[V2 2/2] arm64: dts: Add dts files for Hisilicon Hi3660 SoC

[Chen Feng]

Add initial dtsi file to support Hisilicon Hi3660 SoC with
support of Octal core CPUs in two clusters(4 * A53 & 4 * A73).

Also add dts file to support HiKey960 development board which
based on Hi3660 SoC.
The output console is earlycon "earlycon=pl011,0xfdf05000".
And the con_init uart5 with a fixed clock, which already
configured at bootloader.

When clock is available, the uart5 will be modified.

Tested on HiKey960 Board.

The unit-address here is incorrect. The base address of this memory is
not zero.

This clock-frequency property should not be required; please remove it.

Your FW should program CNTFRQ_EL0 with the timer frequency.

Thanks,
Mark.

Thanks!

Hi Chen Feng,

Can you send out the v3 to address above comments?
And I will pick up it soon.

You can add more specific compatibles as you mentioned this SoC contains
Cortex A53 & A73.

Applied both to the hisilicon SoC tree
with minimal changes about the format.
