The SSP ports PXA series processors can be used to implement a variety of audio interface formats. This patch implements support for I2S, DSP A and DSP B modes on these ports. This patch is based on the previous out of tree pxa2xx-ssp driver (which was originally written by Liam Girdwood with updates from Philipp Zabel and Nicola Perrino) and pxa3xx-ssp driver (originally written by Seth Forsee based on the pxa2xx-ssp driver). Testing coverage is not complete currently. Tested-by: Daniel Ribeiro <drwyrm@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
