[PATCH V2] goldfish: add goldfish match node for dt driver probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
