Merge branch 'i2c/for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
- bus recovery can now be given a pinctrl handle and the I2C core will
do all the steps to switch to/from GPIO which can save quite some
boilerplate code from drivers
- "fallthrough" conversion
- driver updates, mostly ID additions
