The patch series used to enable secure video playback (SVP) on MediaTek
hardware in the Linux kernel.

secure memory - Memory allocated in the TEE (Trusted Execution
Environment) which is inaccessible in the REE (Rich Execution
Environment, i.e. linux kernel/user space).

Getting the physical address with sg_dma_address for restricted memory,

to bypass continuous checking for restricted memory.

This allows drivers who don't want to create their own
DMA-BUF exporter to be able to allocate DMA-BUFs directly
from existing DMA-BUF Heaps.
There is some concern that the premise of DMA-BUF heaps is
that userland knows better about what type of heap memory
is needed for a pip
From: John Stultz
Add proper reference counting on the dma_heap structure. While
existing heaps are built-in, we may eventually have heaps loaded
from modules, and we'll need to be able to properly handle the

The docs for dma_heap_get_name were incorrect, and since they were
duplicated in the header they were wrong there too.
The docs formatting was inconsistent so I tried to make it more
consistent across functions since I'm already in here doing cleanup.

Hi Yunfei,
First a high-level comment:
Adding a new V4L2 uAPI also requires patches to v4l-utils, specifically v4l2-ctl
and v4l2-compliance (i.e. new tests are needed for this flag). This will also
help
you test the driver.

I am trying to test this patchset on my setup, but I cannot get it
working. In case it's relevant, I'm running under HyperV. Any
troubleshooting steps/suggestions would definitely be appreciated.
Thanks!
