/****************************************************************************
 * Octopus CBI Second Source Factory Cache
 *
 * SSFC was introduced after variants were MPed already so we can expect there
 * can be devices in the field without SSFC field in the CBI. For devices
 * without SSFC field in the CBI, the value of SSFC will be 0 set by get_ssfc()
 * in the cbi_ssfc.c.
 *
 * On the other hand, taking audio codec as the example there are two sources -
 * DA7219 and RT5682 used in the MPed devices before introducing SSFC. As a
 * result, the value 0 of each bits group for a specific component is defined as
 * DEFAULT and different variants should transform this DEFAULT to one of
 * sources they used as the first sources. In the example here, either DA7219 or
 * RT5682 should be transformed.
