4e228c365d media: ipu3-cio2: Replace deprecated PCI functions
pcim_iomap_table() and pcim_iomap_regions() have been deprecated.

Replace them with pcim_iomap_region(), and pass the actual driver name
to that function.

9396770c3a media: rcar-csi2: Remove hack to detect NTSC content
In an effort to emulate support for SEQ_{TB,BT} in the R-Car VIN driver
on data captured from a CVBS input a hack was added to detect NTSC vs
PAL. This is ugly and as support for emulated SEQ_{TB,BT} have been
removed from the VIN driver remove the ugly hack.

c1eefe88c3 media: rcar-vin: Simplify the shutdown process
When shutting down capture extra care was needed to try and complete a
buffer that was involved in the emulated support for SEQ_{TB,BT}. This
was needed as a buffer might be queued once to the driver, but two times
to the hardware using different offsets.

As support for SEQ_{TB,BT} is now removed this shutdown process can be
greatly simplified. And in addition the state keeping of the VIN device
can be reduced to a single boolean value instead of keeping track of
this SEQ_{TB,BT} stopping dance.

25482a986e media: rcar-vin: Remove superfluous starting state
The STARTING state is superfluous and can be replaced with a check of
the sequence counter. The design idea is that the first buffer returned
from the driver have to come from the first hardware buffer slot.
Failing this the first 3 buffers queued to the device can be returned
out-of-order.

But it's much clearer to check the sequence counter to only return the
first buffer if it comes from hardware slot 0 then it is to carry around
an extra state just for this. Remove the unneeded state and replace it
with a simpler check.

1dadd89b58 media: rcar-vin: Remove superfluous suspended state
The VIN state of suspended is superfluous. The logic was that when the
device were suspended and in a RUNNING state the state was set to
SUSPENDED. And when resuming it checked if the state is SUSPENDED and if
so started the device and changed it to RUNNING.

This can be avoided by simply checking if the device is in a RUNNING
state at both suspend and resume callbacks. Remove the unneeded
complexity.

f2f0cd8925 media: rcar-vin: Remove emulated SEQ_{TB,BT}
When the driver was converted from soc_camera software support for
V4L2_FIELD_SEQ_TB and V4L2_FIELD_SEQ_BT were added. This was done by
capturing twice to the same VB2 buffer, but at different offsets.

This turned out to be a bad idea and it never really worked properly in
all situations. As the hardware can't support this mode natively remove
trying to emulate it in software. It's still possible to capture TOP or
BOTTOM fields separately or both ALTERNATING. If user-space wants the
same  fields in the same buffer the same hack to capture twice to the
same buffer can be done.

Removing this error prone emulated support pave ways in future work to
simplify the internal buffer handling and making it less fragile, while
enabling adding support for other features the hardware actually
supports.

c57e372b7b media: ti: cal: Add streams support
Add multiplexed streams support. CAL has 8 DMA-engines and can capture 8
separate streams at the same time. The driver filters the streams based
on CSI-2 virtual channel number and datatype. CAL may have (depending on
the SoC) two CSI-2 RX blocks, which share the 8 DMA-engines, so the
number of capturable streams does not change even if there are two CSI-2
RX blocks.

Add 8 video device nodes, each representing a single DMA-engine, and set
the number of source pads on CSI-2 RX blocks to 8. Each video node can be
connected to any of the source pads on either of the CSI-2 RX instances
using media links. CSI-2 RX block's subdevice internal routing is used
to route the incoming CSI-2 streams to one of the 8 source pads.

Only video data streams are supported at the moment.

When v4l2_subdev_init_finalize() fails no changes have been made to

Instead this should be done from the probe_error_v4l2_subdev_cleanup

the v4l2_subdev_cleanup() call to have the reverse call order of probe().

e2a3b695bc media: i2c: ds90ub960: Configure serializer using back-channel
For DS90UB9702-Q1, it is recommended to configure some serializer
settings over the back-channel before the forward-channel is active.

This can only be done if the serializer's I2C address on the FPD-Link
bus is populated in the device tree node.

Move UB953 register defines to a header file. This is done so that the
deserializer driver can access the defines, and do some early
serializer configuration.

ca26126a6c media: dt-bindings: ti,ds90ub960: Allow setting serializer address
The serializer's I2C address on the FPD-Link bus is usually communicated
to the deserializer once the forward-channel is established. But in some
cases it might be necessary to program the serializer (over the
back-channel) before the forward-channel is established.

This can be used e.g. to correct serializer configuration which
otherwise would prevent the FC to be enabled. To be able to communicate
to the serializer before the forward-channel is up, the deserializer
driver neds to know the default i2c address of the serializer.

Allow setting the serializer i2c address using the 'reg' property. This
is optional, and usually not needed.

We also move ub960_reset() so that it is accessible from
ub960_init_rx_ports().

2ca499384e media: i2c: ds90ub960: Add RX port iteration support
The driver does a lot of iteration over the RX ports with for loops. In
most cases the driver will skip unused RX ports. Also, in the future
patches the FPD-Link IV support will be refreshed with TI's latest init
sequences which involves a lot of additional iterations over the RX
ports, often only for FPD-Link IV ports.

To make the iteration simpler and to make it clearer what we're
iterating over (all or only-active, all or only-fpd4), add macros and
support functions for iterating the RX ports. Use the macros in the
driver, replacing the for loops.

ways and have a lot of identical registers, there are also plenty of

To clarify the situation a bit, move the UB9702 registers to a separate
