Hello,
Here is v7 with following comments addressed:
* Move iommu allocate/attach and detach/free to firmware init/deinit
to avoid iommu configurations during every firmware reload.
* Move DT documentation as separate patch.
Stanimir Varbanov (1):
venus: firmware: register separate platform_device for firmware loader
Vikash Garodia (4):
venus: firmware: add routine to reset ARM9
venus: firmware: move load firmware in a separate function
venus: firmware: add no TZ boot and shutdown routine
dt-bindings: media: Document bindings for venus firmware device

This registers a firmware platform_device and associate it with
video-firmware DT subnode. Then calls dma configure to initialize
dma and iommu.

Video hardware is mainly comprised of vcodec subsystem and video
control subsystem. Video control has ARM9 which executes the video
firmware instructions whereas vcodec does the video frame processing.
This change adds support to load the video firmware and bring ARM9
out of reset for platforms which does not have trustzone.
An iommu domain is associated and managed with the firmware device.
