This series is the Video Input Interface driver
for Toshiba's ARM SoC, Visconti[0].
This provides DT binding documentation,
device driver, documentation and MAINTAINER files.

A visconti VIIF driver instance exposes
1 media control device file and 3 video device files
for a VIIF hardware.
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
- Introduced ISP subdevice, capture device
- Remove private IOCTLs and add vendor specific V4L2 controls
- Change function name avoiding camelcase and uppercase letters
