Linus,
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...
Plese pull!
Thanks,
Wolfram
