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
