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