On various Lenovo Thinkpad models with an ov2740 sensor the 360 MHz link frequency is not supported. Add support for 180 MHz link frequency, even though this has half the pixel clock, this supports the same framerate by using half the VTS value (significantly reducing the amount of empty lines send during vblank). Normally if there are multiple link-frequencies then the sensor driver choses the lowest link-frequency still usable for the chosen resolution. In this case the board supports only 1 link-frequency. Which frequency is supported is checked in ov2740_check_hwcfg() and then a different set of supported_modes (using only the supported link-freq) is selected. The register settings for this were taken from the ov2740 sensor driver in the out of tree IPU6 driver: https://github.com/intel/ipu6-drivers/ Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> |

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.
