When the source device is operating above 1.5 Gbps per lane, it needs to
send the Skew Calibration Sequence before sending any HS data. If the
DPHY is initialized after the source stream is started, then it might
miss the sequence and not be able to receive data properly. Move the
start of source subdev to the end of the sequence to make sure
everything is ready to receive data before the source starts streaming.

phy_pm_runtime_*() calls return -EOPNOTSUPP and do nothing else if
runtime PM is not enabled. Use that fact to make the code flow a bit
better. Call phy_pm_runtime_put() unconditionally since it will simply
return an error if runtime PM is not enabled. The variable got_pm is not
longer needed.
This also fixes a bug where phy_pm_runtime_get_sync() returning a
positive value (in case device usage count is > 0) would be treated as
an error.

An ATR is a device that looks similar to an i2c-mux: it has an I2C
slave "upstream" port and N master "downstream" ports, and forwards
transactions from upstream to the appropriate downstream port. But is
is different in that the forwarded transaction has a different slave
address. The address used on the upstream bus is called the "alias"
and is (potentially) different from the physical slave address of the
downstream chip.
Add a helper file (just like i2c-mux.c for a mux or switch) to allow
implementing ATR features in a device driver. The helper takes care or
adapter creation/destruction and translates addresses at each transaction.

An adapter might need to know when a new device is about to be
added. This will soon bee needed to implement an "I2C address
translator" (ATR for short), a device that propagates I2C transactions
with a different slave address (an "alias" address). An ATR driver
needs to know when a slave is being added to find a suitable alias and
program the device translation map.
Add an attach/detach callback pair to allow adapter drivers to be
notified of clients being added and removed.

The pipeline validation being done here is completely broken. Firstly,
it assumes that the media_graph_walk_* APIs perform a depth-first
traversal on the media graph. They claim to do so, but that is not the
case in reality. The order of traversal seems to not be guaranteed, just
that all the entities in the graph will be traversed at some point. This
means that the device that last touched for format can't be reliably
found.
Secondly, a driver is not supposed to validate format propagation
through the entire pipeline anyway. It should just mind its own formats
and its own links, and should not traverse the graph to validate the
entire thing.
Due to these two reasons, it is better to just drop the validation.

Each CSI2 stream can be multiplexed into 4 independent streams, each
identified by its virtual channel number. To capture this multiplexed
stream, the application needs to tell the driver how it wants to route
the data. It needs to specify which context should process which stream.
This is done via the new routing APIs.
Add ioctls to accept routing information from the application and save
that in the driver. This can be used when starting streaming on a
context to determine which route and consequently which virtual channel
it should process.

Use get_frame_desc() to get the frame desc from the connected source,
and use the provided virtual channel instead of hardcoded one.
get_frame_desc() works per stream, but as we don't support multiple
streams yet, we will just always use stream 0. If the source doesn't
support get_frame_desc(), fall back to the previous method of always
capturing virtual channel 0.

Add routing and stream_config support to CAL driver.
Add multiplexed streams support. CAL has 8 dma-engines and can capture 8
separate streams at the same time.
Add 8 video device nodes, each representing a single dma-engine, and set
the number of source pads on camerarx to 8. Each video node can be
connected to any of the source pads on either of the camerarx instances
using media links. Camerarx internal routing is used to route the
incoming CSI-2 streams to one of the 8 source pads.

CAL HW interrupts are inherently racy. If we get both start and end
interrupts, we don't know what has happened: did the DMA for a single
frame start and end, or did one frame end and a new frame start?
Usually for normal pixel frames we get the interrupts separately. If
we do get both, we have to guess. The assumption in the code is that the
active vertical area is larger than the blanking vertical area, and thus
it is more likely that we get the end of the old frame and the start of
a new frame.
However, for embedded data, which is only a few lines high, we always
get both interrupts. Here the assumption is that we get both for the
same frame.

Instead of handling the WDMA START and END interrupts separately, we
need to handle both at the same time to better manage the inherent race
conditions related to CAL interrupts.
Change the code so that we have a single function,
cal_irq_handle_wdma(), which gets two booleans, start and end, as
parameters, which allows us to manage the race conditions in following
patches.

The userspace needs a way to match received metadata buffers to pixel
data buffers. The obvious way to do this is to use the CSI-2 frame
number, as both the metadata and the pixel data have the same frame
number as they come from the same frame.
However, we don't have means to convey the frame number to userspace. We
do have the 'sequence' field, which with a few tricks can be used for
this purpose.
To achieve this, track the frame number for each virtual channel and
increase the sequence for each virtual channel by frame-number -
previous-frame-number, also taking into account the eventual wrap of the
CSI-2 frame number.
This way we get a monotonically increasing sequence number which is
common to all streams using the same virtual channel.
