Merge branch 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c fixes from Wolfram Sang:
"A new ID for the i801 driver and some Documentation fixes to make it
easier for people to find the bindings (which is also a basis for
further improvements in that area)"

* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
i2c: wmt: make bindings file name match the driver
i2c: sun6i-p2wi: make bindings file name match the driver
i2c: stu300: make bindings file name match the driver
i2c: mt65xx: make bindings file name match the driver
i2c: iop3xx: make bindings file name match the driver
i2c: i801: Add support for Intel Comet Lake
