+description:
+ This binding provides support for the Vision Processing Unit (VPU) found on
+ the Intel Keem Bay SoC.
+
+ The VPU is started and controlled by SoC CPU, which is in charge of loading
+ the VPU firmware. The SoC CPU can communicate with the VPU firmware using an
+ Inter-Processor Communication (IPC) mechanism.
