We can perform microphone detection with MICVDD in bypass mode so try to enable that during startup for minimal power - other users or machine constraints will prevent bypass mode being activated if it is unsuitable.
Signed-off-by: Mark Brown <[email protected]> --- This depends on the newly added regulator bypass support which will be going in during the merge window so probably the easiest thing here is if I apply this to the regulator tree? I will be publishing a signed tag if you want to pull it in but for a simple, non-invasive change like this it seems like more trouble than it's worth. drivers/extcon/extcon-arizona.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/drivers/extcon/extcon-arizona.c b/drivers/extcon/extcon-arizona.c index dc81d5f..cdab9e5 100644 --- a/drivers/extcon/extcon-arizona.c +++ b/drivers/extcon/extcon-arizona.c @@ -483,6 +483,11 @@ static int __devinit arizona_extcon_probe(struct platform_device *pdev) regmap_update_bits(arizona->regmap, ARIZONA_JACK_DETECT_ANALOGUE, ARIZONA_JD1_ENA, ARIZONA_JD1_ENA); + ret = regulator_allow_bypass(info->micvdd, true); + if (ret != 0) + dev_warn(arizona->dev, "Failed to set MICVDD to bypass: %d\n", + ret); + pm_runtime_put(&pdev->dev); ret = input_register_device(info->input); -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
