[PATCH v2 0/3] media: rockchip: add driver for the rockchip mipi csi-2 receiver

[Michael Riesch via B4 Relay <devnull+michael.riesch.collabora.com@kernel.org>]

Habidere,

This series adds support for the Rockchip MIPI CSI-2 Receiver that is
integrated into recent Rockchip SoCs, such as the RK3568 and the RK3588.

These changes have been discussed and reviewed thoroughly in roughly 10
iterations of the rkcif patch series (see [0] and predecessors). Thus,
they should be ready for inclusion in mainline.

However, as has been discussed in [0], it would be beneficial to add
support for the split mode (a feature of the Rockchip CSI-2 DPHY)
before integrating the MIPI CSI-2 Receiver into the respective SoC
device tree includes. We can readily add the DT binding and the driver
as I am positive they will not need to be changed when this feature is
introduced, but there are no patches in the series that introduce the
DT nodes.

This constitutes a small step towards mainline video capture and camera
support on the Rockchip RK3588.

Looking forward to your comments!
