GPIO lines in da9063 are assigned dynamically, while majority of SOC GPIO drivers assign their GPIOs in static manner (GPIO line numbers can be calculated). This introduces regression if deep probe support is used. If da9063 GPIOs are registered before the SOCs GPIOs, there is a good chance that the SOCs statically computed GPIO line numbers will already be used by PMIC. Ensure all SOCs GPIO drivers and GPIO lines get registered before the da9063 registers its own gpiochip.
