The Synopsys DesignWare MIPI CSI-2 Receiver is integrated into
recent Rockchip SoCs, such as the RK3568 and the RK3588.
Enable the driver for it in the default configuration.

... and used on boards foo bar.

(becuse we take defconfig for boards, not for SoCs - if there is no
single board using it, then it should not be enabled because it means
you do it for downstream which simply does not exist for us).

foo bar = pretty much any recent board with a Rockchip SoC on it...
(plus NXP users, as there is a series by Frank in the works)

... but there is not yet a mainline example. Next item on my TODO list
is to send out basic RK3588 VICAP support including the device tree bits
for the Radxa ROCK 5B+ plus camera modules. Should I include the patch
in that series? Or wait until that series has been accepted? Or will you
just take my word for it that there will be plenty of boards using that
receiver in near future?

Best regards,
Michael

Then why do we want it in the mainline? Answer: there is no reason.

We do not support downstream setups with mainline defconfigs.
