Tegra20 and other Tegra SoCs have a video input (VI) peripheral that can
receive from either MIPI CSI-2 or parallel video (called respectively "CSI"
and "VIP" in the documentation). The kernel currently has a staging driver
for Tegra210 CSI capture. This patch set adds support for Tegra20 VIP
capture.
Unfortunately I had no real documentation available to base this work on,
and I started from a working downstream 3.1 kernel, that I have heavily
reworked to fit into the existing tegra-video driver. The existing code
appears written with the intent of being modular and allow adding new input
mechanisms and new SoCs while keeping a unique VI core module. However its
modularity and extensibility was not enough to add Tegra20 VIP support, so
I added some hooks to turn hard-coded behaviour into per-SoC or per-bus
customizable code. There are also some fixes, some generic cleanups and DT
bindings.
Quick tour of the patches:
* Device tree bindings and minor DTS improvements
01. dt-bindings: display: tegra: add bindings for Tegra20 VIP
02. dt-bindings: display: tegra: vi: add 'vip' property and example
03. ARM: dts: tegra20: add label to nvidia,tegra20-vi node
04. ARM: dts: tegra20-tamonten: add label to avdd_vdac regulator
* A fix
05. staging: media: tegra-video: fix .vidioc_enum_fmt_vid_cap to return all formats
* Minor improvements to logging, comments, cleanups
06. staging: media: tegra-video: improve documentation of tegra_video_format fields
07. staging: media: tegra-video: document tegra_channel_get_remote_source_subdev
08. staging: media: tegra-video: fix typos in comment
09. staging: media: tegra-video: improve error messages
10. staging: media: tegra-video: slightly simplify cleanup on errors
11. staging: media: tegra-video: move private struct declaration to C file
12. staging: media: tegra-video: remove unneeded include
* Preparation to make the VI module generic enough to host Tegra20 and VIP
13. staging: media: tegra-video: Kconfig: allow TPG only on Tegra210
14. staging: media: tegra-video: move tegra_channel_fmt_align to a per-soc op
15. staging: media: tegra-video: move default format to soc-specific data
16. staging: media: tegra-video: move MIPI calibration calls from VI to CSI
17. staging: media: tegra-video: add a per-soc enable/disable op
18. staging: media: tegra-video: move syncpt init/free to a per-soc op
19. staging: media: tegra-video: add syncpts for Tegra20 to struct tegra_vi
20. staging: media: tegra-video: add hooks for planar YUV and H/V flip
21. staging: media: tegra-video: add H/V flip controls
* Implementation of VIP and Tegra20
22. staging: media: tegra-video: add support for VIP (parallel video input)
23. staging: media: tegra-video: add tegra20 variant
Enjoy!
