* ASoC: Provide debug log of accessory status on WM8958Mark Brown2016-04-301-0/+2
| | | | Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Enhance default WM8958 microphone detectionMark Brown2016-04-302-11/+111
| | | | | | | | Actively manage the detection rate for microphones with WM8958, providing improved power consumption and maximising the benefit from the hardware debounce. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Put WM8958 and WM1811 MICBIAS into bypass mode when no audioMark Brown2016-04-301-1/+39
| | | | | | | When we don't have any active audio we can put the microphone biases into bypass mode to save power at the expense of performance. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Ensure SYSCLK is enabled for WM8958 accessory detectionMark Brown2016-04-301-0/+3
| | | | | | | | Ensure SYSCLK is enabled while running accessory detection on WM8958. It is always required so there is no sense in requiring machine drivers to individually do this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Supply dcs_codes for newer WM1811 revisionsMark Brown2016-04-301-0/+2
| | | | | | Based on initial data. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Ensure we get an impedence reported for WM8958 jack detectMark Brown2016-04-301-11/+26
| | | | | | | | | Occasionally we may see an accessory reported before we have a stable impedance for the accessory. If this happens then reread the status in order to ensure that the handler can take the appropriate action for the status change. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Don't use wm8994->control_data when requesting IRQsMark Brown2016-04-301-2/+2
| | | | | | | | The field is no longer initialised so this will crash if running on wm8958. Reported-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Update WM1811 DCS codes for latest evaluation resultsMark Brown2016-04-301-2/+2
| | | | | | | | Evaluation of larger quantities of material has provided new DCS codes values to be applied for WM1811. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
* ASoC: Remove impossible case from wm8994_hw_paramsAxel Lin2016-04-301-10/+0
| | | | | | | | We set hw_params callback for wm8994_aif3_dai_ops to wm8994_aif3_hw_params. Thus no need to check wm8994-aif3 in wm8994_hw_params. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: wm8994: Slightly optimize configure_clockAxel Lin2016-04-301-7/+4
| | | | | | | | | | snd_soc_update_bits() will only write new register value if the old value is different from the new value. In additional, snd_soc_update_bits() returns 0 for no change. No need to read WM8994_CLOCKING_1 register before calling snd_soc_update_bits(). Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Add WM1811 supportMark Brown2016-04-301-5/+78
| | | | | | | | The WM1811 is mostly register compatible with the WM8994 and WM8958, providing a high performance audio hub CODEC in a small form factor suitable for ultra compact system designs. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* ASoC: Implement WM8994 thermal warning and shutdown interrupt supportMark Brown2016-04-301-0/+26
| | | | | | | ALSA doesn't really have good mechanisms for dealing with these so we just log them - the hardware already has automatic shutdown support. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Add WM8958 noise gate supportMark Brown2016-04-302-6/+44

* ASoC: Disable pulls on WM8994 AIF2 when starting itMark Brown2016-04-301-0/+16
| | | | | | | | | | Pull control is availalbe for WM8994 AIF2, generally disabled as part of the GPIO configuration in order to save power after system startup. As on newer devices in the series there is no GPIO functionality on these pins this will happen less naturally so have the driver disable the pulls as the AIF is probed. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Disable WM8994 VMID for digital only pathsMark Brown2016-04-302-56/+129
| | | | | | | | | | | On WM8994 class devices only the analogue portions of the CODEC require VMID so when running digital only paths we can leave VMID disabled. On some earlier devices the FLL uses VMID so we don't use DAPM reference counting alone, we maintain an internal reference count which is also enabled and disabled by the FLL startup.

* ASoC: Handle failed WM8994 FLL lock waitsMark Brown2016-04-301-0/+3
| | | | | | | | Try the completion before we start the FLL so that if an interrupt was delayed long enough for us to miss it we don't wait for the completion it signalled. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Log WM8994 FIFO errors from the interruptMark Brown2016-04-301-0/+14
| | | | | | | We should spot them anyway on state changes but logging them gives us better time information about when the misconfiguration happened. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Don't warn on low WM8994/58 AIFnCLKsMark Brown2016-04-301-4/+0
| | | | | | We can have valid but very low clocks in accessory detection modes. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Use WM8994 FLL lock interruptMark Brown2016-04-302-1/+42
| | | | | | | If we have interrupts then wait for the FLL lock interrupt rather than using dead reckoning when waiting for the FLL to start. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* ASoC: Add missing break in WM8994 probeMark Brown2016-04-301-0/+1

* ASoC: wm_hubs: Enable line out VMID buffer for single ended line outputsMark Brown2016-04-301-0/+2
| | | | | | | | For optimal performance the single ended line outputs require that the line output VMID buffer be enabled. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org
* ASoC: Disable thermal shutdown when not using speakers in wm_hubsMark Brown2016-04-301-0/+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). Ensure minimal current usage when the thermal shutdown support is not required by disabling the circuit when the speaker drivers are powered down. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Add VMID widget for wm_hubs devicesMark Brown2016-04-303-0/+23
| | | | | | | | | Currently this does not actually do anything, it is being introduced in order to facilitate additional power optimisations for current generation devices. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
* ASoC: Support separate left and right channel dcs_codes valuesMark Brown2016-04-304-9/+13

* ASoC: Implement new DC servo readback mode for late WM8994 revisionsMark Brown2016-04-302-5/+17
| | | | | | | | | Later WM8994 devices implement a new DC servo readback mode with the register used to access the offset moved to register 0x59. Implement support for this and enable it on the appropriate devices. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
* ASoC: Disable wm_hubs periodic DC servo updateMark Brown2016-04-301-2/+1
| | | | | | | | | This does not function correctly in all circumstances so disable the periodic updates unconditionally for stable; a future patch will reenable where appropriate. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

* ASoC: Implement DC servo completion IRQ handling for wm_hubs devicesMark Brown2016-04-302-5/+37
| | | | | | | | The individual devices should set the flag dcs_done_irq in the hubs shared data structure to indicate that they will flag the interrupt by calling wm_hubs_dcs_done(). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Use late enable handling for direct voice, speaker and headphoneMark Brown2016-04-303-13/+22
