Subject: [PATCH] dt-bindings: fsi-master-gpio: Document "no-gpio-delays" property
Date: Tue, 29 May 2018 11:43:40 +1000 [thread overview]
Message-ID: <1a2aaf52c2f4d948d55ccf3953db92528c296733.camel@kernel.crashing.org> (raw)
In-Reply-To: <20180529013044.23815-6-benh@kernel.crashing.org>
Support for this is being added to the driver but the original
patch forgot to add this documentation.
