effect in device timing and likely also in power consumption.
CCS static data
---------------
The MIPI CCS driver supports CCS static data for all compliant devices,
including not just those compliant with CCS 1.1 but also CCS 1.0 and SMIA(++).
For CCS the file names are formed as
ccs/ccs-sensor-vvvv-mmmm-rrrr.fw (sensor) and
ccs/ccs-module-vvvv-mmmm-rrrr.fw (module).
For SMIA++ compliant devices the corresponding file names are
ccs/smiapp-sensor-vv-mmmm-rr.fw (sensor) and
ccs/smiapp-module-vv-mmmm-rrrr.fw (module).
For SMIA (non-++) compliant devices the static data file name is
ccs/smia-sensor-vv-mmmm-rr.fw (sensor).
vvvv or vv denotes MIPI and SMIA manufacturer IDs respectively, mmmm model ID
and rrrr or rr revision number.
