13 The VCHIQ communication channel can be provided by BCM283x and Capri SoCs,
22 - brcm,bcm2835-vchiq
27 - brcm,bcm2836-vchiq

20 enables the VCHIQ driver, which implements a messaging interface between
22 interface to communicate to the VPU. More specifically, the VCHIQ driver is
32 bool "VCHIQ Character Driver"
34 Enable the creation of VCHIQ character driver. The cdev exposes ioctls used
36 the VCHIQ core driver (Check BCM2835_VCHIQ for more info).

| D | TESTING | 1 This document contains some hints to test the function of the VCHIQ driver
6 Testing the VCHIQ driver requires a Raspberry Pi with one of the following SoC:
14 There are no specific requirements to the VideoCore firmware to get VCHIQ
26 Just use bcm2835_defconfig which already has VCHIQ enabled.
30 Use the multi_v7_defconfig as a base and then enable all VCHIQ options.
34 Use the defconfig as a base and then enable all VCHIQ options.
40 Check the driver is probed and /dev/vchiq is created
