ASoC: machine support for Toshiba e740 PDA
This patch provides suupport for the wm9705 AC97 codec on the Toshiba e740. Note: The e740 has a hard headphone switch that turns the speaker off and is not software detectable or controlable. Also both headphone and speaker amps share a common output enable. Signed-off-by: Ian Molton <ian@mnementh.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
