Subject: [PULL REQUEST] i2c for 4.9

Linus,

here is the 4.9 pull request from I2C including:

* centralized error messages when registering to the core
* improved lockdep annotations to prevent false positives
* DT support for muxes, gates, and arbitrators
* bus speeds can now be obtained from ACPI
* i2c-octeon got refactored and now supports ThunderX SoCs, too
* i2c-tegra and i2c-designware got a bigger bunch of updates
* a couple of standard driver fixes and improvements

Please pull.

Thanks,

Wolfram

Hi Wolfram,

I see you didn't pick up the follow-up patch ("gpio: pca953x: add a
comment explaining the need for a lockdep subclass"). Linus acked it
in the end and I'd really prefer for it to go into 4.9, as I don't
know if I'll have time to complete the solution for the lockdep issue
in the next development cycle. Without this explanation, the random
lockdep_set_subclass() call looks out of place.

Thanks,
Bartosz

This was planned for the following pull request. Didn't want to change
what was successfully in linux-next for a while.

Would you mind double-checking my merge.

It looked very trivial, but it would be good to have somebody else
give that gpio-pca953x.c conflict a look to verify that I didn't screw
up the 'id' variable split.
