          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.
