From: Mark Brown Date: Fri, 19 Aug 2011 13:40:07 +0000 (+0900) Subject: ARM: S3C64XX: Use module identification for Cragganmore system builds X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d0f0b43f78b88b42e795e4c28f3591cb57590692;p=linux-beck.git ARM: S3C64XX: Use module identification for Cragganmore system builds The Cragganmore system is modular with I2C based identification chips on the system allowing identification of the system build. Provide a stub I2C driver which parses the module IDs and uses them to select the appropriate audio subsystem components to register. To avoid confusion due to having the mini-driver in the system the driver is placed in a separate file.
