Interrupt storm on some gaming laptops

Interrupt storm on some gaming laptops

[Limonciello, Mario]

Hi,

An interrupt storm was reported on some gaming laptops [1].
This is fixed by a series of commits that has gone into 6.5-rc2.
This interrupt storm causes a pretty dramatic issue of unable to use the 
internal keyboard, so IMO a good idea to take the solution back to 
stable kernels as well.

Here is the series needed for 6.4.y:
968ab9261627 pinctrl: amd: Detect internal GPIO0 debounce handling
a855724dc08b pinctrl: amd: Fix mistake in handling clearing pins at startup
0cf9e48ff22e pinctrl: amd: Detect and mask spurious interrupts
65f6c7c91cb2 pinctrl: amd: Revert "pinctrl: amd: disable and mask 
interrupts on probe"
0d5ace1a07f7 pinctrl: amd: Only use special debounce behavior for GPIO 0
635a750d958e pinctrl: amd: Use amd_pinconf_set() for all config options
3f62312d04d4 pinctrl: amd: Drop pull up select configuration
283c5ce7da0a pinctrl: amd: Unify debounce handling into amd_pinconf_set()

Here is the series needed for 6.1.y:
df72b4a692b6 pinctrl: amd: Add Z-state wake control bits
75358cf3319d pinctrl: amd: Adjust debugfs output
010f493d90ee pinctrl: amd: Add fields for interrupt status and wake status
968ab9261627 pinctrl: amd: Detect internal GPIO0 debounce handling
a855724dc08b pinctrl: amd: Fix mistake in handling clearing pins at startup
0cf9e48ff22e pinctrl: amd: Detect and mask spurious interrupts
65f6c7c91cb2 pinctrl: amd: Revert "pinctrl: amd: disable and mask 
interrupts on probe"
0d5ace1a07f7 pinctrl: amd: Only use special debounce behavior for GPIO 0
