Subject: [PATCH v7 0/2] media: Add support for ST VD55G1 camera sensor

Hi,

This serie adds support for the STMicroelectronics VD55G1 camera sensor.
The VD55G1 is a monochrome global shutter camera with a 804x704 maximum
resolution with RAW8 and RAW10 bytes per pixel.
Datasheets and other documentation can be found at st.com [1].
A lot of inspiration was taken from the imx219 and the vd56g3 serie.
It is compatible with libcamera. Tested on Raspberry Pi 4 and 5, with and
without libcamera.

Regards,
Benjamin
