PS2, Line 282: For AMD systems this wasn't implemented until
             :   linux v5.15.

PS2, Line 288: As of linux v6.0, the ACPI subsystem doesn't take the GPIO `wake` bit into
             :   account when deciding on which power state to put the device in before
             :   suspending the system.
It’d be great if you referenced the commit.
