Subject: [PATCH v6 1/2] media: dt-bindings: nxp,imx8-jpeg: Add clocks entries
Date: Mon,  8 Apr 2024 15:06:53 +0300	[thread overview]
Message-ID: <20240408120654.1196880-1-mirela.rabulea@nxp.com> (raw)

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)
