Subject: [PATCH v2 2/5] dt-bindings: xilinx_dma: add optional xlnx, sg-length-width property
Date: Thu, 21 Jun 2018 13:58:19 +0200 [thread overview]
Message-ID: <20180621115822.20058-2-andrea.merello@gmail.com> (raw)
In-Reply-To: <20180621115822.20058-1-andrea.merello@gmail.com>
The width of the "length register" cannot be autodetected, and it is now
specified with a DT property. Add DOC for it.
