8a09bb1be6 media: intel/ipu6: Don't re-allocate memory for firmware
The ipu6 driver allocated vmalloc memory for the firmware if
request_firmware() somehow managed not to use vmalloc to allocate it.

Still how the memory is allocated by request_firmware() is not specified
in its API, so be prepared for kmalloc-allocated firmware, too. Instead of
allocating new vmalloc-backed buffer for the firmware, obtain the pages
from virtual addresses instead.

b71f777d89 media: intel/ipu6: add syscom interfaces between firmware and driver
Syscom is an inter-process(or) communication mechanism between an IPU and
host. Syscom uses message queues for message exchange between IPU and
host. Each message queue has its consumer and producer, host queue
messages to firmware as the producer and then firmware to dequeue the
messages as consumer and vice versa. IPU and host use shared registers or
memory to reside the read and write indices which are updated by consumer
and producer.

fb16c04a53 media: ipu-bridge: Change ov2740 link-frequency to 180 MHz
The only known devices that use an ov2740 sensor in combination with
the ipu-bridge code are various Lenovo ThinkPad models, which all
need the link-frequency to be 180 MHz for things to work properly.

The ov2740 driver used to only support 360 MHz link-frequency,
which is why the ipu-bridge entry used 360 MHz, but now the
ov2740 driver has been extended to also support 180 MHz.

The ov2740 is actually used with 360 MHz link-frequency on Chromebooks.
On Chromebooks the camera/sensor fwnode graph is part of the ACPI tables.
The ipu-bridge code is used to dynamically generate the graph when it is
missing, so it is not used on Chromebooks and the ov2740 will keep using
360 MHz link-frequency there as before.

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.

The V4L2 subdev .get_fmt() and .set_fmt() pad operation handlers have a
short documentation block that merely duplicates information from the
V4L2 subdev API documentation. They offer no value, and are prone to
bit-rotting as shown by the @cfg parameter documentation being outdated.

Pull media updates from Mauro Carvalho Chehab:

 - the old V4L2 core videobuf kAPI was finally removed. All media
   drivers should now be using VB2 kAPI

 - new automotive driver: mgb4

 - new platform video driver: npcm-video

 - new sensor driver: mt9m114

 - new TI driver used in conjunction with Cadence CSI2RX IP to bridge
   TI-specific parts

 - ir-rx51 was removed and the N900 DT binding was moved to the
   pwm-ir-tx generic driver

 - drop atomisp-specific ov5693, using the upstream driver instead

 - the camss driver has gained RDI3 support for VFE 17x

 - the atomisp driver now detects ISP2400 or ISP2401 at run time. No
   need to set it up at build time anymore

 - lots of driver fixes, cleanups and improvements

1d4c25854a media: ipu-bridge: Add missing acpi_dev_put() in ipu_bridge_get_ivsc_acpi_dev()
In ipu_bridge_get_ivsc_acpi_dev(), the "ivsc_adev" acpi_device pointer
from the outer loop is handed over to the caller, which takes proper
care of its reference count.
However, the "consumer" acpi_device pointer from the inner loop is lost,
without decrementing its reference count.

Fix this by adding the missing call to acpi_dev_put().

4670c8c3fb media: ipu-bridge: Fix Kconfig dependencies
The current Kconfig symbol dependencies allow having the following Kconfig
symbol values

	CONFIG_IPU_BRIDGE=m
	CONFIG_VIDEO_IPU3_CIO2=y
	CONFIG_CIO2_BRIDGE=n

This does not work as the IPU bridge API is conditional to
IS_ENABLED(CONFIG_IPU_BRIDGE). Fix this by changing the dependencies so
that CONFIG_IPU_BRIDGE can be separately selected.

The CONFIG_CIO2_BRIDGE symbol becomes redundant as a result and is
removed.

6966f2f7ab media: ivsc: ace: probe ace device after IPU bridge is initialized.
During probe ivsc ace device, acpi_dev_clear_dependencies() will be
called to clear the consumer and supplier relationship between camera
sensor device and ivsc device. But IPU bridge will setup the connection
swnodes for ivsc device and camera sensor device based on this consumer
and supplier relationship. This patch defers ivsc ace's probe to make
sure IPU bridge is initialized before this consumer and supplier
relationship between camera sensor device and IVSC device is cleared.
