16 CCS static data
19 The MIPI CCS driver supports CCS static data for all compliant devices,
20 including not just those compliant with CCS 1.1 but also CCS 1.0 and SMIA(++).
21 For CCS the file names are formed as
23 ccs/ccs-sensor-vvvv-mmmm-rrrr.fw (sensor) and
24 ccs/ccs-module-vvvv-mmmm-rrrr.fw (module).

7 MIPI CCS camera sensor driver
10 The MIPI CCS camera sensor driver is a generic driver for `MIPI CCS
18 Also see :ref:`the CCS driver kernel documentation <media-ccs-driver>`.
66 The MIPI CCS driver implements a number of private controls under
67 ``V4L2_CID_USER_BASE_CCS`` to control the MIPI CCS compliant camera sensors.
72 The CCS defines an analogue gain model where the gain can be calculated using
