Needn't word "this patch"
Can you list feature here?

Need max retry time, otherwise may dead loop here.

suggest use scope_guard(spin_lock_irq)(&crtc->dev->event_lock)
check other place.

can you use loop for above 3 irqs.

You just set QOS value by blkctrl_regmap. Is it possible to set it blk-ctrl
drivers? Or do it when power on the power domain to avoid use customer's
syscon to other nodes.

When DMA_BIT_MASK(32) > 32, never return failure. Needn't check this
return value.

use devm_add_action_or_reset to avoid goto here.
