Subject: [PATCH 1/2] pinctrl: pinconf-generic: sort pin configuration params alphabetically
Currently, the dt_params array in drivers/pinctrl/pinconf-generic.c
is not sorted in the same order as the enum pin_config_param in
include/linux/pinctrl/pinconf-generic.h.
Sort enum pin_config_param, conf_items, dt_params, alphabetically
for consistency.
