This seems to be inverted.
Consider you have an active low GPIO reset.
In order to reset it:
Put the GPIO to logic level 0
Wait some time
Put the GPIO to logic level 1
gpiod_set_value(priv->rstb_gpio, 1), means the GPIO in the active
state (0 in this example).
, so this should be:
gpiod_set_value(priv->rstb_gpio, 1);
usleep_range(500, 1000);
gpiod_set_value(priv->rstb_gpio, 0);
