[PATCH 0/3] Enable venus on Fairphone 5 / non-ChromeOS sc7280 venus support

[Luca Weiss]

Devices with Qualcomm firmware (compared to ChromeOS firmware) need some
changes in the venus driver and dts layout so that venus can initialize.

Do these changes, similar to sc7180.

[PATCH 1/3] media: venus: core: Set up secure memory ranges for SC7280

[Luca Weiss]

Not all SC7280 devices ship with ChromeOS firmware. Other devices need
PAS for image authentication. That requires the predefined virtual
address ranges to be passed via scm calls. Define them to enable Venus
on non-CrOS SC7280 devices.

The media tree (or at least venus) moves quite slugglishly..

But looks like applying just the DT patches (which I expect to get
in first) results in a non-platform-killing:

[   25.851120] qcom-venus aa00000.video-codec: Adding to iommu group 11
[   25.851618] qcom-venus aa00000.video-codec: non legacy binding
[   25.916562] qcom-venus aa00000.video-codec: invalid setting for UC_REGION
[   25.916569] qcom-venus aa00000.video-codec: failed to reset venus core
[   25.919000] qcom-venus: probe of aa00000.video-codec failed with error -22

So it should be okay either way.

[PATCH 2/3] arm64: dts: qcom: sc7280: Move video-firmware to chrome-common

[Luca Weiss]

If the video-firmware node is present, the venus driver assumes we're on
a non-TZ system. Move the video-firmware node to chrome-common.dtsi so
we can use venus on a TZ board.

At the same time let's disable the venus node by default as is custom on
such nodes.

On a system that doesn't use TZ for kickstarting Venus

Chrome devices have something running in EL3, so TZ is present,
just not the standard qcom one that we've grown to.. love..

 Move the video-firmware node to chrome-common.dtsi so
> we can use venus on a TZ board.
On non-Chrome boards

I think that's not what you tried to say
