Virtual Media device
-------------------------------
Virtual Media device is used to manage all modules in image capture subsystem
of imx8qxp/qm platform. ISI(Image Sensor Interface), MIPI CSI, Parallel CSI
device node should be under it.
Required properties:
- compatible : must be "fsl,mxc-md";
- reg : Must contain an entry for each entry in reg-names;
- #address-cells: should be <1>;
- #size-cells : should be <1>;
- ranges : use to handle address space
Optional properties:
- parallel_csi: indicate that camera sensor use parallel interface
For example:
cameradev: camera {
compatible = "fsl,mxc-md", "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges;
isi@58100000 {
compatible = "fsl,imx8-isi";
reg = <0x58100000 0x10000>;
...
};
csi@58227000 {
compatible = "fsl,mxc-mipi-csi2";
...
};
...
};
