Subject: [PATCH 10/10] ARM: shmobile: r8a7790: lager: Enable UHS-I SDR-50
Date: Sat, 12 Mar 2016 10:15:12 +0100	[thread overview]
Message-ID: <1457774112-16958-11-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1457774112-16958-1-git-send-email-wsa@the-dreams.de>

From: Ben Hutchings <ben.hutchings@codethink.co.uk>

Add the "1v8" pinctrl state and sd-uhs-sdr50 property to SDHI{0,2}.

Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk>
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

Changes since RFC:

* rename DT binding name and pinctrl variables to "*uhs" instead of "*1v8"
