+title: NXP i.MX7 and i.MX8 MIPI CSI-2 receiver
+
+maintainers:
+ - Rui Miguel Silva <rmfrfs@gmail.com>
+ - Laurent Pinchart <laurent.pinchart@ideasonboard.com>
+
+description: |-
+ The NXP i.MX7 and i.MX8 families contain SoCs that include a MIPI CSI-2
+ receiver IP core named CSIS. The IP core originates from Samsung, and may be
+ compatible with some of the Exynos4 and S5P SoCs. i.MX7 SoCs use CSIS version
+ 3.3, and i.MX8 SoCs use CSIS version 3.6.3.
+
+ While the CSI-2 receiver is separate from the MIPI D-PHY IP core, the PHY is
+ completely wrapped by the CSIS and doesn't expose a control interface of its
+ own. This binding thus covers both IP cores.
