... and that page is no longer available. Given that, if you really need
support for this chip, you might want to consider adding support for
SY24655 and/or SY24657 since public datasheets are available for those
chips. The EIN and ACCUM_CONFIG registers in those chips match the
definitions in your driver submission, so at least at first glance this
should work.

I noticed that there is also SY24656, which appears to be register compatible
to INA226/INA230.

Thanks,
