Subject: Re: [PATCH v3 5/5] hisilicon/dts: Add hi655x pmic dts node

Mark,
 +- regulator-vset-regs: Voltage set register offset.
 +- regulator-vset-mask: voltage set control mask.
 +- regulator-n-vol: The num of support voltages.
 +- regulator-vset-table: The table of support voltages.

You mentioned in previous version,I I have some questions for it.

This regulator-vset-regs etc are vendor specific describe. The hi655x PMIC
is a series of chips. They all have this value, but the offset may be different.
And we can generate the dts file from excel which is defined by SOC.

I think the dts is designed to distinguish different platform. If we hard code this
in files, it may be also different to use as common in next chip version.

I will appreciate it if you can give me some suggestions.
