So in imx290_power_on() the reset signal should be cleared/de-asserted with gpiod_set_value_cansleep(imx290->rst_gpio, 0), and in imx290_power_off() the value of 1 must be used to apply/assert the reset to the sensor. In the device tree the reset pin is described as GPIO_ACTIVE_LOW, and gpiod_set_value_xxx() functions take this into account, - when devm_gpiod_get_optional() is called with GPIOD_ASIS, the GPIO is not initialized, and the direction must be set later; using a GPIO without setting its direction first is illegal and will result in undefined behavior. Fix this by using GPIOD_OUT_HIGH instead of GPIOD_ASIS (this asserts the reset signal to the sensor initially).
