From: Fabio Estevam <[email protected]>
The JPEG decoder/encoder present in iMX8QXP and iMX8QM SoCs need
the PER and IPG clocks to be functional, so add the clock entries.
This also fixes the following schema warning:
imx8qm-apalis-eval.dtb: jpegdec@58400000: 'assigned-clock-rates', 'assigned-clocks', 'clock-names', 'clocks' do not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/media/nxp,imx8-jpeg.yaml#

Changes since v3:
- Add items for clocks (per Krzysztof's feddback)
- Add description for clocks (per Conor's feddback to the other similar patch from Alexander)
- Add "media:" to the subject
- Add Mirela's signed-off
- For the similar patches that were sent for this issue, should Co-developed-by/Signed-off-by be added? Alexander Stein? Frank Li?
Changes since v2:
- Remove clock-names. (Mirela)

Please correct subject. You already got comments on this.

Where? It was there before, so what did you change?

Description is now redundant, drop it.

Sorry I missed that.
I will update the prefix to "media: dt-bindings: nxp,imx8-jpeg:". as you
suggested in v2.

I started from v3 here:
https://lore.kernel.org/linux-devicetree/[email protected]/
The subject was: "[PATCH v3 1/3] dt-bindings: imx8-jpeg: Add clocks
entries", I had just added "media:". Anyways, will update it again.

Ok, I will do so in v5.
Thanks a lot for feedback,
Mirela
