[PATCH 2/4] ARM: dts: rockchip: add shared rk3288-veyron files

Heiko Stuebner heiko at sntech.de
Fri Jul 10 17:29:20 PDT 2015


From: Alexandru M Stan <amstan at chromium.org>

This adds the shared devicetree files for the Veyron device family.
They are split, as not all veyron devices are chromebooks and
not all contain a sd-card slot.
