Dave Stevenson 580d15a53b media: i2c: ov5647: Add control of V4L2_CID_HBLANK
The driver did expose V4L2_CID_HBLANK, but as a READ_ONLY control.

The sensor only uses the HTS register to control the line length,
so convert this control to read/write, with the appropriate ranges.
Adopt the old fixed values as the minimum values permitted in each
mode to avoid issues of it not streaming.

This should allow exposure times up to ~3 seconds (up from ~1sec).

Linux kernel

There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.

In order to build the documentation, use make htmldocs or make pdfdocs. The formatted documentation can also be read online at:

https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
