These formats are compressed 14-bit raw bayer formats with four different
pixel orders. They are similar to 10-bit variants. The formats added by
this patch are
V4L2_PIX_FMT_SBGGR14P
V4L2_PIX_FMT_SGBRG14P
V4L2_PIX_FMT_SGRBG14P

+14-bit packed Bayer formats
+
+
+Description
+===========
+
+These four pixel formats are packed raw sRGB / Bayer formats with 14
+bits per colour. Every four consecutive samples are packed into seven
+bytes. Each of the first four bytes contain the eight high order bits
+of the pixels, and the three following bytes contains the six least
+significants bits of each pixel, in the same order.
+
+Each n-pixel row contains n/2 green samples and n/2 blue or red samples,
+with alternating green-red and green-blue rows. They are conventionally
+described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
+of one of these formats:
+
+**Byte Order.**
+Each cell is one byte.

The code will be called MEDIA_BUS_FMT_Y10_2X8_PADHI_LE.
It is similar to MEDIA_BUS_FMT_SBGGR10_2X8_PADHI_LE
but MEDIA_BUS_FMT_Y10_2X8_PADHI_LE describes grayscale
data.

The new format will be called V4L2_PIX_FMT_Y10P.
It is similar to the V4L2_PIX_FMT_SBGGR10P family formats
but V4L2_PIX_FMT_Y10P is a grayscale format.

of_graph_get_next_endpoint increases the refcount of the returned
node and decreases the refcount of the passed node. Take this into
account and use of_node_put properly.

Use more logical clock names - similar to the names in documentation.
This will allow better handling of the clocks in the driver when support
for more hardware versions is added - equivalent clocks on different
hardware versions will have the same name.

The CSID decodes the input data stream. When the input comes from
the Test Generator the format of the stream is set on the source
media pad. When the input comes from the CSIPHY the format is the
one on the sink media pad. Use the proper format for each case.

Simplify getting of the line pointer by using the container_of
macro instead of traversing media controller links.

Use "no change" value when clearing CAMIF status and make sure
this is done before configuring the new command.

Add structs with 8x96 resources. As the number of CSIPHY, CSID
and VFE hardware modules is different on 8x16 and 8x96 select
the number at runtime and allocate needed structures
dynamically.

unsigned int?
I guess if there are only such changes then a patch on top of the current
set might be more practical than a new version of the entire set.

There is a PM domain for each of the VFE hardware modules. Add
support for basic runtime PM support to be able to control the
PM domains. When a PM domain needs to be powered on - a device
link is created. When a PM domain needs to be powered off -
its device link is removed. This allows separate and
independent control of the PM domains.
Suspend/Resume is still not supported.

Shouldn't the regulator be enabled in the runtime_resume callback instead?

Ideally - yes, but it becomes more complex (different pipelines are possible
and we have only one callback) so (at least for now) I have left it as it is
and stated in the commit message that suspend/resume is still not supported.

Yes, I'll add it here and on all other places.

I'd really like to say that it cannot fail :) at least the callback is
empty for now and cannot fail, but the logic in pm_runtime_get_sync()
is not that simple and I'm really not sure. I'll add checks in the code
in case it fails.

CSID hardware modules on 8x16 and 8x96 are similar. There is no
need to duplicate the code by adding separate versions. Just
update the register macros to return the correct register
addresses.

ISPIF hardware modules on 8x16 and 8x96 are similar. However on
8x96 the ISPIF routes data to two VFE hardware modules. Add
separate interrupt handler for 8x96 to handle the additional
interrupts.

As the 8x16 and 8x96 support different formats, separate the
arrays which contain the supported formats. For the VFE also
add separate arrays for RDI and PIX subdevices.

Cc: linux-kernel, Todor Tomov
Add support to output UYVY formats from the VFE (via the PIX interface).
A configuration for the realign module in the VFE is added. As the
realign module is present on 8x96 but not on 8x16, this is supported
on 8x96 only.

Usually the format on the source pad is the same as on the sink pad.
However the CSID is able to do some format conversions. To support
this make the format on the source pad selectable amongst a list
of formats. This list can be different for each sink pad format.
This is still not used but will be when the format conversions
are implemented.

Changing a user control value can trigger an event to other
users. Add support for that.

You could merge this to the patch that adds the format definitions. Or:
Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com>
And preferrably move it to earlier in the patchset where new formats are
added.

Unless I am mistaken the only thing we're waiting for is an Ack from Rob for
patch 8 (dt bindings), right?
If I get that this week, then I can make a pull request in time for 4.19.

We are definitely waiting for Rob's feedback. If there are more comments
meanwhile I will take care of them too but I think we don't have any so
far (or at least didn't have any until some minutes ago :)).

This will be really nice if we can do it. Thanks!

When running sparse I get these warnings:
camss/camss-csiphy-2ph-1-0.c:170:28: warning: symbol 'csiphy_ops_2ph_1_0' was not declared. Should it be static?
camss/camss-csiphy-3ph-1-0.c:250:28: warning: symbol 'csiphy_ops_3ph_1_0' was not declared. Should it be static?
camss/camss-vfe-4-1.c:976:25: warning: symbol 'vfe_ops_4_1' was not declared. Should it be static?
camss/camss-vfe-4-7.c:1098:25: warning: symbol 'vfe_ops_4_7' was not declared. Should it be static?
checkpatch.pl complains about this as well.
There are externs in vfe.c, but those should probably be moved to camss-vfe.h.
It should solves both checkpatch and sparse.

Hans

Yes, this is correct. I can fix this in an additional small patch.
