Subject: [PATCH v4 1/2] i2c: add binding to mark a bus as supporting SMBus-Alert
Date: Wed, 5 May 2021 15:14:38 +0200	[thread overview]
Message-ID: <1620220479-2647-2-git-send-email-alain.volmat@foss.st.com> (raw)
In-Reply-To: <1620220479-2647-1-git-send-email-alain.volmat@foss.st.com>

Since SMBus-Alert is an optional feature of SMBUS which
requires an additional pin, the smbus binding cannot be
used to indicate its support.

Add an additional smbus-alert binding specific for it and
update the description text of smbus to avoid mentioning
SMBus-Alert
