Merge branch 'i2c/for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
- the I2C core gained helpers to assist drivers in handling their
suspended state, and drivers were converted to use it
- two new fault-injectors for stress-testing
- bigger refactoring and feature improvements for the ocores,
sh_mobile, and tegra drivers
- platform_data removal for the at24 EEPROM driver
- ... and various improvements and bugfixes all over the subsystem
