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 #1.1: 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.
