Subject: [PATCH v4 4/8] dt-bindings: mmc: arasan: Add optional properties for Arasan SDHCI
Date: Tue, 29 Oct 2019 16:00:38 +0530	[thread overview]
Message-ID: <1572345042-101207-4-git-send-email-manish.narani@xilinx.com> (raw)
In-Reply-To: <1572345042-101207-1-git-send-email-manish.narani@xilinx.com>

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