[PATCH v2 0/2] arm64: dts: imx8mp: Enable CSIS and ISI in DT

[Laurent Pinchart]

Hello,

This small patch series adds the CSIS and ISI devices in the i.MX8MP DT
to support cameras. The ISI DT bindings have just been merged and will
appear in v6.4, making this series a candidate for v6.5.

With these two patches, a board overlay can enable camera support by
instantiating the camera sensor, connecting it to a CSIS instance, and
enabling the CSIS and ISI nodes. The camera pipeline is supported by
V4L2 drivers.
