Hello,

this series adds support for the Himax HM1246 image sensor.
The Himax HM1246-AWD is a 1/3.7-Inch CMOS image sensor SoC with an active
array size of 1296 x 976. The datasheet can b
Currently, only the native RAW mode is supported. Other modes and the
internal image signal processing pipeline are not currently supported.
The data sheet is available on the manufacturer’s website [1].
Tested on i.MX8MP hardware. A Toshiba TC358746 bridge was used to convert
the sensor's parallel video output into MIPI signals for the i.MX8MP.

Best regards
 ~Matthias
