-  This is the device node for the MIPI CSI-2 receiver core in i.MX7 soc. It is
-  compatible with previous version of samsung d-phy.
+description: |-
+  The NXP i.MX7 SoC family includes a MIPI CSI-2 receiver IP core, documented
+  as "CSIS V3.3". The IP core seems to originate from Samsung, and may be
+  compatible with some of the Exynos4 ad S5P SoCs.
+
+  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.
