Pull i2c updates from Wolfram Sang:
"Mostly DT bindings additions this time because Andi was super busy and
I also could only partly cover it.
- new ids for qcom-cci, mt65xx, exynos5, apple, tegra20, k1, i801
- drop support for already removed S3C2410
- introduce and use fwnode_for_each_child_node_scoped()
- mmt65xx: improve write-then-read transactions
- k1: various fixes around bus errors and resets
- usual share of cleanups, minor improvements, PM fixes...
at24 updates:
- add the compatible for Giantec GT24C256C to the device-tree
bindings"
