help
- Broadcom BCM2835 and similar SoCs have a VPU called VideoCore. This config
- enables the VCHIQ driver, which implements a messaging interface between
- the kernel and the firmware running on VideoCore. Other drivers use this
- interface to communicate to the VPU. More specifically, the VCHIQ driver is
- used by audio/video and camera drivers as well as for implementing MMAL
- API, which is in turn used by several multimedia services on the BCM2835
- family of SoCs.
- Defaults to Y when the Broadcom Videocore services are included in
- the build, N otherwise.

help
- Enable the creation of VCHIQ character driver. The cdev exposes ioctls used
- by userspace libraries and testing tools to interact with VideoCore, via
- the VCHIQ core driver (Check BCM2835_VCHIQ for more info).
- This can be set to 'N' if the VideoCore communication is not needed by
- userspace but only by other kernel modules (like bcm2835-audio). If not
- sure, set this to 'Y'.
