[PATCH 1/2] ASoC: omap: rx51: Add stereo output support to audio jack

[Jarkko Nikula]

Audio jack in Nokia RX-51/N900 is driven by TPA6130 headphone amplifier.
This patch adds support for it and stereo output can be active when
"Jack Function" == "TV-OUT" || "Headphone".

As the TPA6130 can output very high volume levels the output is limited
with snd_soc_limit_volume. Limiting value is found from Maemo kernel sources.

[PATCH 2/2] ASoC: omap: rx51: Add earphone support

[Jarkko Nikula]

Earphone in Nokia RX-51/N900 is connected to left HP output of B part of the
TLV320AIC34 dual codec. In RX-51 the codec A is used as a traditional codec
and the codec B as an auxiliary device.

Audio from codec A goes via the codec B to earphone:
MONO_LOUT of A -> LINE2R of B (B interconnects) -> HPLOUT of B -> Earphone.

Take earphone into use by utilizing the recent ASoC auxiliary and
cross-device support.

This is not the most optimal way to handle but anyway the N900 is a nice
test and development environment for ASoC cross-device etc. stuff so take
the codec B part into use.

This looks like a PIN_SWITCH() DAPM control?
