Subject: [PATCH v2] ARM: dts: rockchip: temporarily remove emmc hs200 speed from rk3288-veyron-speedy.
Date: Tue, 27 Sep 2016 13:53:46 -0700 [thread overview]
Message-ID: <87twd1vzc5.fsf@aikidev.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 903 bytes --]
This essentially mimics what was done with rk3288-veyron-minnie in
commit 984926781122f034d5bc9962815d135b6c4a8e1d.
The eMMC of the speedy Chromebook also appears to need the same tuning
workaround, as it frequently fails to recognize the eMMC without it.
