Merge branch 'i2c/for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:

 - new driver for ICY, an Amiga Zorro card :)

 - axxia driver gained slave mode support, NXP driver gained ACPI

 - the slave EEPROM backend gained 16 bit address support

 - and lots of regular driver updates and reworks
