[PATCH 0/2] Make AUDIO_CLKOUT optional and drop it from RZ/G3E SMARC

From: Tommaso Merciai

Dear All,

This series makes #clock-cells optional in the renesas,r9a09g047-sound
binding, since the node acts as a clock provider only on boards that
route AUDIO_CLKOUT, and drops the corresponding AUDIO_CLKOUT properties
from r9a09g047e57-smarc.dts, where the pin is neither pinmuxed nor
consumed. The DA7212 MCLK comes from the on-board versa3.

This fix also addresses the following warning:

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

Spotted running dtbs_check with -W=1.

Kind regards,
Tommaso
