Merge branch 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux
Pull embedded i2c update from Wolfram Sang: "This only contains one new driver which had multiple dependencies (pinctrl, i2c-mux-rework, new devm_* functions), so I decided to wait for rc1. Plus, it had to wait a little for the ack of a devicetree maintainer since the bindings were not trivial enough for me to pass through. So, given that, I hope there is still something like the "new driver rule", so we could have the driver in 3.5 and people can start using it. That would make merging support for some boards easier for 3.6 since the dependency on this driver is gone then." * 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux: i2c: Add generic I2C multiplexer using pinctrl API
