hi,在imx6ulevk里，用74LV595PW去控制复位功能。

驱动在drivers/gpio/gpio-74x164.c

有个问题是比如CSI_RST,CSI_PWDN,LCD_nPWREN 的控制实现相应的驱动在文件里？

I think CSI_RST is the reset for the camera.

you can setup the GPIO pin for CSI_RST in your board's dtsi file.

you can use it in the drivers by of_get_named_gpio().

for example : ov5640.c, you can find the of_get_named_gpio() to get the pwn_gpio in ov5640_probe().

但LCD_nPWREN 这一pin实际没有找到，就是说LCD屏的电源控件使能是什么实现
