The bulk of this seems to be new hardware support code.

Please send it during the 5.1 merge window, not as fixes at post-rc6 time.

Ok, I'll remove:
      irqchip/csky: Support csky,dh7k SOC intc driver
      dt-bindings: csky,apb-intc: Add dh7k SOC support

Aside from this, I also noticed that the new code is for drivers/irqchip,
which is a separate subsystems with its own maintainers, who were
neither on Cc nor did they Ack the patches.

Generally, those should get merged through the respective subsystem
trees as listed in the linux/MAINTAINERS file.

Yes, there are:
	dt-bindings: csky,apb-intc: Add vector irq mode
	irqchip/csky: Add support-vector-irq for apb-intc
	irqchip/csky: Optimize remove unnecessary loop irq handle
	irqchip/irq-csky-mpintc: Add triger type and priority
	dt-bindings: interrupt-controller: Update csky mpintc

I just send these patches to the mail-list before, but not get Ack. I'll add
Cc in these patches and resend them to the mail list.

Ok, I'll remove them in this pull request.
