[PATCH V2] goldfish: add goldfish match node for dt driver probe
From: yalin wang
Date: Fri Nov 06 2015 - 02:12:57 EST
qemu use device tree to bootup linux kernel,
we need add device node match table to plaftorm driver,
so that can probe the goldfish driver correctly.
test by this qemu:
git clone https://android.googlesource.com/platform/external/qemu
