5755be5f15 media: v4l2-subdev: Rename .init_cfg() operation to .init_state() 
The subdev .init_cfg() operation is affected by two issues:

- It has long been extended to initialize a whole v4l2_subdev_state
  instead of just a v4l2_subdev_pad_config, but its name has stuck
  around.

- Despite operating on a whole subdev state and not being directly
  exposed to the subdev users (either in-kernel or through the userspace
  API), .init_cfg() is categorized as a subdev pad operation.

This participates in making the subdev API confusing for new developers.
Fix it by renaming the operation to .init_state(), and make it a subdev
internal operation.

bc0e8d91fe media: v4l: subdev: Switch to stream-aware state functions 
Switch all drivers accessing sub-device state to use the stream-aware
functions. We will soon remove the old ones.

Additionally drivers/media/i2c/s5k5baf.c and
drivers/media/platform/samsung/s3c-camif/camif-capture.c have been
manually changed as Coccinelle didn't. Further local variables have been
removed as they became unused as a result of the other changes.

Also Coccinelle introduced indentation by space in files
drivers/media/i2c/st-mipid02.c and
drivers/media/platform/rockchip/rkisp1/rkisp1-isp.c. This has been also
corrected.

Merge tag 'media/v6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913

 - new Intel IVSC MEI drivers

 - some Mediatek platform drivers were moved to a common location

 - Intel atomisp2 driver is now working with the main ov2680 driver. Due
   to that, the atomisp2 ov2680 staging one was removed

 - the bttv driver was finally converted to videobuf2 framework. This
   was the last one upstream using videobuf version 1 core. We'll likely
   remove the old videobuf framework on 6.7

 - lots of improvements at atomisp driver: it now works with normal I2C
   sensors. Several compile-mode dependecies to select between ISP2400
   and ISP2401 are now solved in runtime

 - a new ipu-bridge logic was added to work with IVSC MEI drivers

 - venus driver gained better support for new VPU versions

 - the v4l core async framework has gained lots of improvements and
   cleanups

 - lots of other cleanups, improvements and driver fixes

b8ec754ae4 media: v4l: async: Set v4l2_device and subdev in async notifier init 
Set the v4l2_device already in async notifier init, so struct device
related to it will be available before the notifier is registered. This
requires separating notifier initialisation into two functions, one that
takes v4l2_device as its argument, v4l2_async_nf_init and
v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the
notifier will use a single function, v4l2_async_nf_register.

This is done in order to make struct device available earlier, during
construction of the async connections, for sensible debug prints.

adb2dcd5f2 media: v4l: async: Rename v4l2_async_subdev as v4l2_async_connection 
Rename v4l2_async_subdev as v4l2_async_connection, in order to
differentiate between the sub-devices and their connections: one
sub-device can have many connections but the V4L2 async framework has so
far allowed just a single one. Connections in this context will later
translate into either MC ancillary or data links.

This patch prepares changing that relation by changing existing users of
v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices
themselves will not be needed anymore

Additionally, __v4l2_async_nf_add_subdev() has been renamed
__v4l2_async_nf_add_connection().

cd063027c3 media: imx: Unstage the imx8mq-mipi-csi2 driver 
The imx8mq-mipi-csi2 MIPI CSI-2 receiver driver is used and maintained.
There is no reason to keep it in staging. The accompanying CSI bridge
driver that uses it is in drivers/media/platform/nxp as well.

One TODO is to get rid of csi_state's "state" and "lock" variables.
Especially make sure suspend/resume is working without them. That can
very well be worked on from the new location.

Also add a MAINTAINERS section for the imx8mq-mipi-csi2 mipi receiver
driver.
