MIPI CSI Clock questions

Hi：

Recently, I was testing the ov5640 camera on the imx8mm platform, but using an oscilloscope to test the 5640 MIPI clock, only 18M was found. How can I modify the mipi clock? The drive path I used is:drivers/media/platform/mxc/capture/ov5640_mipi_v2.c

what bsp version do you use? did you use nxp board or your customized board? did you use your own bsp or nxp demo images?
