[PATCH v1 0/2] Support headset on Tegra boards that use WM8903

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Some devices have a 4-pin jack instead of a 3-pin and currently the
WM8903 configuration is hardcoded to the case of 3-pin jack in the
Tegra's ASoC driver. A new device-tree property is required in order
to convey that hardware has a 4-pin jack, and thus, microphone's
detection needs to be done in a different way.

In particular this is needed for Acer A500 tablet device that has
a 4-pin headset jack, otherwise userspace sees headset instead of
headphones and internal microphone isn't enabled by ALSA UCM rule
when it should be. Please review and apply, thanks in advance.
