stable inclusion from stable-v5.10.132 commit d8d42c92fe564ed9dad36a5b0dcfc3b12bfb7965 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5YS3T
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit e95ea0f687e679fcb0a3a67d0755b81ee7d60db0 ]
Device-tree incorrectly used "ngpio" which caused the driver to fallback to 32 ngpios.
This platform has 62 GPIO registers.
