This adds a driver for the TI PCM9211 digital audio interface transceiver. The driver currently only handles the receiver aspect of the chip. Some extra device-tree fields are introduced to allow configuration of pin functions directly out of this driver.

Signed-off-by: Julian Scheel julian@jusst.de

--- Changes in v2: - Fix checkpatch errors (long lines, * association) - Fix typos in device-tree documentation - Fix group-function dt. Mask was applied on unshifted data - Fix error check for int0 gpio lookup - Fix ADC rate list (92->96kHz) - Add support for AUXOUT as second DAI
