Merge tag 'media/v4.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - remove of atomisp driver from staging, as nobody would have time to
   dedicate huge efforts to fix all the problems there. Also, we have a
   feeling that the driver may not even run the way it is.

 - move Zoran driver to staging, in order to be either fixed to use VB2
   and the proper media kAPIs or to be removed

 - remove videobuf-dvb driver, with is unused for a while

 - some V4L2 documentation fixes/improvements

 - new sensor drivers: imx258 and ov7251

 - a new driver was added to allow using I2C transparent drivers

 - several improvements at the ddbridge driver

 - several improvements at the ISDB pt1 driver, making it more coherent
   with the DVB framework

 - added a new platform driver for MIPI CSI-2 RX: cadence

 - now, all media drivers can be compiled on x86 with COMPILE_TEST

 - almost all media drivers now build on non-x86 architectures with
   COMPILE_TEST

 - lots of other random stuff: cleanups, support for new board models,
   bug fixes, etc

+Renesas R-Car MIPI CSI-2
+------------------------
+
+The R-Car CSI-2 receiver device provides MIPI CSI-2 capabilities for the
+Renesas R-Car family of devices. It is used in conjunction with the
+R-Car VIN module, which provides the video capture capabilities.
+
+Mandatory properties
+--------------------
+ - compatible: Must be one or more of the following
+   - "renesas,r8a7795-csi2" for the R8A7795 device.
+   - "renesas,r8a7796-csi2" for the R8A7796 device.
+   - "renesas,r8a77965-csi2" for the R8A77965 device.
+   - "renesas,r8a77970-csi2" for the R8A77970 device.
+
+ - reg: the register base and size for the device registers
+ - interrupts: the interrupt for the device
+ - clocks: reference to the parent clock
+
+The device node shall contain two 'port' child nodes according to the
+bindings defined in Documentation/devicetree/bindings/media/
+video-interfaces.txt. port@0 shall connect to the CSI-2 source. port@1
+shall connect to all the R-Car VIN modules that have a hardware
+connection to the CSI-2 receiver.
+
+- port@0- Video source (mandatory)
+	- endpoint@0 - sub-node describing the endpoint that is the video source
+
+- port@1 - VIN instances (optional)
+	- One endpoint sub-node for every R-Car VIN instance which is connected
+	  to the R-Car CSI-2 receiver.
+
+Example:
+
