+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.
