maintainers:

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.
