An empty snps,quirk-frame-length-adjustment won't cause any change
performed by the driver. Moreover the DT schema validation will fail,
since it expects the property being assigned with some value. So just
discard the property declaration then from the example.

Note the same problem is in the DT source file

Thanks for reporting this, actually the fladj must be 0x20 on this hw,
but we do set this on the PHY side, so we can let the dwc3 side 0 here.

I can convert this patch to initializing the "snps,quirk-frame-length-adjustment"
property with 0x20 value instead. Since most likely I'll have to send a v2/v3/etc
of this patchset, that modification won't be too much work to do. What do you think?

Anyway please note, that I've fixed the improper property usage in the DT schema
example only. "snps,quirk-frame-length-adjustment" defined as boolean still
persists in the DTS file: arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi .
So if you ever try to validate that dts file with "make dtbs_check" scenario, it
will fail.

Yes, do this please, anyway it's only an example so it's ok.

Yes, I'll push a fix to pass the dtbs_check when this is merged.

Ok. Shall I preserve your Acked-by tag in the new patch or you'd prefer to
review it first?

> anyway it's only an example so it's ok.

Actually examples are also validated by "make dt_binding_check". That's why I
had to fix the amlogic,meson-g12a-usb-ctrl example for at least so the new
snps,dwc3.yaml DT schema wouldn't break that full DT bindings
validation procedure.)
