OK - talked with Ville a bit on this and did some of my own research, I actually think that moving i2c to drm_dp_aux_init() is the right decision for the time being. The reasoning behind this being that as shown by my previous work of fixing drivers that call drm_dp_aux_register() too early - it seems like there's already been drivers that have been working just fine with setting up the i2c device before DRM registration.
In the future, it'd probably be better if we can split up i2c_add_adapter() into an init and register function - but we'll have to talk with the i2c maintainers to see if this is acceptable w/ them On Thu, 2021-04-22 at 13:18 -0400, Lyude Paul wrote: > On Tue, 2021-04-20 at 02:16 +0300, Ville Syrjälä wrote: > > > > The init vs. register split is intentional.
