With this change we can do things like this update file:
add reg carrizo.smu80.ixSMUSVI_NB_CURRENTVID smc 0xD8230044
add bit carrizo.smu80.ixSMUSVI_NB_CURRENTVID.CURRENT_NB_VID 24 31
add reg carrizo.smu80.ixSMUSVI_GFX_CURRENTVID smc 0xD8230048
add bit carrizo.smu80.ixSMUSVI_GFX_CURRENTVID.CURRENT_GFX_VID 24 31
Which allows us to read powerplay voltage sensors:
smu80.ixSMUSVI_NB_CURRENTVID => 0x6d000000
.CURRENT_NB_VID[24:31] ==
109 (0x0000006d)
smu80.ixSMUSVI_GFX_CURRENTVID => 0x69000000
.CURRENT_GFX_VID[24:31] ==
105 (0x00000069)
Which correspond to 3.475V NB voltage for instance...
