media: v4l: cadence: Add Cadence MIPI-CSI2 RX driver The Cadence CSI-2 RX Controller is an hardware block meant to be used as a bridge between a CSI-2 bus and pixel grabbers. It supports operating with internal or external D-PHY, with up to 4 lanes, or without any D-PHY. The current code only supports the latter case. It also support dynamic mapping of the CSI-2 virtual channels to the associated pixel grabbers, but that isn't allowed at the moment either.

config VIDEO_CADENCE

help
If you have a media device designed by Cadence, say Y.
Note that this option doesn't include new drivers in the kernel:
saying N will just cause Kconfig to skip all the questions about
Cadence media devices.

media: v4l: cadence: add VIDEO_V4L2 dependency The cadence media drivers can be built-in while the v4l2 core is a loadable module.

It supports operating with an internal or external D-PHY, with up to 4 lanes, or without any D-PHY. The current code only supports the latter case. While the virtual channel input on the pixel interface can be directly mapped to CSI2, the datatype input is actually a selection signal (3-bits) mapping to a table of up to 8 preconfigured datatypes/formats (programmed at start-up) The block supports up to 8 input datatypes.
