Hello Mark, Will,

Any other suggestions for this patch set?

Hi6220 is one mobile solution of Hisilicon, this patchset contains
initial support for Hi6220 SoC and HiKey development board, which
supports octal ARM Cortex A53 cores. Initial support is minimal and
includes just the arch configuration, clock driver, device tree

PSCI is enabled in device tree and there is no problem to boot all the
octal cores, and the CPU hotplug is also working now, you can download
and compile the latest firmware based on the following link to run this
patch set:

Changes v4:
* Rebase to kernel 4.1-rc1
* Delete "arm,cortex-a15-gic" from the gic node in dts

Changes v3:
* Verified the CPU hotplug based on the new released firmware
* Redefined the compatible strings of four system controllers in dts
* Setting COMMON_CLK_HI6220 to a bool symbol
* Keep CONFGI_ARCH_HISI sorted alphabetically

Changes v2:
* Split the DT bindings documents into earlier patches
* Change SMP enable method from spin-table to PSCI in device tree
* Remove "clock-frequency" from armv8-timer device node in device tree
* Add more description about Hisilicon designed system controllers
in DT bindings document
* Enable high speed clock on UART1 mux
* Other changes based on the discussion in the mailing list:
