Subject[PULL REQUEST] i2c for 4.13
Linus,

here is my first pull request this merge window for the I2C subsystem. A
little later than usual but we needed to sort out one real build problem
and then a few false positives from buildbot. But now everything seems
in order. This pull request contains:

* i2c core reorganization. One source file became too monolithic. It is
now split up, yet we still have the same named object as the final
output. This should ease maintenance.
* new drivers: ZTE ZX2967 family, ASPEED 24XX/25XX,
* designware driver gained slave mode support
* xgene-slimpro driver gained ACPI support
* bigger overhaul for pca-platform driver
* the algo-bit module now supports messages with enforced STOP
* slightly bigger than usual set of driver updates and improvements

Please pull.

Thanks,

Wolfram
