Hello All,
This series add support for Allied Vision Alvium camera.
The Alvium camera is shipped with sensor + isp in the same housing.
The camera can be equipped with one out of various sensor and abstract
the user from this. Camera is connected via MIPI CSI-2.
Working on top of Ideas on Board (branch: ideasonboard/v6.2/isi)
I'm able to test the driver on imx8mp-evk.
I collect also some patches to enable HDMI on imx8mp-evk from Pengutronix
(branch: pengutronix-imx8mp-hdmi)
I collect the patchset required to enable ISI + HDMI on imx8mp-evk into
the following branch from Avnet Silica Software & Services EMEA [1].
Some documentation on testing ISP and ISI of imx8mp-evk here [2].
Thanks all for the great work!

The Alvium camera is shipped with sensor + isp in the same housing.
The camera can be equipped with one out of various sensor and abstract
the user from this. Camera is connected via MIPI CSI-2.
Most of the camera module features are supported, with the main exception
being fw update.
The driver provides all mandatory, optional and recommended V4L2 controls
for maximum compatibility with libcamera
