From 1b340bd7e444f20eb2df88c65fa34960c4736ee9 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 30 Jul 2008 19:12:04 +0100 Subject: ASoC: Add PXA SSP support 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.
