2017-06-19ASoC: da7219: Fix HP detection procedure for all MCLK frequenciesAdam Thomson1-17/+36
Currently when HP detection procedure runs for certain MCLK frequencies, when PLL is bypassed, the procedure will incorrectly report Lineout instead of Headphones due to timing incosistencies. To avoid this problem, the PLL is temporarily enabled (if currently bypassed and MCLK present) to provide consistent timings for the procedure, regardless of MCLK frequency.

2016-10-28ASoC: da7219: Connect output enable register to DAIOUTStephen Barber1-1/+2
da7219 output (for headset capture) should be set to high-impedance when not in use, since it will otherwise interfere with output from other codecs attached to the same DAI.

2016-10-05ASoC: da7219: Improve pop/click performance for sensitive HPsAdam Thomson1-18/+121
Currently on some headsets slight pops can be heard during DAPM power-up/down. This can also be witnessed during the HP detect procedure. This patch addresses the issue by adjusting DAPM power sequencing slightly, the introduction of delays and use of minimum HP gain to avoid such noise artefacts.

2016-09-27ASoC: da7219: fix inappropriate condition statementTakashi Sakamoto1-1/+1
Sparse reports a below warning. sound/soc/codecs/da7219.c:804:57: warning: dubious: x & !y The line includes a condition statement; '(a < b) & !c'. Practically, the evaluated value of this statement equals to the value of '(a < b) && !c'. Although, it's not an usual way to use bitwise operations as logical operations to several conditions.

2016-09-26ASoC: da7219: Disable AAD if codec is not a wake-up sourceAdam Thomson1-13/+17
Currently if AAD is enabled in the device, during system suspend the feature remains, regardless of whether the codec is a wake-up source or not. This means some additional power is being used which is unnecessary, and can causes issues with some platforms' IRQ handlers where state changes during system suspend aren't captured. This patch updates the driver to disable AAD during suspend, if we're not a wake-up source, and then re-enables this on resume.

2016-09-26ASoC: da7219: Reset codec gracefully, if still activeAdam Thomson1-3/+27
Currently the reset code in i2c_probe only resets the AAD part of the device and not the entire codec. This patch updates the driver to resolve this and ensures that if the codec is still active from a previous boot then the audio paths are powered down prior to reset.

2016-08-08ASoC: codec duplicated callback function goes to component on da7219Kuninori Morimoto1-7/+8
codec driver and component driver has duplicated callback functions, and codec side functions are just copied to component side when register timing. This was quick-hack, but no longer needed. This patch moves these functions from codec driver to component driver. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-08-08ASoC: da7219: Make more efficient use of MCLK within driverAdam Thomson1-7/+11
Currently, if the driver has control of MCLK then it remains enabled as long as the codec is in STANDBY or above. The MCLK is only really required in STANDBY when a 3-pole jack is inserted and the HP detect procedure is required to run. This patch updates the code to enable/disable the MCLK when moving between the STANDBY and PREPARE bias level, and when a 3-pole jack is inserted and HP detection is required, thus saving power at all other times.

The PLL function was updated to disallow 32KHz in commit 501f72e9c520 ("ASoC: da7219: Remove support for 32KHz PLL mode"), but set_dai_sysclk() was missed and still permits it.

2016-01-05ASoC: da7219: Correct BCLK inversion for DSP DAI format modeAdam Thomson1-11/+37

Currently if bulk_enable() of supplies fails, the code still goes on to try and put the device into active state, and set expected IO voltage of the device. This doesn't really make sense so code now returns on bulk_enable() failure, with an error message. Also, to help with debug, failure to get supplies also provides an error message.
