Soc framework exposed sysfs entries are not sufficient for some of the h/w platforms. Currently there is no interface where soc drivers can expose further information about their SoCs via soc framework. This change address this limitation where clients can pass their custom entries as attribute group and soc framework would expose them as sysfs properties.
