Charles Keepax	97aff2c03a	ASoC: wm8904: Correct number of EQ registers ... There are 24 EQ registers not 25, I suspect this bug came about because the registers start at EQ1 not zero. The bug is relatively harmless as the extra register written is an unused one.

Mark Brown	fbc2dae854	ASoC: Support GPIO based microphone detection for WM8904 ... The WM8904 allows microphone detection signals to be brought out as alternate functions of the GPIO signals which can be detected using interrupt inputs on the CPU. Allow this to be configured using platform data. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>	2010-03-16 16:03:30 +00:00

Mark Brown	a91eb199e4	ASoC: Initial WM8904 CODEC driver ... The WM8904 is a high performance ultra-low power stereo CODEC optimised for portable audio applications, with features including a class W amplifier, FLL with free running mode, Mobile ReTune and ground referenced headphone and line outputs. Support for some features, most particularly the digital microphone interface, is not yet present.
