Thanks.

I have tested your series of patch and it seems to have also an issue with my
use case.
I am working with w1-gpio.
I got this issue: 
=> w1 bus
check_dir_flags: flags 0x16 has GPIOD_IS_OUT and GPIOD_IS_IN
gpio_sunxi PD: PD error: set_dir_flags for gpio PD2 has invalid dir flags 0x16
Bus 0:  onewire  (active)
        w1_eeprom at 0 (0) uclass w1_eeprom : family 0x0
