freedesktop - Feb 2023 - [fdo] Necessity for using the component helper library for DRM drivers.

Hi,
I am new to the Linux and DRM framework in Linux. I was going through some
reference drivers like VC4, exynos, etnaviv, Renesas (rcar-du), rockchip. Almost
in all these cases, they use a component helpers to glue together the different
IPs under the hood of a pseudo master driver. It should also be possible to let
the individual components probe on their own, and they individually register
with the DRM core to provide the required functionality.
If an SoC contains different IP blocks to render and driver the display, should
we not go with the basic probing for each individual IP and then register with
the DRM core, rather than bringing it under one hood. Are there any inherent
benefits for doing things the other way?

Sorry for asking if it is too obvious.

Thanks
