If you only need build-testing, you could have a simple wrapper like
const struct drm_format_info *ipu_format_info(u32 format) { static const struct drm_format_info invalid = {};
if (!IS_REACHABLE(CONFIG_DRM)) return &invalid; return drm_format_info(format);}
That should work fine. Both ipu_prg_format_supported and ipu_prg_channel_configure are only ever called by DRM code.
Ok, in that case, I think we should just make the compilation of PRE and PRG conditional and leave them out when DRM is not built-in (be aware of the case of DRM=m, IPU=y).
Maybe we should just:
config IMX_IPUV3_CORE depends on DRM || !DRM # if DRM=m, this can't be 'y'
