rk3399 Android6.0上调试ov8858，按照wiki资料配置了cam_board.xml，但没有图像输出，问下可能原因有哪些？修改的配置信息：
1、在dts中配置：
&isp0{
gpios-cifpower = <&gpio7 GPIO_B4 GPIO_ACTIVE_HIGH>;
status = "okay";
};
2、 kernel/drivers/media/video/rk_camsys/camsys_drv.c 中
enum of_gpio_flags flags; int cifpower_io; int io_ret; cifpower_io = of_get_named_gpio_flags(dev->of_node, "gpios-cifpower", 0, &flags); camsys_trace(1, "1-gpios-cifpower： gpio=%d", cifpower_io); if(gpio_is_valid(cifpower_io)){ cifpower_io = of_get_named_gpio_flags(dev->of_node, "gpios-cifpower", 0, &flags); camsys_trace(1, "gpios-cifpower： gpio_request"); io_ret = gpio_request(cifpower_io,"cifpower"); camsys_trace(1, "1-gpios-cifpower： gpio_request=%d", io_ret); if(io_ret < 0){ camsys_err("Request %s(%d) failed","cifpower", cifpower_io); } else{ gpio_direction_output(cifpower_io, 1); gpio_set_value(cifpower_io, 1); camsys_trace(1, "gpios-cifpower： %d high", cifpower_io); } }
3、配置cam_board.xml
