ping. I have verified (on linux-next-20221103) that this is still needed. Thanks.

Could you explain what this is doing please? I know you've explained above that it fixes it to optionally depend on DRM_RCAR_MIPI_DSI ... but it's not making sense to me.

But that the it can also be satisfied if is not set DRM_RCAR_MIPI_DSI. This is usually used to make sure that you don't end with a configuration where DRM_RCAR_MIPI_DSI=y and DRM_RCAR_DU=m or DRM_RCAR_MIPI_DSI=m and DRM_RCAR_DU=y. Randy, I think that it's more idiomatic though to it express as following: depends on DRM_RCAR_MIPI_DSI || !DRM_RCAR_MIPI_DSI

I never build modules, always builtin - so it doesn't hit me ;-) Anyway - it certainly makes sense now I think so either as posted, or with the idiomatic proposal from Javier: Reviewed-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> > > -- > Best regards, > > Javier Martinez Canillas > Core Platforms > Red Hat >

I don't have a strong opinion, I just thought the latter was more idiomatic but you said that both are used alike.

When CONFIG_DRM_RCAR_DU=y and CONFIG_DRM_RCAR_MIPI_DSI=m, calls from the builtin driver to the mipi driver fail due to linker errors. Since the RCAR_MIPI_DSI driver is not always required, fix the build error by making DRM_RCAR_DU optionally depend on the RCAR_MIPI_DSI Kconfig symbol.
