Subject: [PULL REQUEST] i2c for 4.7
Linus,
I2C updates for 4.7:
* Peter Rosin did some major rework on the locking of i2c muxes by
seperating parent-locked muxes and mux-locked muxes. This avoids
deadlocks/workarounds when the mux itself needs i2c commands for
muxing. And as a side-effect, other workarounds in the media layer
could be eliminated. Also, Peter stepped up as the i2c mux
maintainer and will keep an eye on these changes.
* major updates to the octeon driver
* Add a helper to the core to generate the address+rw_bit octal and
make drivers use it
* quite a bunch of driver updates
Please pull.
Thanks,
Wolfram
