The WM8962 is configured so the SoC is driving the clock, and it's
currently set to 24 MHz. However, when playing audio it shows the
following message:
wm8962 5-001a: Unsupported sysclk ratio 500

While not harmful, a better clock ratio is 512. It makes the
message disappear, and it still plays sound.

arm64: dts: renesas: beacon-renesom: Fix gpio expander reference

The board used to originally introduce the Beacon Embedded RZ/G2[M/N/H]
boards had a GPIO expander with address 20, but this was changed when
the final board went to production.

The production boards changed both the part itself and the address.
With the incorrect address, the LCD cannot come up. If the LCD fails,
the rcar-du driver fails to come up, and that also breaks HDMI.

Pre-release board were not shipped to the general public, so it should
be safe to push this as a fix. Anyone with a production board would
have video fail due to this GPIO expander change.

arm64: boot: dts: r8a774[a/b/e]1-beacon: Consolidate sound clocks

Each kit-level file represents a SOM + baseboard for a specific
SoC type and uses specific clocks unique to each SoC. With the
exception of one clock, the rest of the clock info was duplicated.

There is a generic clock called CPG_AUDIO_CLK_I defined in each of
the SoC DTSI files which points to this unique clock. By using that,
the clock information for the rcar_sound can be consolidated into
the baseboard file and have it reference this generic clock thus
removing the duplication from the three variants.

Most of the clock related dt-binding header files are located in

This was discovered while investigating the state of ownership of the
