* ASoC: Explicitly disable DC servo on WM hubs headphone powerdownMark Brown2010-07-201-0/+2
| | | | | Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
* ASoC: Reorder power down sequence for WM hubs devicesMark Brown2010-05-111-4/+4
| | | | | | | | | Disable the output stage prior to the delay stage rather than the other way around. Fixes merge issue with previous headphone output path corrections. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
* ASoC: Add additional WM hubs DC servo traceMark Brown2010-05-111-0/+4
| | | | | | | | Log the values we're getting back from the DC servo and the values we write to it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
* ASoC: Add indirection for CODEC private dataMark Brown2010-04-171-3/+3
| | | | | | | | | | | | | | | | 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.

* ASoC: Don't use DCS_DATAPATH_BUSY for WM hubs devicesMark Brown2010-04-051-23/+15
| | | | | | | | | | | | 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.

* ASoC: Don't do runtime wm_hubs DC servo updates if using offset correctionMark Brown2010-04-051-0/+6
| | | | | | | | | 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>
* ASoC: Support second DC servo readback method for wm_hubsMark Brown2010-04-051-11/+30
| | | | | | | | | | | 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>
* ASoC: Avoid wraparound in wm_hubs DC servo correctionMark Brown2010-04-051-2/+4
| | | | | | | | If the correction wraps around then a substantial offset would be introduced. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
* ASoC: Bail out of wm_hubs DC servo if calibration failsMark Brown2010-03-191-1/+1
| | | | | | | | We're keeping track of the number of times we've iterated but never actually using this to bail out if the chip looks stuck. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
* ASoC: Improved wm_hubs headphone handlingMark Brown2010-02-011-26/+116
| | | | | | | | | | | | | | | 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>
* ASoC: Use BIAS_OFF when idle for wm_hubs devicesMark Brown2010-01-211-0/+6

* ASoC: Remove duplicate ADC/DAC widgets from wm_hubs.cMark Brown2009-08-181-6/+0
| | | | | | | These need to be in the CODEC since the DAIs supported by the CODECs aren't static. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Factor out shared code from WM8993Mark Brown2009-08-131-0/+758
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.
