We will soon need to return more than a boolean completion status from
the vsp1_dlm_irq_frame_end() IRQ handler. Turn the return value into a
bitfield to prepare for that. No functional change is introduced here.

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.

The DRM pipeline handling code uses the entity's pipe list head to check
whether the entity is already included in a pipeline. This method is a
bit fragile in the sense that it uses list_empty() on a list_head that
is a list member. Replace it by a simpler check for the entity pipe
pointer.

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While at it remove the outdated comment that states that entities are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.

Depending on the chosen standard, configure the decoder to use the
appropriate color encoding standard (PAL-like, NTSC-like or SECAM).
Until now, the decoder was not configured for a specific color standard,
making it autodetect the color encoding.
While this may sound fine, it potentially causes the wrong image tuning
parameters to be applied (e.g. tuning parameters for NTSC are applied to
a PAL source), and may confuse users about what the actual standard is
in use.
This commit explicitly configures the color standard the decoder will
use, making it visually obvious if a wrong standard was chosen.

The user-supplied norm value gets overwritten by the generic .norm
member from the norm_params. That way, we lose the specific norm the
user may want to set.
For instance, if the user specifies V4L2_STD_PAL_60, the value actually
used will be V4L2_STD_525_60, which in the end will be as if the user
had specified V4L2_STD_NTSC, since this is always the first bitfield we
match the norm value against before configuring the hardware.
The norm_params array is only there to match a norm with an output
resolution. The norm value itself should not be changed.

All sound drivers that don't depend on PNP can be safelly
build with COMPILE_TEST, as ISA provides function stubs to
be used for such purposes.
As a side effect, with this change, the radio-miropcm20
can now be built outside i386 with COMPILE_TEST.
It should be noticed that ISAPNP currently depends on ISA.
So, on drivers that depend on it, we need to add an

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.

The parsing and registering CSI-2 subdevices with the v4l2 async
framework is a collaborative effort shared between the VIN instances
which are part of the group. When the last VIN in the group is probed it
asks all other VINs to parse its share of OF and record the async
subdevices it finds in the notifier belonging to the last probed VIN.
Once all CSI-2 subdevices in this notifier are bound proceed to register
all VIN video devices of the group and crate media device links between
all CSI-2 and VIN entities according to the SoC specific routing
configuration.

On Gen3 the CSI-2 routing is controlled by the VnCSI_IFMD register. One
feature of this register is that it's only present in the VIN0 and VIN4
instances. The register in VIN0 controls the routing for VIN0-3 and the
register in VIN4 controls routing for VIN4-7.
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
the new routing will still be in effect.

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
