    Pull i2c updates from Wolfram Sang:
     "For 3.19, the I2C subsystem has to offer special candy this time.
      Right in time for Christmas :)
    
       - I2C slave framework: finally, a generic mechanism for Linux being
         an I2C slave (if the bus driver supports that).  Docs are still
         missing but will come later this cycle, the code is good enough to
         go.
       - I2C muxes represent their topology in sysfs much more detailed.
         This will help users to navigate around much easier.
       - irq population of i2c clients is now done at probe time, not device
         creation time, to have better support for deferred probing.
       - new drivers for Imagination SCB, Amlogic Meson
       - DMA support added for Freescale IMX, Renesas SHMobile
       - slightly bigger driver updates to OMAP, i801, AT91, and rk3x
         (mostly quirk handling, timing updates, and using better kernel
         interfaces)
       - eeprom driver can now write with byte-access (very slow, but OK to
         have)
       - and the bunch of smaller fixes, cleanups, ID updates..."
