Subject: [PATCH v3 0/3] Add IMX290 CMOS image sensor support

Hello,

This patchset adds support for IMX290 CMOS image sensor from Sony.
Sensor can be programmed through I2C and 4-wire interface but the
current driver only supports I2C interface. Also, the sensor is
capable of outputting frames in following 3 interfaces:

* CMOS logic parallel SDR output
* Low voltage LVDS serial DDR output
* CSI-2 serial data output

But the current driver only supports CSI-2 output available from 4 lanes.
In the case of sensor resolution, driver only supports 1920x1080 and
1280x720 at mid data rate of 445.5 Mpbs.

The driver has been validated using Framos IMX290 module interfaced to
96Boards Dragonboard410c.

Thanks,
Mani

Changes in v3:

As per the review by Sakari:

* Switched to pm runtime
* Used link-frequency property
* Removed useless read calls from buffered read function
* Some other misc changes to the driver and binding

Changes in v2:

* Added Reviewed-by tag from Rob for bindings patch
