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

tristate "BCM2835 VCHIQ"
depends on HAS_DMA

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'.
