[RFC PATCH v3 0/6] Add Tegra driver for video capture

From: Sowjanya Komatineni
Date: Fri Feb 14 2020 - 13:24:19 EST

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.

[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.
- updated capture thread to wakeup done thread for MW_ACK wait only
on receiving frame start. This also avoid possible race b/w frames
FS and done thread waiting for previous frame MW_ACK when previous
frame FS timeouts.
- Added VI CSI recovery incase of frame sync timeout to have it clean
for next streaming.
- 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
