up sequence. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-04-26ASoC: Implement WM8962 DMIC supportMark Brown
DMIC support is automatically disabled when none of the GPIOs are set up to bring out the DMICCLK and DMICDAT pins at startup. Note that there's no support for controlling DMIC routing except the power control so the board DAPM configuration will need to manage DMIC enable and disable if analogue mics (eg, a headset) also exist.

2011-01-17ASoC: Avoid direct register cache access when setting defaultsMark Brown
Directly accessing the register cache means that we can't use anything except a flat register cache so use snd_soc_update_bits(). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

2010-12-28ASoC: codecs: wm8962: Fix register cache incoherencyLars-Peter Clausen
The multi-component patch(commit f0fba2ad1) moved the allocation of the register cache from the driver to the ASoC core. Most drivers where adjusted to this, but the wm8962 driver still uses its own register cache for its private functions, while functions from the ASoC core use the generic cache. Thus we end up with two from each other incoherent caches, which can lead to undefined behaviour. This patch fixes the issue by changing the wm8962 driver to use the generic register cache in its private functions.

2010-11-16ASoC: Fix incorrect kfree in wm8962_probe error pathAxel Lin
We allocated memory for wm8962 in wm8962_i2c_probe, and will free the memory in either wm8962_i2c_probe error path or wm8962_i2c_remove. Thus we should not call kfree(wm8962) in wm8962_probe, otherwise we have double free of wm8962.

2010-11-06ASoC: Decouple DAPM from CODECsLiam Girdwood
Decoupling Dynamic Audio Power Management (DAPM) from codec devices is required when developing ASoC further. Such as for other ASoC components to have DAPM widgets or when extending DAPM to handle cross-device paths. This patch decouples DAPM related variables from struct snd_soc_codec and moves them to new struct snd_soc_dapm_context that is used to encapsulate DAPM context of a device. ASoC core and API of DAPM functions are modified to use DAPM context instead of codec. This patch does not change current functionality and a large part of changes come because of structure and internal API changes. Core implementation is from Liam Girdwood <lrg@slimlogic.co.uk> with some minor core changes, codecs and machine driver conversions from Jarkko Nikula <jhnikula@gmail.com>.

2010-11-03ASoC: Use pm_wakeup_event() in WM8962 jack detectionMark Brown
Ensure that the system does not suspend while we process a WM8962 jack event by using pm_wakeup_event() to block the suspend while we're waiting for the jack to settle. Use a slightly longer timeout than the jack waits to allow for other stuff to take over and delays in scheduling.

2010-10-13ASoC: Add WM8962 microphone bias controlMark Brown
We unconditionally require SYSCLK since while only microphone detection specifically requires SYSCLK any actual use case would enable it via some other means but microphone detection may have nothing active other than the bias itself.

2010-10-11ASoC: Shrink code size for WM8962 register defaults tableMark Brown
Dramatically reduce the code size for the WM8962 register defaults table by switching to explicitly initialise only defined registers, relying on static defaulting to zero for the overwelming bulk of the register map. Similar treatement for the register access table will come later and will produce a similarly dramatic code size shrink.

2010-10-02ASoC: Put WM8962 GPIO2/3 into GPIO mode when configuring platform data tooMark Brown
GPIO2 and GPIO3 on the WM8962 are MFPs and need to be put into GPIO mode before the GPIO block can be used to control them. We're already doing this when used via gpiolib, factor out the code for use when setting static configurations via platform data as well.

2010-10-02ASoC: Implement interrupt based jack detectionMark Brown
Allow microphone detection on WM8962 to be performed using the interrupt signal, allowing the detection of both microphone presence and button presses with a signal singal from the CODEC to CPU. Currently a 250ms debounce time is applied to both short circuit and presence detection, this has not been optimised.

2010-09-30ASoC: Relax restrictions on WM8962 BCLK configurationMark Brown
The restrictions on configuring BCLK are overly cautious, other constraints in the system should ensure that reconfiguration is not possible when the device is sufficiently active to be unable to support reclocking.
