Subject: [PATCH 2/2] serial: stm32: Use generic DT binding for announcing RTS/CTS lines
Date: Wed, 20 May 2020 15:39:32 +0200 [thread overview]
Message-ID: <20200520133932.30441-3-erwan.leray@st.com> (raw)
In-Reply-To: <20200520133932.30441-1-erwan.leray@st.com>
Add support of generic DT binding for annoucing RTS/CTS lines. The initial
binding 'st,hw-flow-control' is not needed anymore since generic binding
is available, but is kept for backward compatibility.
