[alsa-devel] [PATCH 2/3] soc - S3C2410 i2s - Add support for master and left justified modes

[Mark Brown]

From: ing. Davide Rizzo <davide at elpa.it>

S3C2410 i2s driver currently manages only i2s protocol (and not left
justified one) and slave mode.
With this small patch, other modes are possible.

This patch to correctly manage codecs in slave mode and left-justified format
