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
