6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nam Cao namcao@linutronix.de
commit 5c584f175d32f9cc66c909f851cd905da58b39ea 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.
