[PATCH v9 0/6] arm64,hi6220: Enable Hisilicon Hi6220 SoC

[bintian.wang@huawei.com (Bintian)]

Hi Will, Mark and other ARM64 DT maintainers,

Could you help ack this version? although Will, Kevin and Tyler have
tested this patch set, I think also need an ack from you.

The clock driver has been merged to linux-next, so I just add the clock
header file to this patch set to avoid compilation error.

Thanks,

Bintian
