Merge tag 'at91-fixes-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/at91/linux into arm/fixes
AT91 fixes for 6.4
It contains:
- fix imbalanced reference counter for ethernet devices; without it
system hangs after consecutive suspend/resume cycles;
- fix debounce delay property for shutdown controller; the initial DT
property is not what the driver expects.
