Linus, here is the pull request from I2C for the 4.4 merge window: * new drivers: UniPhier (with and without FIFO) * some drivers got some bigger rework: ismt, designware, img-scb (rcar had to be reverted because issues were showing up just lately) * ACPI: reworked the device scanning and added support for muxes And quite a lot of driver bugfixes and cleanups this time. All files touched outside of the i2c realm have proper acks. Note there will be a merge conflict in the designware driver due to a bugfix applied late to 4.3. Not that you'd really need it, but my proposed resolution is here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/conflict-4.4 Resolving the conflict, I noticed asymmetry in the runtime_pm error handling of the designware driver. I'll ask the developers about this. However, I hope you'll pull this, so we can go from there and fix it incrementally.
