Extperiph1 don't have signal out with xavier nx

Hi everyone
I use Xavier NX on our custom board. I’m sure the board is good. I measure extperiph1 with no signal output.
Is it on by default?What should I do to make it output?
My usage in dt tree as follows:
/* Define any required hw resources needed by driver /
ie. clocks, io pins, power sources */
clocks = <&bpmp_clks TEGRA194_CLK_EXTPERIPH1>,
<&bpmp_clks TEGRA194_CLK_EXTPERIPH1>;
clock-names = “extperiph1”, “pllp_grtba”;
mclk = “extperiph1”;

wish anyone can give me some guide,Thanks!


What is your purpose of using this clk? For camera?

YES ,i find that the clk signal would be output when the camera was open,otherwise,there is no signal out.


Yes, that sounds a normal clk behavior. Anything wrong?
