Pull media updates from Mauro Carvalho Chehab:

 - v4l core: subdev frame interval now supports which field

 - v4l kapi: moves and renames the init_cfg pad op to init_state as an
   internal op.

 - new sensor drivers: gc0308, gc2145, Avnet Alvium, ov64a40, tw9900

 - new camera driver: STM32 DCMIPP

 - s5p-mfc has gained MFC v12 support

 - new ISP driver added to staging: Starfive

 - new stateful encoder/decoded: Wave5 codec It is found on the J721S2
   SoC, JH7100 SoC, ssd202d SoC. Etc.

 - fwnode gained support for MIPI "DisCo for Imaging"
   (https://www.mipi.org/specifications/mipi-disco-imaging)

 - as usual, lots of cleanups, fixups and driver improvements.

+Starfive Camera Subsystem driver
+================================
+
+Introduction
+------------
+
+This file documents the driver for the Starfive Camera Subsystem found on
+Starfive JH7110 SoC. The driver is located under drivers/staging/media/starfive/
+camss.
+
+The driver implements V4L2, Media controller and v4l2_subdev interfaces. Camera
+sensor using V4L2 subdev interface in the kernel is supported.
+
+The driver has been successfully used on the Gstreamer 1.18.5 with v4l2src
+plugin.

+- MIPI: The MIPI interface, receiving data from a MIPI CSI-2 camera sensor.
+
+- Parallel: The parallel interface,  receiving data from a parallel sensor.
+
+- ISP: The ISP, processing raw Bayer data from an image sensor and producing
+  YUV frames.
+
+
+Topology
+--------
+
+The media controller pipeline graph is as follows:

+
+.. kernel-figure:: starfive_camss_graph.dot
+    :alt:   starfive_camss_graph.dot
+    :align: center
+
+The driver has 2 video devices:
+
+- capture_raw: The capture device, capturing image data directly from a sensor.
+- capture_yuv: The capture device, capturing YUV frame data processed by the
+  ISP module
+
+The driver has 3 subdevices:
+
+- stf_isp: is responsible for all the isp operations, outputs YUV frames.
+- cdns_csi2rx: a CSI-2 bridge supporting up to 4 CSI lanes in input, and 4
+  different pixel streams in output.
+- imx219: an image sensor, image data is sent through MIPI CSI-2.
