The do_crop flag indicates whether a cropping rectangle has been set.
Instead of storing this flag separately in each file handle, move do_crop
to struct bttv in preparation for vb2 conversion which stops using
separate bttv file handles.

In preparation for the vb2 conversion, copy the vbi format from struct
bttv_fh and add it to the main struct bttv. Use vbi format from struct
bttv wherever it will be needed after the vb2 conversion which stops using
separate bttv file handles altogether. To avoid changing more code than
necessary, just leave the vbi format in separate file handles wherever it
will be subsequently removed by vb2.

Use a v4l2_fh when opening a radio device instead of a bttv_fh and manage
it with v4l2_fh_open() and v4l2_fh_release() and v4l2_ctrl_poll(). This

Previously on ACPI platforms, sensors that are intended to be connected
to an IPU device for use with the ipu3-cio2 driver lacking the necessary
connection information in firmware. IPU bridge driver is to connect
sensors to IPU device via software nodes.
Currently IVSC located between IPU device and sensors is available in
existing commercial platforms from multiple OEMs. But the connection
information between them in firmware is also not enough to build V4L2
connection graph. This patch parses the connection properties from the
SSDB buffer in DSDT and build the connection using software nodes.
IVSC driver is based on MEI framework (previously known as HECI), it
has two MEI clients, MEI CSI and MEI ACE. Both clients are used to
communicate messages with IVSC firmware. Linux abstracts MEI client
as a device, whose bus type is MEI. And the device is addressed by a
GUID/UUID which is part of the device name of MEI client. After figured
out MEI CSI via the UUID composed device name, this patch setup the
connection between MEI CSI and IPU, and the connection between MEI CSI
and sensor via software nodes.

ACE is a submodule of IVSC which controls camera sensor's
ownership, belonging to host or IVSC. When IVSC owns camera
sensor, it is for algorithm computing. When host wants to
control camera sensor, ACE module needs to be informed of
ownership with defined interface.
The interface is via MEI. There is a separate MEI UUID, which
this driver uses to enumerate.
To switch ownership of camera sensor between IVSC and host,
the caller specifies the defined ownership information which
will be sent to firmware by sending MEI command.
Device link(device_link_add) is used to set the right camera
sensor ownership before accessing the sensor via I2C. With
DL_FLAG_PM_RUNTIME and DL_FLAG_RPM_ACTIVE, the supplier device
will be PM runtime resumed before the consumer(camera sensor).
So use runtime PM callbacks to transfer the ownership between
host and IVSC.

CSI is a submodule of IVSC which can route camera sensor data
to the outbound MIPI CSI-2 interface.
The interface communicating with firmware is via MEI. There is
a separate MEI UUID, which this driver uses to enumerate.
To route camera sensor data to host, the information of link
frequency and number of data lanes is sent to firmware by
sending MEI command when starting stream.
CSI also provides a privacy mode. When privacy mode is turned
on, camera sensor can't be used. This means that both IVSC and
host Image Processing Unit(IPU) can't get image data. And when
this mode is turned on, user is notified via v4l2 control
callback.

In most cases when a VCM is used there is a single integrated module
with the sensor + VCM + lens. This means that the sensor and VCM often
share regulators and possibly also something like a powerdown pin.
In the ACPI tables this is modelled as a single ACPI device with
multiple I2cSerialBus resources.
On atomisp devices the regulators and clks are modelled as ACPI
power-resources, which are controlled by the (ACPI) power state
of the sensor. So the sensor must be in D0 power state for the VCM
to work.
To make this work add a device-link with DL_FLAG_PM_RUNTIME flag
so that the sensor will automatically be runtime-resumed whenever
the VCM is runtime-resumed.
This requires the probing of the VCM and thus the creation of the VCM
I2C-client to be delayed till after the sensor driver has bound.
Move the instantiation of the VCM I2C-client to the v4l2_async_notifier
bound op, so that it is done after the sensor driver has bound; and
add code to add the device-link.
This fixes the problem with the shared ACPI power-resources on atomisp2
and this avoids the need for VCM related workarounds on IPU3 / IPU6.
E.g. until now the dw9719 driver needed to get and control a Vsio
(V sensor IO) regulator since that needs to be enabled to enable I2C
pass-through on the PMIC on the sensor module. So the driver was
controlling this regulator even though the actual dw9719 chip has no
Vsio pin / power-plane.
This also removes the need for ipu_bridge_init() to return
-EPROBE_DEFER since the VCM is now instantiated later.

The code to go from ACPI sensor info to a fwnode-tree with connector
nodes and endpoint properties is 99% the same for the atomisp2 and
the IPU3.
The main difference is that atomisp2 devices do not have a SSDB table
with various info.
Abstract out the parsing of the sensor's ACPI fwnode into a helper
function and store the parsed results, rather then the raw SSDB
in struct ipu_sensor.
This is a preparation patch for making the ipu-bridge code more generic
so that it can be shared with the atomisp driver.

Store the dev pointer in struct ipu_bridge instead of passing it
around 3 levels deep.
This takes up slightly more memory but further patches in this series
add more data which needs to be passed around making passing
everything as arguments cumbersome and those further patches also
add data to struct ipu_bridge.
To be consistent with these upcoming patches also add
the dev pointer to struct ipu_bridge.

Commit 567f97bd381f ("media: ipu3-cio2: support multiple sensors and VCMs
with same HID") introduced an on stack vcm_name and then uses this for
the name field of the software_node struct used for the vcm.
But the software_node struct is much longer lived then the current
stack-frame, so this is no good.
Instead extend the ipu_node_names struct with an extra field to store
the vcm software_node name and use that.
Note this also changes the length of the allocated buffer from
ACPI_ID_LEN + 4 to 16. the name is filled with "<ipu_vcm_types[x]>-%u"
where ipu_vcm_types[x] is not an ACPI_ID. The maximum length of
the strings in the ipu_vcm_types[] array is 11 + 5 bytes for "-255\0"
means 16 bytes are needed in the worst case scenario.

This code was previously part of the VIDEO_IPU3_CIO2 driver, which could
be built-in or a loadable module, but after the move it turned into a
builtin-only driver. This fails to link when the I2C subsystem is a
module:
x86_64-linux-ld: drivers/media/pci/intel/ipu-bridge.o: in function `ipu_bridge_unregister_sensors':
ipu-bridge.c:(.text+0x50): undefined reference to `i2c_unregister_device'
x86_64-linux-ld: drivers/media/pci/intel/ipu-bridge.o: in function `ipu_bridge_init':
ipu-bridge.c:(.text+0x9c9): undefined reference to `i2c_acpi_new_device_by_fwnode'
In general, drivers should not have to be built-in, so change the option
to a tristate with the corresponding dependency. This in turn opens a
new problem with the dependency, as the IPU bridge can be a loadable module
while the ipu3 driver itself is built-in, producing a new link failure:
86_64-linux-ld: drivers/media/pci/intel/ipu3/ipu3-cio2.o: in function `cio2_pci_probe':
ipu3-cio2.c:(.text+0x197e): undefined reference to `ipu_bridge_init'
In order to fix this, restore the old Kconfig option that controlled
the ipu bridge driver before it was split out, but make it select a
hidden symbol that now corresponds to the bridge driver.
When other drivers get added that share ipu-bridge, this should cover
all corner cases, and allow any combination of them to be built-in
or modular.

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.

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().

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them.

If 'done' is not NULL, then next can never be NULL, so just drop
the 'next' check.
This fixes this smatch warning:
drivers/media/pci/tw686x/tw686x-audio.c:62 tw686x_audio_irq() warn: can 'next' even be NULL?

One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element arrays with flexible-array
members in struct vbi_anc_data.
This results in no differences in binary output.

The argument of the to_sensor_asd() is called the same as the field name
for the container_of() macro, so it only works if the argument name is
"asd". Fix it.
Also switch to container_of_const().

IRQ handler netup_spi_interrupt() takes spinlock spi->lock. The lock
is initialized in netup_spi_init(). However, irq handler is registered
before initializing the lock.
Spinlock dma->lock and i2c->lock suffer from the same problem.
Fix this by registering the irq at the end of probe.

When Universal DVB card is detaching, netup_unidvb_dma_fini()
uses del_timer() to stop dma->timeout timer. But when timer
handler netup_unidvb_dma_timeout() is running, del_timer()
could not stop it. As a result, the use-after-free bug could
happen. The process is shown below:
(cleanup routine) | (timer routine)
| mod_timer(&dev->tx_sim_timer, ..)
netup_unidvb_finidev() | (wait a time)
netup_unidvb_dma_fini() | netup_unidvb_dma_timeout()
del_timer(&dma->timeout); |
| ndev->pci_dev->dev //USE
Fix by changing del_timer() to del_timer_sync().
