You should use devm_gpiod_get() and friends. If you do not have corresponding Linux device node, then it is fwnode_get_named_gpiod().
It seems the fwnode_get_named_gpiod() function will be used in my case, but how can I get the fwnode??
There is acpi_fwnode_handle() in include/acpi/acpi_bus.h. However, if you have Linux device available you should really use devm_gpio_* functions instead.
