Subject: [PATCH v6 4/8] dt-bindings: mmc: Add optional generic properties for mmc
Date: Wed, 20 Nov 2019 12:17:25 +0530	[thread overview]
Message-ID: <1574232449-13570-5-git-send-email-manish.narani@xilinx.com> (raw)
In-Reply-To: <1574232449-13570-1-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.
