From: Erwan Le Ray Date: Wed, 20 May 2020 13:39:31 +0000 (+0200) Subject: dt-bindings: serial: add generic DT binding for announcing RTS/CTS lines X-Git-Tag: microblaze-v5.10~119^2~37 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=b2cc2b5111db43b35b5de7252127bbc8d6806e34;p=linux-2.6-microblaze.git 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.
