Support for Broadcom VideoCore services including
the BCM2835 family of products which is used
by the Raspberry PI.

imply VCHIQ_CDEV
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.
if BCM2835_VCHIQ
config VCHIQ_CDEV
bool "VCHIQ Character Driver"
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'.
