From 9e991a4bf3290b0787d33fa72144f6eec656f20d Mon Sep 17 00:00:00 2001 From: Jassi Brar Date: Tue, 27 Apr 2010 15:56:56 +0900 Subject: [PATCH] ASoC: S3C: I2Sv2: New field for controller feature In order to make s3c-i2s-v2.c manage controllers with minor quirks and variation in features, we define a per-block flag that indicates the availability/lack of a particular feature to the s3c-i2s-v2.c While adding support for new SoCs' I2S, check for the blocks of older SoCs that have similar feature and set the flag for that feature.
