At present pinctrl driver gets probed in ich6_gpio driver's probe
routine, which has two issues:
- Pin's PADs only gets configured when GPIO driver is probed, which
is not done by default. This leaves the board in a partially
functional state as we must initialize PADs correctly to get
perepherals fully working.
- The probe routine of pinctrl driver is called multiple times, as
normally there are multiple GPIO controllers. It should really
be called just once.
Move the call to syscon_get_by_driver_data() from ich6_gpio driver
to cpu_init_r().
