From b2cc2b5111db43b35b5de7252127bbc8d6806e34 Mon Sep 17 00:00:00 2001 From: Erwan Le Ray Date: Wed, 20 May 2020 15:39:31 +0200 Subject: [PATCH] dt-bindings: serial: add generic DT binding for announcing RTS/CTS lines 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.
