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.
[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 incase 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

Tegra210 uses PLLD out internally for CSI TPG.
This patch adds clk id for this CSI TPG clock from PLLD.

Tegra210 CSI hardware internally uses PLLD for internal test pattern
generator logic.
PLLD_BASE register in CAR has a bit CSI_CLK_SOURCE to enable PLLD
out to CSI during TPG mode.
This patch adds this CSI TPG clock gate to Tegra210 clock driver
to allow Tegra video driver to ungate CSI TPG clock during TPG mode
and gate during non TPG mode.
