Merge branch 'i2c/for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "New stuff from the I2C world:

   - in the core, getting irqs from ACPI is now similar to OF

   - new driver for MediaTek MT7621/7628/7688 SoCs

   - bcm2835, i801, and tegra drivers got some more attention

   - GPIO API cleanups

   - cleanups in the core headers

   - lots of usual driver updates"
