Supporting SIDs greater than 9 required additional handling in order to
properly generatae hex values. Apply this customization to pm8150.dtsi.

Same comment as for previous patches - all undefs must be gone.

Maybe I should not have acked all these changes customized SID ("include
sid into defines") because it looks like it opened can of worms.

Best regards,
Krzysztof

All decimal numbers can be represented as hex numbers..
Is there any point to keeping them separate?

Yes, to have pmic@c rather than pmic@12 for USID = 12 = 0xc.

This means that we can not include two copies of the same PMIC (which
do have on both platforms).

I think this can of worms is still better than imperfect duplication.

Consider spi15 and spi16:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/qcom/sm8250.dtsi?h=v6.3-rc5&id=7e364e56293bb98cae1b55fd835f5991c4e96e7d#n1045

Do you see it written as #include "qcom-sm8250-spi.dtsi" with
parametrizing the reg/unit address, interrupts etc?

No. Neither PMIC should be. It is not a special device.

Best regards,
Krzysztof

I think there should be balance. PMICs are complex structures.
Possibly schema will help here once it is in a more enforced mode.
