Add support for C-PHY on R-Car V4H. While the V4H supports both D-PHY
and C-PHY this patch only adds support for the C-PHY mode due to lack of
documentation and hardware to test on.
The V4H is the first Gen4 device that is enabled in the rcar-csi2
driver. There is much overlap with the Gen3 driver, the primary
difference is in how the receiver is started. The V4H have a much larger
register space and some addresses overlap with Gen3.

The CSI2 specification specifies a standard method to access camera sensor
registers called "Camera Control Interface (CCI)".
This uses either 8 or 16 bit (big-endian wire order) register addresses
and supports 8, 16, 24 or 32 bit (big-endian wire order) register widths.
Currently a lot of Linux camera sensor drivers all have their own custom
helpers for this, often copy and pasted from other drivers.
Add a set of generic helpers for this so that all sensor drivers can
switch to a single common implementation.
These helpers take an extra optional "int *err" function parameter,
this can be used to chain a bunch of register accesses together with
only a single error check at the end, rather than needing to error
check each individual register access. The first failing call will
set the contents of err to a non 0 value and all other calls will
then become no-ops.

Reserved memory can be either looked up using the generic function
of_address_to_resource() or using the special of_reserved_mem_lookup().
The latter has the advantage that it ensures that the referenced memory
region was really reserved and is not e.g. status = "disabled".
of_reserved_mem also supports allocating reserved memory dynamically at
boot time. This works only when using of_reserved_mem_lookup() since
there won't be a fixed address in the device tree.
Switch the code to use of_reserved_mem_lookup(). There is no functional
difference for static reserved memory allocations.

on which the video driver should decide which code paths to take.
Up until now, we've relied on HFI versions instead, but that was just
a happy accident between recent SoCs. Add a field in the res struct
and add correlated definitions that will be used to account for the
aforementioned differences.

As per information from Qualcomm [1], this property is not really
supported beyond msm8916 (HFI V1) and some newer HFI versions really
dislike receiving it, going as far as crashing the device.
Only consider toggling it (via the module option) on HFIV1.
While at it, get rid of the global static variable (which defaulted
to zero) which was never explicitly assigned to for V1.

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.

That was very confusing, and so split this up in a adap_unconfigured()

This also makes it easier to understand when the mutex is held: all
low-level adap_* callbacks are called with the mutex held. All other

A potential deadlock was found by Zheng Zhang with a local syzkaller
instance.
The problem is that when a non-blocking CEC transmit is canceled by calling
cec_data_cancel, that in turn can call the high-level received() driver
callback, which can call cec_transmit_msg() to transmit a new message.
The cec_data_cancel() function is called with the adap->lock mutex held,
and cec_transmit_msg() tries to take that same lock.
The root cause is that the received() callback can either be used to pass
on a received message (and then adap->lock is not held), or to report a
canceled transmit (and then adap->lock is held).
This is confusing, so create a new low-level adap_nb_transmit_canceled
callback that reports back that a non-blocking transmit was canceled.
And the received() callback is only called when a message is received,
as was the case before commit f9d0ecbf56 ("media: cec: correctly pass

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.

When the v4l2-async framework was introduced, the use case for it was to
connect a camera sensor with a parallel receiver. Both tended to be rather
simple devices with a single connection between them.
The framework has been since improved in multiple ways but there are
limitations that have remained, for instance the assumption an async
sub-device is connected towards a single notifier and via a single link
only.
This patch enables connecting a sub-device to one or more notifiers
simultaneously, with one or more connections per notifier. The notifier
information is moved from the sub-device to the connection and the
connections in sub-device are no longer a pointer but a linked list.

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().

V4L2 async sub-device matching originally used the device nodes only.
Endpoint nodes were taken into use instead as using the device nodes was
problematic for it was in some cases ambiguous which link might have been
in question.
There is however no need to use endpoint nodes on both sides, as the async
sub-device's fwnode can always be trivially obtained using
fwnode_graph_get_remote_endpoint() when needed while what counts is
whether or not the link is between two device nodes, i.e. the device nodes
match.
This will briefly break the adv748x driver but it will be fixed later in
the set, by patch "media: adv748x: Return to endpoint matching".

The v4l2_async_nf_parse_fwnode_endpoints() function, part of
v4l2-fwnode.c, was a helper meant to register one async sub-dev for each
fwnode endpoint of a device.
The function is marked as deprecated in the documentation and is actually
not used anywhere anymore. Drop it and remove the helper function
v4l2_async_nf_fwnode_parse_endpoint() from v4l2-fwnode.c.
This change allows to make the helper function
__v4l2_async_nf_add_connection() visibility private to v4l2-async.c so
that there is no risk drivers can mistakenly use it.

Commit fe8a339783 ("media: mediatek: vcodec: Read HW active status

With a correct Devicetree, that is, one that follows the dt-binding, it
wouldn't be possible to trigger such a buffer overflow. Even so, update
the range validation of the reg property, so that the smatch warning is
fixed and if an incorrect Devicetree is ever supplied the code errors
out instead of causing memory corruption.

The vdec_msg_queue_init() function has a loop which does:
for (i = 0; i < NUM_BUFFER_COUNT; i++) {
Each iteration initializes one element in the msg_queue->lat_buf[] array
and then the clean up function vdec_msg_queue_deinit() frees each
element of the msg_queue->lat_buf[] array. This clean up code relies
on the assumption that every element is either initialized or zeroed.

Commit f100ce3bbd ("media: verisilicon: Fix crash when probing
encoder") removed vpu_fmt from hantro_try_fmt(), since it was
initialized from vpu_dst_fmt, which may not be initialized, when TRY_FMT
is called. It was replaced by fmt, which is found using the pixelformat.
For the encoder, this changed the fmt to contain the raw format instead
of the coded format. The format constraints as of fmt->frmsize are only
valid for the coded format and are 0 for the raw formats. Therefore, the
size of a encoder OUTPUT device is constrained to 0 and the
v4l2-compliance tests for G_FMT, TRY_FMT, and SET_FMT fail.
Bring back vpu_fmt to use the coded format on an encoder OUTPUT device,
but initialize it using the currently set pixelformat on dst_fmt, which
is the coded format on an encoder.

If fwnode_graph_get_remote_endpoint() fails, 'fwnode' is known to be NULL,
so fwnode_handle_put() is a no-op.
Release the reference taken from a previous fwnode_graph_get_port_parent()
call instead.
Also handle fwnode_graph_get_port_parent() failures.
In order to fix these issues, add an error handling path to the function
and the needed gotos.
