Have sent the updated patch
https://lore.kernel.org/linux-pci/1610434192-27995-1-git-send-email-zhangfei.gao@linaro.org/T/#u
We do not need change iort now but just use a quirk for HiSilicon
KunPeng920 and KunPeng930,
since Jean made a change not using fwspec, which make us easier.
* Use device properties for dma-can-stall, instead of a special fwspec
member.
