This series adds Tegra210 VI and CSI driver for built-in test pattern
generator (TPG) capture.

Tegra210 supports max 6 channels on VI and 6 ports on CSI where each
CSI port is one-to-one mapped to VI channel for video capture.

This series has TPG support only where it creates hard media links
between CSI subdevice and VI video device without device graphs.

v4l2-compliance results are available below the patch diff.

[v0]:	Includes,
	- Adds CSI TPG clock to Tegra210 clock driver
	- Host1x video driver with VI and CSI clients.
	- Support for Tegra210 only.
	- VI CSI TPG support with hard media links in driver.
	- Video formats supported by Tegra210 VI
	- CSI TPG supported video formats


Sowjanya Komatineni (5):
  dt-bindings: clock: tegra: Add clk id for CSI TPG clock
  clk: tegra: Add Tegra210 CSI TPG clock gate
  dt-binding: tegra: Add VI and CSI bindings
  media: tegra: Add Tegra Video input driver for Tegra210
  arm64: tegra: Add Tegra VI CSI suppport in device tree

I'm trying to compile this patch series using the media_tree master

And indeed, struct host1x_client as defined in include/linux/host1x.h doesn't
have a 'host' field.

Does this series depend on another patch that's not yet in mainline?

Sowjanya's been working on top of linux-next, so, yes, this patch
depends on a change that's been merged into the DRM tree for v5.6-rc1.

I noticed the warning in queue_setup and will be removed in v2.

But errors are related to not using latest host1x driver. latest host1x 
driver changed parent member to host.

So vi/csi driver also uses new member name host. Probably media_tree 
don't have latest host1x driver

Is there a specific linux-next tag that works? I tried next-20200131 but that
failed to boot. Same problem with the mainline repo since the host1x patches
were merged yesterday. It compiles fine, but the boot just stops. Or am I
missing some kernel config that is now important to have?

linux-next and mainline are currently regressing on Tegra210 (and some
Tegra124) boards. I just sent out a series that fixes the regression for
me:

	http://patchwork.ozlabs.org/project/linux-tegra/list/?series=156215

Please test if this works for you. If so, I'll send this to Dave as soon
as possible.

I'll try it on Tuesday as I don't have access to the Jetson TX1 until then. It
looks promising since I think that the last message I saw was a PM message.

Great. My local testing on Jetson Nano confirms that this fixes boot on
top of linux-next and I've also run it through our internal test farm
with success. I'll push this to my drm/tegra/for-next branch, so it
should show up in linux-next on Monday.

Thank you, now it boots on mainline + this series + the new VI/CSI driver.

Since this driver creates a /dev/media0 device you should test with:

v4l2-compliance -m0 -s10: that tests everything found in the media topology.

It finds a few issues in the media topology itself:

----------------------------------------------------------------------------
$ v4l2-compliance -M0
v4l2-compliance SHA: 5af0730d06247a2de487abf2e00e70b156f1fb82, 64 bits, 64-bit time_t

Compliance test for host1x_video device /dev/media0:

Note: the -M0 option tests just /dev/media0 without testing any of the devices
mentioned in the topology. Use -m0 for that.

I see a lot of spam in the kernel log:

[  484.362145] tegra-vi 54080000.vi: TPG mode is set to Black/White Direct Mode
[  486.147937] tegra-csi 54080838.csi: using Tegra default WIDTH X HEIGHT (1920x1080)
[  486.155499] tegra-csi 54080838.csi: using Tegra default RAW10 video format
[  486.162403] tegra-csi 54080838.csi: using Tegra default RAW10 video format

Change that to dev_dbg or delete altogether.

I also noticed that changing the test pattern while streaming did not seem to have
any effect until I stop and restart streaming. Is that a limitation of the HW or of
the driver?

Note that the RGB pixelformat appears to be incorrect: it is set to RGB32 but it
should be BGR32. Actually, it should be XBGR32 since there is no alpha channel
present (I think). RGB32 and BGR32 are deprecated in favor of RGBX/A and X/ABGR.

ok, removed TPG mode message in v2.

Other above messages are to log using default format when requested 
format is not supported by TPG mode.

Will change them to dev_dbg.

Do you mean changing test pattern mode of different channel while other 
channels are streaming?

In v1, pg mode from handler is stored in vi which is common for all 
channels.

So, v2 has change to use channel specific pg mode rather than common 
mode for all channels.

No, from the same channel. E.g. v4l2-ctl --stream-mmap, then do from another
console 'v4l2-ctl -c test-pattern=1'.

It depends on the hardware whether or not you can change the test pattern
while streaming. But it is nice for testing if this is possible.

That sounds better. You want independent test patterns for each channel
if possible.

Test-pattern mode changes during active streaming will not get set as 
test-pattern mode is in CSI and mode is set every time during the start 
of streaming and then VI keeps capturing the frames.

basically its during CSI subdevice stream enable.
