From: Mirela Rabulea <[email protected]>
Add the dts files for i.MX8QM/QXP JPEG codec (previous patch was v12).
The bindings for i.MX8QXP were already upstream, add i.MX8QM compatible,
this is a new patch.
Mirela Rabulea (2):
media: dt-bindings: imx-jpeg: Add compatible for i.MX8QM JPEG codec

2.17.1
From: Mirela Rabulea <[email protected]>
Add two more compatibles: "nxp,imx8qm-jpgdec" and " nxp,imx8qm-jpgenc".
Also update the compatible property to ensure mutually exclusive usage of
encoder and decoder compatibles.
Update examples.

I might wish to avoid using anyOF for jpeg cases and defined in a more
Straightforward way.
e.g.
properties:
compatible:
oneOf:
- items:
- enum:
# JPEG decoder
- nxp,imx8qxp-jpgdec
# JPEG encoder
- nxp,imx8qxp-jpgenc
- items:
- enum:
- nxp,imx8qm-jpgdec
- const: nxp,imx8qxp-jpgdec
- items:
- enum:
- nxp,imx8qm-jpgenc
- const: nxp,imx8qxp-jpgenc
Could you check if it works?

Node should be disabled by default.

At version v5 of this patch, the node was disabled by default, and I
received this feedback from Ezequiel Garcia:
"Pure memory-to-memory are typically not enabled per-board, but just
per-platform.
So you can drop the disabled status here."
So, in v6 I made it enabled by default.
Any strong reasons for enabled/disabled per platform?

AFAIK we usually only enable system basic features and let other
user selectable features disabled by default in dts.
Even for device LPCG clocks, if it's enabled by default and later
enter runtime suspend if no users, it still consumes power.

Well-written drivers shouldn't draw any power if not used.
And DT is about hardware-description, not about usage-description.
Which means, at the soc.dtsi level you disable devices that need
some board-level hardware thing to be enabled (e.g. a physical
connected, a regulator, etc.).
A pure memory-to-memory should be enabled by default, because
in practice you can't predict what the users a board will want
to use, nor the DT is the place for that.
Sticking to hardware description is the best way to get DT right :-)

LPCG won't draw power when not used. But the power domain used by LPCG
will still draw power when enter idle state.

It makes sense to me. Thanks
Mirela,
Please follow up with Ezequiel's suggestion.
For LPCGS used by jpeg, you can keep it enabled by default.
