[PATCH v2 0/2] Drop clock-frequency from RZ/G3E SMARC snd_rzg3e dts node

[Tommaso Merciai]

Dear All,

This series move #clock-cells from r9a09g047e57-smarc.dts to the snd_rzg3e
node in r9a09g047.dtsi. Also AUDIO_CLKOUT is neither pinmuxed nor consumed
on this board, then clock-frequency into r9a09g047e57-smarc.dts describe
the frequency of an output that does not exist here. The DA7212 MCLK comes
from the on-board versa3 clock generator, then drop this entry from the
r9a09g047e57-smarc.dts.

This fix also addresses the following warning:

sound@13c00000 (renesas,r9a09g047-sound): Unevaluated properties are not
allowed ('clock-frequency' was unexpected)

Found running dtbs_check with -W=1.

Kind regards,
Tommaso

v1->v2:
 - Improved/update cover letter subject and body.
 - Drop v1 patch 1/2 that Drop #clock-cells from required into the bindings
   and instead move #clock-cells to the snd_rzg3e node in r9a09g047.dtsi and
   drop only the clock-frequency entry from r9a09g047e57-smarc.dts.
 - Link to v1: https://lore.kernel.org/all/20260820095742.3094558-1-tommaso.merciai.xr@bp.renesas.com

[PATCH v2 1/2] arm64: dts: renesas: r9a09g047: Move #clock-cells to the RZ/G3E SoC dtsi

[Tommaso Merciai]

The renesas,r9a09g047-sound bindings specified #clock-cells as 0, this
is a SoC property rather than of the board.
The commit 3e23d2548ddb ("arm64: dts: renesas: r9a09g047e57-smarc:
Add DA7212 audio codec support") place this entry into the RZ/G3E SMARC
EVK board dts which is wrong.

Move #clock-cells from r9a09g047e57-smarc.dts to the snd_rzg3e node in
r9a09g047.dtsi.

[PATCH v2 2/2] arm64: dts: renesas: r9a09g047e57-smarc: Drop AUDIO_CLKOUT clock-frequency

[Tommaso Merciai]

AUDIO_CLKOUT is neither pinmuxed nor consumed on this board,
clock-frequency describe the frequency of an output that does not
exist here. The DA7212 MCLK comes from the on-board versa3 clock
generator.

Drop the clock-frequency entry from the snd_rzg3e node.

This fix also the following dtbs_check warning:

sound@13c00000 (renesas,r9a09g047-sound): Unevaluated properties are not allowed ('clock-frequency' was unexpected)
	from schema $id: http://devicetree.org/schemas/sound/renesas,r9a09g047-sound.yaml#

8KHz arecord is failing with this change and currently investigating the issue.
Will update you the findings later.


Kind regards,
Tommaso
