This series is the Video Input Interface driver
for Toshiba's ARM SoC, Visconti.
This provides DT binding documentation,
device driver, documentation and MAINTAINER files.
A visconti VIIF driver instance exposes
1 media control device file, 3 video device files for capture
and 2 video device files for controlling image signal processor.
Detailed HW/SW are described in documentation directory.
The VIIF hardware has CSI2 receiver,
image signal processor and DMAC inside.
The subdevice for image signal processor provides
vendor specific V4L2 controls.
The device driver depends on two other drivers under development;
clock framework driver and IOMMU driver.
Corresponding features will be added later.
Best regards,
Yuji
Changelog v2:
- Resend v1 because a patch exceeds size limit.
Changelog v3:
- Add documentation to describe SW and HW
- Adapted to media control framework
