Hmm, the imx471 driver is still pending upstream:

https://lore.kernel.org/linux-media/20260629074026.35490-5-hpa@xxxxxxxxxx/

As part of this series.

Please just use the standardized "avdd" in that driver instead
of "vana" (which also seems to refer to the analog supply vdd,
which is what avdd stands for).

Then this whole patch is unnecessary and can be dropped from
this series.

Regards,

Hans
