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
