ARM: dts: rockchip: add Pinky board

A patch from ťARM: dts: rockchip: add initial support for rk3288 Chrome-devicesŤ in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Tue, 7 Jul 2015 20:09:34 +0200

Commit-Message

While pinky was one of the earlier development models, is on the list of endangered species today and nearly extinct, I want to keep mine around for the foreseeable future after spending all the time making a nice hole into the base below the dut-connector. Signed-off-by: Heiko Stuebner <heiko@...>
