Merge branch 'i2c/for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
- mainly feature additions to drivers (stm32f7, qup, xlp9xx, mlxcpld, ...)
- conversion to use the i2c_8bit_addr_from_msg macro consistently
- move includes to platform_data
- core updates to allow the (still in review) I3C subsystem to connect
- and the regular share of smaller driver updates
