This adds support for Intel Visual Sensing Controller (IVSC).
- Enables the IVSC firmware services required for controlling
- camera sensor ownership and CSI-2 link through Image Processing
- Unit(IPU) driver of Intel.
+ The IVSC support is split into two devices, ACE (Algorithm
+ Context Engine) and CSI (Camera Serial Interface), each of which
+ have their own drivers. The ACE is used to select the ownership
+ of the sensor between the IVSC and the host CPU while the CSI is
+ used to both select the routing destination for the data the
+ sensor transmits over the CSI-2 bus between the IVSC and the
+ host CPU and to configure the CSI-2 bus itself.
+
+ The modules will be called ivsc-ace and ivsc-csi.
