Hello,

My keyboard and mouse don't work anymore with my Cyrus+ board with a FSL 
P50x0 PowerPC SoC [1] after the devicetree updates for 5.19 [2].
After reverting the devicetree updates, my keyboard and mouse work 
without any problems.
I figured out that the issue is in the patch for the file platform.c 
[3].  I created a patch for reverting the problematic code. (see 
attachment)
After reverting the changes with the attached patch, the keyboard and 
mouse work again.
Please check your changes in the file platform.c [3].

Thanks,
Christian

Based on your patch I would say the culprit commit is

     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
