Linus,

I2C has for 5.18: tracepoints when Linux acts as an I2C client, added
support for AMD PSP, whole subsytsem now uses generic_handle_irq_safe(),
piix4 driver gained MMIO access enabling so far missed controllers with
AMD chipsets, plus a bulk of device driver updates, refactorization, and
fixes.

Please pull.

Thanks,

   Wolfram
