From: Nam Cao <namcao@linutronix.de> stable inclusion from stable-v6.6.9 commit dc958dd32ce850e97377482d4b6489bfbead9613 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8SU2D Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit f6e3b40a2c89c1d832ed9cb031dc9825bbf43b7c upstream. The driver always registers pin configurations in device tree. This can cause some inconvenience to users, as pin configurations in the base device tree cannot be disabled in the device tree overlay, even when the relevant devices are not used. Ignore disabled pin configuration nodes in device tree.
