Laurent Pinchart bc3c9c8802 media: v4l: vsp1: Add per-display list internal completion notification support
Display list completion is already reported to the frame end handler,
but that mechanism is global to all display lists. In order to implement
BRU and BRS reassignment in DRM pipelines we will need to commit a
display list and wait for its completion internally, without reporting
it to the DRM driver. Extend the display list API to support such an
internal use of the display list.

Laurent Pinchart b76b3ce55f media: v4l: vsp1: Replace manual DRM pipeline input setup in vsp1_du_setup_lif
The vsp1_du_setup_lif() function sets up the DRM pipeline input
manually. This duplicates the code from the
vsp1_du_pipeline_setup_inputs() function. Replace the manual
implementation by a call to the function.

As the pipeline has no enabled input in vsp1_du_setup_lif(), the
vsp1_du_pipeline_setup_inputs() function will not setup any RPF, and
will thus not setup formats on the BRU sink pads. This isn't a problem
as all inputs are disabled, and the BRU sink pads will be reconfigured
from the atomic commit handler when inputs will be enabled.

Laurent Pinchart 9fd099b183 media: v4l: vsp1: Don't start/stop media pipeline for DRM
The DRM support code manages a pipeline of VSP entities, each backed by
a media entity. When starting or stopping the pipeline, it starts and
stops the media pipeline through the media API in order to store the
pipeline pointer in every entity.

The driver doesn't use the pipe pointer in media entities, neither does
it rely on the other effects of the media_pipeline_start() and
media_pipeline_stop() functions. Furthermore, as the media links for the
DRM pipeline are never set up correctly, and as the pipeline can be
modified dynamically when enabling or disabling planes, the current
implementation is not correct. Remove the incorrect and unneeded code.

While at it remove the outdated comment that states that entities are
not started when the LIF is setup, as they now are.

Niklas Söderlund c0cc5aef31 media: rcar-vin: add link notify for Gen3
Add the ability to process media device link change requests. Link
enabling is a bit complicated on Gen3, whether or not it's possible to
enable a link depends on what other links already are enabled. On Gen3
the 8 VINs are split into two subgroup's (VIN0-3 and VIN4-7) and from a
routing perspective these two groups are independent of each other.
Each subgroup's routing is controlled by the subgroup VIN master
instance (VIN0 and VIN4).

There are a limited number of possible route setups available for each
subgroup and the configuration of each setup is dictated by the
hardware. On H3 for example there are 6 possible route setups for each
subgroup to choose from.

This leads to the media device link notification code being rather large
since it will find the best routing configuration to try and accommodate
as many links as possible. When it's not possible to enable a new link
due to hardware constrains the link_notifier callback will return
-EMLINK.

feature of this register is that it's only present in the VIN0 and VIN4

To be able to control routing from a media device this function is need
to control runtime PM for the subgroup master (VIN0 and VIN4). The
subgroup master must be switched on before the register is manipulated,
once the operation is complete it's safe to switch the master off and

Niklas Söderlund 6c51f646f6 media: rcar-vin: fix handling of single field frames (top, bottom and alternate fields)
There was never proper support in the VIN driver to deliver ALTERNATING
field format to user-space, remove this field option. The problem is
that ALTERNATING field order requires the sequence numbers of buffers
returned to userspace to reflect if fields were dropped or not,
something which is not possible with the VIN drivers capture logic.

The VIN driver can still capture from a video source which delivers
frames in ALTERNATING field order, but needs to combine them using the
VIN hardware into INTERLACED field order. Before this change if a source
was delivering fields using ALTERNATE the driver would default to
combining them using this hardware feature. Only if the user explicitly
requested ALTERNATE field order would incorrect frames be delivered.

The height should not be cut in half for the format for TOP or BOTTOM
fields settings. This was a mistake and it was made visible by the
scaling refactoring. Correct behavior is that the user should request a
frame size that fits the half height frame reflected in the field
setting. If not the VIN will do its best to scale the top or bottom to
the requested format and cropping and scaling do not work as expected.

Niklas Söderlund 2db44b3dac media: rcar-vin: set a default field to fallback on
If the field is not supported by the driver it should not try to keep
the current field. Instead it should set it to a default fallback. Since
trying a format should always result in the same state regardless of the
current state of the device.

Niklas Söderlund d1dc6bacef media: rcar-vin: all Gen2 boards can scale simplify logic
The logic to preserve the requested format width and height are too
complex and come from a premature optimization for Gen3. All Gen2 SoC
can scale and the Gen3 implementation will not use these functions at
all so simply preserve the width and height when interacting with the
subdevice much like the field is preserved simplifies the logic quite a
bit.

When Gen3 support is added to the driver more than model ID will be
different for the different SoCs. To avoid a lot of if statements in the
code create a struct rvin_info to store this information.

While we are at it rename the poorly chosen enum which contains the
different model IDs from chip_id to model_id. Also sort the compatible
string entries and make use of of_device_get_match_data() which will
always work as the driver is DT only, so there's always a valid match.

Niklas Söderlund 23525ef9f8 media: rcar-vin: move subdevice handling to async callbacks
In preparation for Gen3 support move the subdevice initialization and
clean up from rvin_v4l2_{register,unregister}() directly to the async
callbacks. This simplifies the addition of Gen3 support as the
rvin_v4l2_register() can be shared for both Gen2 and Gen3 while direct
subdevice control are only used on Gen2.

While moving this code drop a large comment which is copied from the
framework documentation and fold rvin_mbus_supported() into its only
caller. Also move the initialization and cleanup code to separate
functions to increase readability.

Mauro Carvalho Chehab 99ed3dd83f media: isppreview: fix __user annotations
The 'from' variable at preview_config() expects an __user * type.

However, the logic there does:

    from = *(void * __user *) ((void *)cfg + attr->config_offset);

With actually means a void pointer, pointing to a void __ user
pointer. When the first pointer is de-referenced with *(foo),
the type it returns is "void *" instead of "void __user *".

Change it to:
    from = *(void __user **) ((void *)cfg + attr->config_offset);

in order to obtain, when de-referenced, a void __user pointer,
as desired.

That prevent those warnings:

if v4l2_subdev_call(..., VENC_GET_FLD,...) fails, it
currently returns a random value. Instead, return 1.

That's probably better than returning 0, as this is very
likely what happens in practice with the current code, as
as the probably of an unititialized 32 bits integer to
have an specific value (0, in this case), is 1/(2^32).

An alternative would be to return an error code, and
let the caller to hint, based on the past received
frame, but that sounds weird.

Kieran Bingham 639fa43d59 media: vsp1: Fix BRx conditional path in WPF
When a BRx is provided by a pipeline, the WPF must determine the master
layer. Currently the condition to check this identifies pipe->bru ||
pipe->num_inputs > 1.

The code then moves on to dereference pipe->bru, thus the check fails
static analysers on the possibility that pipe->num_inputs could be
greater than 1 without pipe->bru being set.

The reality is that the pipeline must have a BRx to support more than
one input, thus this could never cause a fault - however it also
identifies that the num_inputs > 1 check is redundant.

Remove the redundant check - and always configure the master layer
appropriately when we have a BRx configured in our pipeline.

Alexandre Courbot 82e071e254 media: venus: vdec: fix format enumeration
find_format_by_index() stops enumerating formats as soon as the index
matches, and returns NULL if venus_helper_check_codec() finds out that
the format is not supported. This prevents formats to be properly
enumerated if a non-supported format is present, as the enumeration will
end with it.

Fix this by moving the call to venus_helper_check_codec() into the loop,
and keep enumerating when it fails.

Linus Torvalds f5a8eb632b arch: remove obsolete architecture ports
This removes the entire architecture code for blackfin, cris, frv, m32r,
 metag, mn10300, score, and tile, including the associated device drivers.
 
 I have been working with the (former) maintainers for each one to ensure
 that my interpretation was right and the code is definitely unused in
 mainline kernels. Many had fond memories of working on the respective
 ports to start with and getting them included in upstream, but also saw
 no point in keeping the port alive without any users.
 
 In the end, it seems that while the eight architectures are extremely
 different, they all suffered the same fate: There was one company
 in charge of an SoC line, a CPU microarchitecture and a software
 ecosystem, which was more costly than licensing newer off-the-shelf

Merge tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pul removal of obsolete architecture ports from Arnd Bergmann:
 "This removes the entire architecture code for blackfin, cris, frv,
  m32r, metag, mn10300, score, and tile, including the associated device
  drivers.

  I have been working with the (former) maintainers for each one to
  ensure that my interpretation was right and the code is definitely
  unused in mainline kernels. Many had fond memories of working on the
  respective ports to start with and getting them included in upstream,
  but also saw no point in keeping the port alive without any users.

  In the end, it seems that while the eight architectures are extremely
  different, they all suffered the same fate: There was one company in
  charge of an SoC line, a CPU microarchitecture and a software
  ecosystem, which was more costly than licensing newer off-the-shelf
  CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
  seems that all the SoC product lines are still around, but have not
  used the custom CPU architectures for several years at this point. In
  contrast, CPU instruction sets that remain popular and have actively
  maintained kernel ports tend to all be used across multiple licensees.

  [ See the new nds32 port merged in the previous commit for the next
    generation of "one company in charge of an SoC line, a CPU
    microarchitecture and a software ecosystem"   - Linus ]

Hans Verkuil 6ec1cbf6b1 media: cec: improve CEC pin event handling
It turns out that the struct cec_fh event buffer size of 64 events
(64 for CEC_EVENT_PIN_CEC_LOW and 64 for _HIGH) is too small. It's
about 160 ms worth of events and if the Raspberry Pi is busy, then it
might take too long for the application to be scheduled so that it can
drain the pending events. Increase these buffers to 800 events which
is at least 2 seconds worth of events.

There is also a FIFO in between the interrupt and the cec-pin thread.
The thread passes the events on to the CEC core. It is important that
should this FIFO fill up the cec core will be informed that events
have been lost so this can be communicated to the user by setting
CEC_EVENT_FL_DROPPED_EVENTS.

It is very hard to debug CEC problems if events were lost without
informing the user of that fact.

If events were dropped due to the FIFO filling up, then the debugfs
status file will let you know how many events were dropped.

Niklas Söderlund dc9aec795f media: rcar-vin: use scratch buffer and always run in continuous mode
Instead of switching capture mode depending on how many buffers are
available use a scratch buffer and always run in continuous mode. By
using a scratch buffer the responsiveness of the capture loop is
increased as it can keep running even if there are no buffers available
from userspace.

As soon as a userspace queues a buffer it is inserted into the capture
loop and returned as soon as it is filled. This is a improvement on the
previous logic where the whole capture loop was stopped and switched to
single capture mode if userspace did not feed the VIN driver buffers at
the same time it consumed them. To make matters worse it was difficult
for the driver to reenter continuous mode if it entered single mode even
if userspace started to queue buffers faster. This resulted in
suboptimal performance where if userspace where delayed for a short
period the ongoing capture would be slowed down and run in single mode
until the capturing process where restarted.

An additional effect of this change is that the capture logic can be
made much simple as we know that continuous mode will always be used.

fallback on single capture mode if userspace can't queue buffers as fast
as the VIN driver consumes them.
