in I.MX8MQuad , as a Mipi CSI2 driver , we use fsl,mxc-mipi-csi2_yav ( mxc-mipi-csi2_yav.c )
This Mipi-CSI2 driver is used for OV5640 camera.
but, in I.MX8M mini , to connect Sony IMX219 Camera sensor , they used fsl,imx8mm-mipi-csi driver ( drivers/media/platform/mxc/capture/mxc_mipi_csi.c )
How can use fsl,imx8mm-mipi-csi as a I.MX8MQuad Mipi CSI2 driver?
