applied this series on top of linux-next and build it with 
arm/multi_v7_defconfig plus the following:

CONFIG_BCM_VIDEOCORE=y
CONFIG_BCM2835_VCHIQ=m
CONFIG_VCHIQ_CDEV=y
CONFIG_SND_BCM2835=m
CONFIG_VIDEO_BCM2835=m
CONFIG_BCM2835_VCHIQ_MMAL=m

and the devices doesn't register on Raspberry Pi 3 B Plus:

[   25.523337] vchiq: module is from the staging directory, the quality 
is unknown, you have been warned.
[   25.541647] bcm2835_vchiq 3f00b840.mailbox: Failed to register
