Subject: [PATCH] arm64: dts: uniphier: add cdns,phy-dll-delay-sdclk(-hsmmc) for eMMC
Date: Tue,  4 Apr 2017 11:04:37 +0900	[thread overview]
Message-ID: <1491271477-19806-1-git-send-email-yamada.masahiro@socionext.com> (raw)

Adjust the PHY parameters for more stable access to the eMMC device.
Set the SDCLK output delay value to 21 (including HS200/400 modes).
