From: Fabio Estevam <festevam@denx.de>

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 v5:
- Remove one extra ":" from subject (thanks Fabio!)
- Use <festevam@denx.de> address for both Author and Signed-of (Fabio's feedback)

Changes since v4:
- Remove redundant description and update subject prefix (per Krzysztof's feddback)

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)

This is like third version today? Give people chance to review your code
and wait 24h before postings.

Best regards,

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.
