[PATCH 06/17] ASoC: twl6040: Use chip defaults in the initial reg_cache

From: Peter Ujfalusi
Date: Thu Sep 15 2011 - 08:43:39 EST


Reset the twl6040_reg array to hold the chip default values.
The only changed values were for the microphone input selection.
Select no input for the microphones in the twl6040_init_chip function.
