So probably we can use legacy domain when MIPS IRQ BASE is in the

No, see below.
Here in Loongson systems IRQ 0-15 is occupied by I8259 so I did this
hack.
Well, if you have to consider which Linux IRQ gets assigned,
then your platform is definitely not ready for non-legacy
irqdomains. Just stick to legacy for now until you have removed
all the code that knows the hwirq mapping.
Thanks.
So I have to allocate irq_desc here in driver manually?
No, you are probably better off just dropping this patch, as MIPS
doesn't seem to be ready for a wholesale switch to virtual interrupts.
