2017-10-26ASoC: sgtl5000: Remove leading zero from '@0a' notationMarco Franchi1-1/+1
Improve the binding example by removing the leading 0 from '@0a' notation, which fixes the following build warning: Warning (unit_address_format): Node /sgtl5000@0a unit name should not have leading 0s Signed-off-by: Marco Franchi <marco.franchi@nxp.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-04-10ASoC: sgtl5000: Allow LRCLK pad drive strength to be changedFabio Estevam1-0/+9
Introduce the "lrclk-strength" property to allow LRCLK pad drive strength to be changed via device tree. When running a stress playback loop test on a mx6dl wandboard channel swap can be noticed on about 10% of the times. While debugging this issue I noticed that when probing the SGTL5000 LRCLK pin with the scope the swap did not happen. After removing the probe the swap started to happen again. After changing the LRCLK pad drive strength to the maximum value the issue is gone. Same fix works on a mx6dl Colibri board as well.

2016-06-02ASoC: sgtl5000: Place optional properties in the correct sectionFabio Estevam1-9/+9
'micbias-resistor-k-ohms' and 'micbias-voltage-m-volts' are optional properties, so move them below the 'Optional properties' line. While at it, fix a typo in 'mentioned'. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-10-20ASoC: sgtl5000: Add MicBias voltage supportJean-Michel Hautbois1-1/+6
Some systems may require to specify a bias different than default (1.25V). This adds a property in sgtl5000 codec. The property is specified in milli-volts so that it is coherent with datasheet.

2014-10-20ASoC: sgtl5000: Add MicBias resistor support in DTJean-Michel Hautbois1-0/+8
Some systems may require a different resistor than the default one (4K). This adds a property in sgtl5000 codec. It keeps the default of 4K when nothing is specified so it does not break existing code.

2014-10-15ASoC: sgtl500: Document the required suppliesFabio Estevam1-0/+10
sgtl5000 has two required supplies: VDDA and VDDIO and one optional supply: VDDD, so document this properly. Not passing VDDA and VDDIO prevents the driver to probe successfully. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2013-06-12ASoC: sgtl5000: Add 'clocks' entry as a required properyFabio Estevam1-0/+3
Since commit 9e13f345 (ASoC: sgtl5000: Let the codec acquire its clock) , the 'clocks' entry is mandatory, so update the binding doc. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>
