[PATCH v3 0/2] i2c: stm32: add host-notify support via i2c slave

From: Alain Volmat
Date: Mon Aug 03 2020 - 01:45:22 EST

This serie replaces the previous 'stm32-f7: Addition of SMBus Alert /
Host-notify features' serie to only focus on the SMBus Host-Notify feature.
It should be applied with "[PATCH] i2c: add binding to mark a bus as SMBus"
from Wolfram which defines the newly introduced "smbus" binding.

Alain Volmat (2):
i2c: smbus: add core function handling SMBus host-notify
i2c: stm32f7: Add SMBus Host-Notify protocol support
