Next: [PATCH 3/4] add generic smsc911x support for LogicPD's OMAP3 TORPEDO and SOM dev kits
From: Jean Delvare on 11 Aug 2010 12:50 Hi Linus, Please pull a first round of i2c subsystem updates for Linux 2.6.36 from: git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging.git i2c-for-linus The big thing here is the multiplexing support, with core support as well as support for the popular NXP PCA954x family of multiplexers and switches. It may have a few rough edges left, but overall should work. The rest are small cleanups.
