ASoC: Factor out shared code from WM8993 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.

ASoC: Improved wm_hubs headphone handling 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: Store DC offset correction for wm_hubs devices in class W mode 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.

ASoC: wm_hubs: Special case headphones for digital paths in more use cases The optimisations which we can do with caching the headphone DCS result in wm_hubs have only been enabled in cases where class W is enabled. However, there are more use cases which can benefit from the cache, especially with WM8994 series devices with their more advanced digital routing. Rather than keying off the class W information from the CODECs have a check in wm_hubs for a suitable path and use that to determine if we can deploy our headphone optimisations.
