Allwinner H6 IR is similar to A31 and can use same driver.

Add support for it.

Please make a comment here, that this is known broken on some boards and may
result IRQ flood if enabled. Otherwise noone will know.

I'm planning to send a v4 next week with the IRQ_NONE return as Maxime
suggested it.
https://github.com/clementperon/linux/tree/h6_ir_v4

But maybe we could also use the bit 5 of the IRQ status.

Thanks, that's nice, but that will not make the HW work. That will just disable
it. The comment is still necessary.

I have pushed a new version on my github.
https://github.com/clementperon/linux/commits/h6_ir_v4

I will submit it, if you are ok with it.

Thanks,
Clément
