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.

[v8]:	Includes,
	- minor change to use device managed allocation fo vi and csi for now.
	  May need to change back to non device managed allocation later when
	  support for direct host1x client driver unbind and bind is added.

[v7]:	Includes,
	- v6 feedback
	- moved registering v4l2 nodes and creating tpg media links to happen
	  after both host1x client inits so during direct host1x client driver
	  unbind and bind order of client unregister/register will not impact.
	- All channels resources and freeing happens during v4l2 device release
	  callback.
	- module unload/load works with below host1x bus driver fix.
	  http://patchwork.ozlabs.org/patch/1268191/

[v6]:	Includes,
	- v5 feedback
	- fix for csi_tpg clock parent
	- fix to free channel resources in video device release callback
	  for registered video devices as resource might still be in use
	  when application holds handle to it during driver unbind.
	- added blanking intervals based on resolution and bpp for csi
	  internal tpg.
	- added implementation for subdev pad ops enum_frame_size and
	  enum_frame_interval.

[v5]:	Includes,
	- v4 feedback
	- fix for venc powergate mc reset order.
	- fix to have unbind and bind work during v4l2-ctl sleep and streaming.

[v4]:	Includes,
	- v3 feedback changes and some improvements
	- Fixes tegra_channel_buffer struct to use v4l2 buffer as first
	  member. This also fixes crash of unable to handle kernel write
	  to read-only memory.
	- Uses separate host1x sync ids for frame start and memory write
	  ack as single sync id for both can cause sync loss between exact
	  frame start and memory write ack events.
	- Uses client managed host1x syncpoints.
	- Includes fix to increment syncpoint counter to match cached value
	  to synchronize in case of timeouts or missed hardware triggers.
	- Frame start and memory write ack syncpoint FIFO's are of size 2.
	  So, updated capture logic to avoid adding more than 2 sync point
	  condition requests to FIFOs to avoid overflow.
	- Implemented PM ops for runtime suspend and resume along with generic
	  power domains to allow proper power gate and ungate sequencing along
	  with MC VI flush during power gate.
	- Fixed Tegra210 device tree sor power domain clocks.
	- Added missing reset-cells to mc node.

[v3]:	Includes,
	- video device node handling set/get formats of all devices
	  in the pipeline.
	- Removed subdev nodes.
	- Fixed frame sync timeout issue due to CSI clocks not properly
	  set for corresponding blocks.
	- uses minimum 3 buffers to be queued to fixed memory race between
	  DMA writes and userspace reads causing kernel hang reporting
	  kernel write to read-only memory.
	- Improved capture threads and done threads to avoid possible
	  race conditions and added recovery in case of frame sync timeout.
	- Passes all the V4L compliance tests.

[v2]:	Includes,
	- v0 feedback
	- Merged files to have Tegra specific separately
	- Moved CSI device as child to VI as Tegra210 CSI is
	  part of VI sharing same host interface and register
	  space.
	- Added link_validate for format validation.
	- Fixes for passing v4l2-compliance for media, video,
	  and subdevices.

[v1]:	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

You could also pick up patch 5 because it adds the bindings that are
implemented by the driver in patch 6. But I can also pick that up into
the Tegra tree. In fact, I do have a set of patches to convert some
Tegra bindings to the new json-schema format and the host1x file is
among them. If I do get around to finish those up for v5.8 it might be
better for me to pick up patch 5 so that I can base my conversion patch
on top of that.

Either way is fine with me, so I've acked the three patches. Take which
ones you want and I'll pick up the rest.

Thanks again for your guidance on this patch set!

Hi Hans,

Would like to add a small fix to the driver for explicit check for vi 
and csi availability before TPG setup and cleanup in case if video 
driver is enabled without device tree support where vi and csi drivers 
does not register.

Although we are not enabling driver by default now, would be good to 
have this in this series itself.

Will send out the updated version, please pick v9.

Thanks

Sowjanya

Sorry Hans. Just sent v9 which has small fix of explicit check on csi 
and vi both channels availability before TPG setup and cleanup.

As for later Tegras (Tegra186+), CSI is not a child device to VI and in 
case if either of CSI/VI platform driver register doesn't happen this 
explicit check helps to skip TPG setup. Mostly as device tree changes go 
with driver updates, should not be real issue but in case of wrong 
compatible or missing in device tree to avoid crash added this explicit 
check.

Please consider this v9 for merge.

Thanks

Sowjanya

I've decided to take only patches 6 and 7. Just let me know if for some
reason you want me to merge patch 5 as well, but I think it makes more
sense if you pick that one up.

My pleasure, and it's nice to see this driver going in. Looking forward
to the next phase when sensor support is added!
