Subject: [PATCH 4/7] dt-bindings: fsi: fsi2spi: Document new restricted property
Date: Thu, 20 Aug 2020 12:02:25 -0500 [thread overview]
Message-ID: <20200820170228.42053-5-eajames@linux.ibm.com> (raw)
In-Reply-To: <20200820170228.42053-1-eajames@linux.ibm.com>
Add documentation for the "fsi2spi,restricted" property which indicates
a controller shouldn't sequence loops and therefore has a smaller
transfer size.
