Subject: [PATCH v5 4/8] dt-bindings: mmc: Add optional generic properties for mmc
Date: Fri,  1 Nov 2019 11:35:49 +0530	[thread overview]
Message-ID: <1572588353-110682-5-git-send-email-manish.narani@xilinx.com> (raw)
In-Reply-To: <1572588353-110682-1-git-send-email-manish.narani@xilinx.com>

Add optional properties for mmc hosts which are used to set clk delays
for different speed modes in the controller.
