2011-04-11ASoC: Fix output PGA enabling in wm_hubs CODECsMark Brown
The output PGA was not being powered up in headphone and speaker paths, removing the ability to offer volume control and mute with the output PGA. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Cc: stable@kernel.org
2011-02-18ASoC: Hook wm_hubs micbiases up to CLK_SYSMark Brown
The microphone detection functionality requires a clock to work. In any non-detection case where the MICBIAS is enabled CLK_SYS will be needed anyway so there is no negative impact on power consumption. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2010-11-27ASoC: Use DC servo startup mode when not doing DCS correctionMark Brown
Devices which do not have a DCS correction applied can use the explicit DC servo startup mode for optimal startup performance. This most immediately affects the WM8958. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

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>.

2010-10-28ASoC: Store DC offset correction for wm_hubs devices in class W modeMark Brown
Providing the analogue configuration of the output path remains the same the DC offset corrected by the DC servo will remain identical so we can skip the callibration, reducing the startup time for the headphone output. Implement this for the wm_hubs devices as has been done for several other CODECs. Don't do this if we have any analogue paths enabled since offsets may be being introduced by the analogue paths which could vary outside the control of the driver.

2010-04-17ASoC: Add indirection for CODEC private dataMark Brown
One of the features of the multi CODEC work is that it embeds a struct device in the CODEC to provide diagnostics via a sysfs class rather than via the device tree, at which point it's much better to use the struct device private data rather than having two places to store it. Provide an accessor function to allow this change to be made more easily, and update all the CODEC drivers are updated. To ensure use of the accessor the private data structure member is renamed, meaning that if code developed with older an older core that still uses private_data is merged it will fail to build.

2010-04-05ASoC: Don't use DCS_DATAPATH_BUSY for WM hubs devicesMark Brown
The DCS_DATAPATH_BUSY bit used to monitor the completion of DC servo operations has been deprecated and with some more recente revisions may perform incorrectly, especially when only analogue bypass paths are in use. Switch to using readback from the DC servo command register instead, which is supported for all devices. Without this unacceptably long timeouts may be observed in some circumstances.

2010-04-05ASoC: Don't do runtime wm_hubs DC servo updates if using offset correctionMark Brown
If we need to offset correct the DC servo then don't use runtime recalibration since that is likely to introduce further offsets which will be evident on powerdown. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
2010-04-05ASoC: Support second DC servo readback method for wm_hubsMark Brown
More recent Wolfson hubs devices add the ability to read back the DC servo calibration information from the register used to write offsets, and later still ones remove the old readback registers. Add support for the new scheme, and use it for WM8994 device revisions that support it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

2010-03-19ASoC: Bail out of wm_hubs DC servo if calibration failsMark Brown

2010-02-01ASoC: Improved wm_hubs headphone handlingMark Brown
Perform DC servo offset calibration using a series update sequence rather than startup update sequence, tuning the configuration of the WM8993 DC servo to make best use of this. Also introduce currently unused data allowing us to correct for any systematic errors in the DC servo calibration results and an alternative startup path for the headphone output which performs better with some chip revisions. The alternative setup sequence is enabled for WM8993. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

2009-08-13ASoC: Factor out shared code from WM8993Mark Brown
The WM8993 analogue control is shared with other devices in the same product line. Since this is a very substantial proportion of the driver move the definitions of these controls into a new wm_hubs module which allows them to be shared between the two.
