Based on your patch I would say the culprit commit is 
https://github.com/torvalds/linux/commit/a1a2b7125e1079cfcc13a116aa3af3df2f9e002b

     of/platform: Drop static setup of IRQ resource from DT core

     Now that all the DT drivers have switched to platform_get_irq() we 
can now
     safely drop the static setup of IRQ resource from DT core code.

     With the above change hierarchical setup of irq domains is no longer
     bypassed and thus allowing hierarchical interrupt domains to describe
     interrupts using "interrupts" DT property.

Can you please provide you device tree ?

Do you use any out-of-tree drivers ?

Thanks
