BTW, H6 BSP uses FIFO size 40:
https://github.com/orangepi-xunlong/OrangePiH6_Linux4_9/blob/master/drivers/media/rc/sunxi-ir-dev.c#L290
Have you tried filling the fifo with over 40 words on H6, to see if it works?
I know it's docummented as having 64 words in the manual, so maybe Allwiner
just didn't care enough to make the driver configurable, and the H6
FIFO really has that depth.
