This function is only called from astbmc_fixup_bmc_sensors() which exists to fix up issues with the hostboot provided FDT on P8. Given we generate the entire DT from the HDAT on P9 I don't really see the point of calling it at all. Could we add a proc_gen check around the call to astbmc_fixup_bmc_sensors() instead?

Makes sense. Fixed in V3. -Vasant

P9 onwards OPAL is building device tree for BMC based system using HDAT. We are populating bmc/compatible node with ast bmc version. Hence do not delete this property.
