No. It may poll sensormodule binarys, register lists are in
sensormodule, the slave addr may be here too.

In qccamfrontsensor_extension8280.cab

CAMF_RES_MTP_ALT.bin
CAMF_RES_MTP.bin
CAMF_RES_QRD.bin
com.qti.sensormodule.hlt_hi846.bin
com.qti.sensormodule.xinli_s5k4h7.bin
com.qti.tuned.default.bin # for hi846
com.qti.tuned.hlt_hi846.bin
com.qti.tuned.xinli_s5k4h7.bin
qccamfrontsensor_extension8280.cat
qccamfrontsensor_extension8280.inf
SCF1_FRONT_MTP.bin
SCFG_FRONT_MTP.bin
SCFG_FRONT_QRD.bin

in SCFG_FRONT_QRD.bin

Package ()
{
    "com.qti.sensormodule.hlt_hi846.bin",
    "com.qti.tuned.hlt_hi846.bin",
    0x0000000000150041,
    0x0000000046080F16, # id, id_addr, this can be found in the binary too
    0x0000000000000000,
},

If this fails, then try to load com.qti.sensormodule.xinli_s5k4h7.bin?

Best wishes,
Pengyu
