How can is define the reset,powerdown,and MCLK pin in jextson TX1 dtsi file?
if I use the f9 is mclk pin ,in the dtsi file ,How can is define the mclk pin?
this is OK?

@sensor_test
Yes, that is correct, you are reference to the right place.

If I define the H8 pin is to the sensor reset,
the below is right?
#define CAM1_RST_L TEGRA_MAIN_GPIO(H, 8)
reset-gpios = <&gpio CAM0_RST_L GPIO_ACTIVE_HIGH>;

Use TEGRA_GPIO(H, 8) instead.

You may also need to hog the gpio, take a look at:
