Subject: [PATCH v2 05/11] dt-bindings: mmc: arasan: Update Documentation for the input clock
Date: Mon,  1 Jul 2019 10:59:45 +0530	[thread overview]
Message-ID: <1561958991-21935-6-git-send-email-manish.narani@xilinx.com> (raw)
In-Reply-To: <1561958991-21935-1-git-send-email-manish.narani@xilinx.com>

Add documentation for an optional input clock which is essentially used
in sampling the input data coming from the card.
