+MIPI CCS camera sensor driver
+=============================
+
+The MIPI CCS camera sensor driver is a generic driver for `MIPI CCS
+<https://www.mipi.org/specifications/camera-command-set>`_ compliant
+camera sensors.
+
+Also see :ref:`the CCS driver UAPI documentation <media-ccs-uapi>`.
+
+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.
+
+CCS tools
+~~~~~~~~~
+
+`CCS tools <https://github.com/MIPI-Alliance/ccs-tools/>`_ is a set of
+tools for working with CCS static data files. CCS tools includes a
+definition of the human-readable CCS static data YAML format and includes a
+program to convert it to a binary.
+
+Register definition generator
+-----------------------------
+
+The ccs-regs.asc file contains MIPI CCS register definitions that are used
+to produce C source code files for definitions that can be better used by
+programs written in C language. As there are many dependencies between the
+produced files, please do not modify them manually as it's error-prone and
+in vain, but instead change the script producing them.
+
+Usage
+~~~~~
+
+Conventionally the script is called this way to update the CCS driver
+definitions:
+
+.. code-block:: none
+
+	$ Documentation/driver-api/media/drivers/ccs/mk-ccs-regs -k \
+		-e drivers/media/i2c/ccs/ccs-regs.h \
+		-L drivers/media/i2c/ccs/ccs-limits.h \
+		-l drivers/media/i2c/ccs/ccs-limits.c \
+		-c Documentation/driver-api/media/drivers/ccs/ccs-regs.asc

+CCS PLL calculator
+==================
+
+The CCS PLL calculator is used to compute the PLL configuration, given sensor's
+capabilities as well as board configuration and user specified configuration. As
+the configuration space that encompasses all these configurations is vast, the
+PLL calculator isn't entirely trivial. Yet it is relatively simple to use for a
+driver.
+
+The PLL model implemented by the PLL calculator corresponds to MIPI CCS 1.1.
