[PATCH v3 0/9] TVP5150 fixes and new features

[Marco Felsch]

Hi,

this is my v3 with the integrated reviews from my v2 [1]. This serie
applies to Mauro's experimental.git [2].

@Mauro:
Patch ("media: tvp5150: fix irq_request error path during probe") is new
in this series. Maybe you can squash them with ("media: tvp5150: Add sync lock
interrupt handling"), thanks.

I've tested this series on a customer dt-based board. Unfortunately I
haven't a device which use the em28xx driver. So other tester a welcome :)

[PATCH v3 1/9] partial revert of "[media] tvp5150: add HW input connectors support"

[Marco Felsch]

From: Javier Martinez Canillas <javierm@redhat.com>

Commit f7b4b54e6364 ("[media] tvp5150: add HW input connectors support")
added input signals support for the tvp5150, but the approach was found
to be incorrect so the corresponding DT binding commit 82c2ffeb217a
("[media] tvp5150: document input connectors DT bindings") was reverted.

This left the driver with an undocumented (and wrong) DT parsing logic,
so lets get rid of this code as well until the input connectors support
is implemented properly.

It's a partial revert due other patches added on top of mentioned commit
not allowing the commit to be reverted cleanly anymore. But all the code
related to the DT parsing logic and input entities creation are removed.

[PATCH v3 2/9] media: tvp5150: fix irq_request error path during probe

[Marco Felsch]

Commit 37c65802e76a ("media: tvp5150: Add sync lock interrupt handling")
introduced the interrupt handling. But we have to free the
v4l2_ctrl_handler before we can return the error code.

[PATCH v3 3/9] media: tvp5150: add input source selection of_graph support

[Marco Felsch]

This patch adds the of_graph support to describe the tvp connections.
Physical the TVP5150 has three ports: AIP1A, AIP1B and YOUT. As result
of discussion [1],[2] the device-tree maps these ports 1:1. The svideo
connector must be conneted to port@0/endpoint@1, look at the Documentation
for more information. Since the TVP5150 is a converter the device-tree
must contain at least 1-input and 1-output port. The mc-connectors and
mc-links are only created if the device-tree contains the corresponding
connector nodes. If more than one connector is available the
media_entity_operations.link_setup() callback ensures that only one
connector is active.

Changelog:

v3:
- probe(): s/err/err_free_v4l2_ctrls
- drop MC dependency for tvp5150_pads

v2:
- adapt commit message
- unify ifdef switches
- rename tvp5150_valid_input -> tvp5150_of_valid_input, to be more precise
- mc: use 2-input and 1-output pad
- mc: link svideo connector to both input pads
- mc: enable/disable svideo links in one go
- mc: change link_setup() behaviour, switch the input src don't require a
      explicite disable before.
- mc: rename 'local' media_pad param to tvp5150_pad to avoid confusion
- mc: enable link to the first available connector and set the
      corresponding tvp5150 input src per default during registered()
- mc/of: factor out oftree connector allocation
- of: drop svideo dt port
- of: move svideo connector to port@0/endpoint@1
- of: require at least 1-in and 1-out endpoint

[PATCH v3 4/9] media: dt-bindings: tvp5150: Add input port connectors DT bindings

[Marco Felsch]

The TVP5150/1 decoders support different video input sources to their
AIP1A/B pins.

Possible configurations are as follows:
  - Analog Composite signal connected to AIP1A.
  - Analog Composite signal connected to AIP1B.
  - Analog S-Video Y (luminance) and C (chrominance)
    signals connected to AIP1A and AIP1B respectively.

This patch extends the device tree bindings documentation to describe
how the input connectors for these devices should be defined in a DT.

Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>

Changelog:

v3:
- remove examples for one and two inputs
- replace space by tabs

v2:
- adapt port layout in accordance with
  https://www.spinics.net/lists/linux-media/msg138546.html with the
  svideo-connector deviation (use only one endpoint)

[PATCH v3 5/9] media: v4l2-subdev: add stubs for v4l2_subdev_get_try_*

[Marco Felsch]

In case of missing CONFIG_VIDEO_V4L2_SUBDEV_API those helpers aren't
available. So each driver have to add ifdefs around those helpers or
add the CONFIG_VIDEO_V4L2_SUBDEV_API as dependcy.

Make these helpers available in case of CONFIG_VIDEO_V4L2_SUBDEV_API
isn't set to avoid ifdefs. This approach is less error prone too.

[PATCH v3 6/9] media: v4l2-subdev: fix v4l2_subdev_get_try_* dependency

[Marco Felsch]

These helpers make us of the media-controller entity which is only
available if the CONFIG_MEDIA_CONTROLLER is enabled.

Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>

Changelog:

v3:
- add CONFIG_MEDIA_CONTROLLER switch instead of moving the
  v4l2_subdev_get_try_* APIs into the existing one.

v2:

VIDEO_V4L2_SUBDEV_API (used below) depends on MEDIA_CONTROLLER. Either this
or the previous patch would be meaningful but not both.

Considering a driver wouldn't use the functions below if it did not need or
could use VIDEO_V4L2_SUBDEV_API, I'd suggest retaining the other patch.

Oh sorry didn't checked the Kconfig.
Mauro can you drop that patch and use only the patch ("media: v4l2-subdev:
add stubs for v4l2_subdev_get_try_*")?

[PATCH v3 7/9] media: tvp5150: add FORMAT_TRY support for get/set selection handlers

[Marco Felsch]

Since commit 10d5509c8d50 ("[media] v4l2: remove g/s_crop from video ops")
the 'which' field for set/get_selection must be FORMAT_ACTIVE. There is
no way to try different selections. The patch adds a helper function to
select the correct selection memory space (sub-device file handle or
driver state) which will be set/returned.

The TVP5150 AVID will be updated if the 'which' field is FORMAT_ACTIVE
and the requested selection rectangle differs from the already set one.

[PATCH v3 8/9] media: tvp5150: initialize subdev before parsing device tree

[Marco Felsch]

From: Michael Tretter <m.tretter@pengutronix.de>

There are several debug prints in the tvp5150_parse_dt() function, which
do not print the prefix, because the v4l2_subdev is not initialized, yet.

Initialize the v4l2_subdev before parsing the device tree to fix the
debug messages.

[PATCH v3 9/9] media: tvp5150: add s_power callback

[Marco Felsch]

Don't en-/disable the interrupts during s_stream because someone can
disable the stream but wants to get informed if the stream is locked
again. So keep the interrupts enabled the whole time the pipeline is
opened.

Hi Mauro,

I don't want to spam you. Can you give me some feedback? I know the
merge window is a busy time, so maybe you have some time now.

Regards,
Marco

Sorry for taking so long on looking into it... has been really busy
those days :-(

I applied patch 2/9. Patch 3 doesn't apply. Would you mind
rebasing it on the top of upstream? there are some non-trivial
conflicts (perhaps I just missed some other preparation patch?).

I suspect that it would be easier if you could rebase your tree
on the top of the latest upstream one, e. g.:

	git://linuxtv.org/media_tree.git
	
(master branch)

Mauro
