This adds the bindings, for the MIPI CD-PHY module v0.5 embedded in
some Mediatek soc, such as the mt8365

+description:
+  The SENINF CD-PHY is a set of CD-PHY connected to the SENINF CSI-2
+  receivers. The number of PHYs depends on the SoC model.
+  Depending on the SoC model, each PHYs can be either CD-PHY or D-PHY only
+  capable.
+
+properties:
+  compatible:
+    enum:
+      - mediatek,mt8365-csi-rx
+
+  reg:
+    maxItems: 1
+
+  '#phy-cells':
+    const: 0
+
+  mediatek,phy-type:

Instead of declaring a phy-type here like this, can't we instead declare that in
the phy cells, like we're doing with MTK TPHY and like other non-MediaTek PHYs are
already doing?

device {
	...
	phys = <&csi0_rx PHY_TYPE_CDPHY>;
	...
}

Angelo
