2012-09-28ASoC: wm_hubs: Ensure volume updates are handled during class W startupMark Brown1-0/+5
In some circumstances we may need to flush volume updates to the device after switching to class W mode. Do this unconditionally to ensure that these situations are handled. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org
2012-08-22ASoC: wm_hubs: Allow configuration of MICBIAS power up delay via pdataMark Brown1-4/+31
Sometimes the analogue circuitry connected to the microphone needs some time to settle after power up. Allow systems to configure this delay in the platform data, the driver will then insert the required delay during power up of paths that involve the microphone.

2012-08-03ASoC: wm_hubs: Factor out DC servo readback codeMark Brown1-22/+43
It's currently only used in one place but another user will be added shortly and there's an argument it's clearer anyway. Also add support for readback in mode 1, though it's not currently used. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-05-01ASoC: wm_hubs: Cache multiple DCS offsetsMark Brown1-9/+65
Rather than invalidating the cached DCS value every time the headphone gain changes store multiple values, indexed by gain. This allows the optimisation we get from the cache to take effect more often. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-04-27ASoC: wm_hubs: Enable class W for output mixer pathsMark Brown1-21/+40
Class W can be used for any path where only data from the DAC is routed to the headphones. Currently we only enable it when the direct DAC to headphone path is used but it can also be enabled for paths that go via the output mixer providing the DAC is the only input to the output mixer. Implement support for this, including updates to the class W status when the output mixer configuration is changed. This also allows us to enable the DC servo optimisations for DAC to headphone paths where the output mixer is used. In general the direct DAC path is still preferred as this will offer better performance on most wm_hubs devices but these additional paths can simplify use case management.

2012-04-27ASoC: wm_hubs: Factor out class W managementMark Brown1-0/+59
Since the analogue portions of the checks for class W are the same over all the devices factor out these checks into wm_hubs and while we're at it also use wm_hubs_dac_hp_direct() to enable class W optimisations on more paths. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-04-27ASoC: wm_hubs: Special case headphones for digital paths in more use casesMark Brown1-6/+42
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.

2012-04-23ASoC: wm_hubs: Make sure we don't disable differential line outputsMark Brown1-6/+9
While we need to clean up unused single ended line outputs we don't want to do this if the outputs are in differential mode. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-03-19ASoC: wm_hubs: Don't actively manage LINEOUT_VMID_BUFMark Brown1-11/+5
It can just be enabled all the time with no impact. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-03-04ASoC: wm_hubs: Disable cache of the DC servo calibration for WM1811Mark Brown1-1/+1
The WM1811 DC servo is able to run much faster than previous devices so the benefit of skipping calibration is not useful. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-02-29ASoC: wm_hubs: Bomb out if we can't read back the DC servo resultMark Brown1-1/+1

2012-02-21ASoC: wm_hubs: Convert headphone driver to output driver widgetMark Brown1-3/+2

2012-02-11ASoC: wm_hubs: Improve single ended line output enable performanceMark Brown1-8/+105
The enable of the single ended line outputs on wm_hubs devices performs better if the output is enabled prior to starting VMID. Since inactive outputs are held at VMID anyway there is little cost to doing this for unused outputs. Add callbacks into wm_hubs and keep track of which outputs are really active so we can disable them once we're active. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-02-04ASoC: core: Add support for DAI and machine kcontrols.Liam Girdwood1-1/+1
Currently ASoC can only add kcontrols using codec and platform component device handles. It's also desirable to add kcontrols for DAIs (i.e. McBSP) and for SoC card machine drivers too. This allows the kcontrol to have a direct handle to the parent ASoC component DAI/SoC Card/Platform/Codec device and hence easily get it's private data. This change makes snd_soc_add_controls() static and wraps it in the folowing calls (card and dai are new) :- snd_soc_add_card_controls() snd_soc_add_codec_controls() snd_soc_add_dai_controls() snd_soc_add_platform_controls() This patch also does a lot of small mechanical changes in individual codec drivers to replace snd_soc_add_controls() with snd_soc_add_codec_controls(). It also updates the McBSP DAI driver to use snd_soc_add_dai_controls(). Finally, it updates the existing machine drivers that register controls to either :- 1) Use snd_soc_add_card_controls() where no direct codec control is required. 2) Use snd_soc_add_codec_controls() where there is direct codec control. In the case of 1) above we also update the machine drivers to get the correct component data pointers from the kcontrol (rather than getting the machine pointer via the codec pointer).

2012-01-31ASoC: wm_hubs: Push check for idle_bias_off out into driversMark Brown1-6/+0

2011-11-04ASoC: Disable thermal shutdown when not using speakers in wm_hubsMark Brown1-0/+3
The thermal shutdown support in wm_hubs devices is tied to the speaker drivers (which are the only high power subsystems within the device).
