I had a test on Hisilicon D03 which needs patch 1 and 2 in this patch set to enable the mbigen irqchip, and it works pretty good.
Patch 1/3 can remove the device dependency for the irqchip and platform devices, and I removed my patch (ACPI: irq: introduce interrupt producer) then add your patch 2/3, devices such as SAS and native network works fine on my D03.
I will comment on the patches later.
Thanks Hanjun
