Now that the JZ4740 and similar SoCs have a pinctrl driver, we rely on
the pins being properly configured before the driver probes.

Shouldn't this be replaced with a call to:
pinctrl_pm_select_sleep_state();

Shouldn't this be replaced with a call to:
pinctrl_pm_select_default_state();

Kind regards

You're totally right. I'll change it.

Thanks,
