i2c: add binding to mark a bus as supporting SMBus-Alert
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 Signed-off-by: Alain Volmat <alain.volmat@foss.st.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Wolfram Sang <wsa@kernel.org>
