Date: Wed, 31 Aug 2016 21:10:58 +0800 From: Guodong Xu <guodong.xu@...aro.org> To: xuwei5@...ilicon.com, robh+dt@...nel.org, mark.rutland@....com, catalin.marinas@....com, will.deacon@....com Cc: devicetree@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Guodong Xu <guodong.xu@...aro.org>, Ulf Hansson <ulf.hansson@...aro.org>, Jaehoon Chung <jh80.chung@...sung.com>, Jinguojun <kid.jin@...ilicon.com> Subject: [PATCH] arm64: dts: hi6220: add sd-uhs- properties into dwmmc_1 With these properties added, sd cards inserted into hikey can work at UHS mode if they have such capability. Note, this depends on HiKey UHS-SD support patch [1] to work properly. If you didn't add this patch, but added sd-uhs- properties into dwmmc_1, then sd cards cannot work. As of this post, patch [1] has been integrated into maintainer's next branch [2].
