From 05ffc630627003c7bf275eec05b0eae81e0016b1 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Tue, 7 Jul 2015 20:09:34 +0200 Subject: [PATCH] ARM: dts: rockchip: add veyron-pinky board 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.
