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

While the CSI-2 receiver is separate from the MIPI D-PHY IP core, the PHY is
