[PULL REQUEST] i2c for 4.2

From: Wolfram Sang
Date: Thu Jun 25 2015 - 14:51:43 EST

Linus,

here is the I2C pull request. Highlights:

* new drivers for Mediatek I2C, APM X-Gene, Broadcom Settop
* major updates to at91, davinci
* bugfixes to the mux infrastructure when dealing with the new quirk
mechanism
* more users for the bus recovery feature
* further improvements to the slave framework

Plus, the usual bunch of smaller driver and core improvements and fixes.

There is one patch removing old code from an ARM platform. This has been
acked by the sh_mobile maintainer Simon Horman.

Please pull.

Thanks,

Wolfram
