Merge tag 'i2c-for-7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 - core: cleaner fwnode usage
 - tegra: timing improvements and Tegra264 support
 - lpi2c: fix SMBus block read NACK after byte count
 - amd-mp2, designware, mlxbf, rtl9300, spacemit, tegra: cleanups
 - designware:
    - use a dedicated algorithm for AMD Navi
    - replace magic numbers with named constants
    - replace min_t() with min() to avoid u8 truncation
    - refactor core to enable mode switching
 - imx-lpi2c: add runtime PM support for IRQ and clock handling
 - lan9691-i2c: add new driver
 - rtl9300: use OF helpers directly and avoid fwnode handling
 - spacemit: add bus reset support
 - units: add HZ_PER_GHZ and use it in several i2c drivers
 - at24 i2c eeprom:
    - add a set of new compatibles to DT bindings
    - use dev_err_probe() consistently in the driver
