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

 i2c-ocores uses the platform bus, so you need to provide a struct
 platform_device with the base address and interrupt number. The
 dev.platform_data of the device should also point to a struct
-ocores_i2c_platform_data (see linux/i2c-ocores.h) describing the
+ocores_i2c_platform_data (see linux/platform_data/i2c-ocores.h) describing the
 distance between registers and the input clock speed.
 There is also a possibility to attach a list of i2c_board_info which
 the i2c-ocores driver will add to the bus upon creation.
