Output BPC or format selection, infoframe generation are good examples of such areas. This creates a lot of boilerplate, with a lot of variations, which makes it hard for userspace to rely on, and makes it difficult to get it right for drivers. Let's create a new connector variant specifically dedicated to HDMI controllers that will allow to abstract away the duplicated logic. Hopefully, this will make drivers simpler to handle, and their behaviour more consistent.

The vc4 driver then implemented the same property with the same semantics. KWin has support for it, and a PR for mutter is also there to support it. Both drivers implementing the same property with the same semantics, plus the userspace having support for it, is proof enough that it's pretty much a de-facto standard now and we can provide helpers for it. Let's plumb it into the newly created HDMI connector.

On "embedded"-grade display controllers, it will typically be lower than what high-grade monitors can provide these days, so drivers will filter the TMDS character rate based on the controller capabilities. To make that easier to handle for drivers, let's provide an optional hook to be implemented by drivers so they can tell the HDMI controller helpers if a given TMDS character rate is reachable for them or not. This will then be useful to figure out the best format and bpc count for a given mode.

This leads to discrepancies with how drivers generate them, and which are actually sent. Now that we have everything needed to generate them in the HDMI connector state, we can generate them in our common logic so that drivers can simply reuse what we precomputed.

In parallel, there's been some interest in creating an infoframe-decode tool similar to edid-decode. Both would be much easier if we were to expose the infoframes programmed in the hardware. It won't be perfect since we have no guarantee that it's actually what goes through the wire, but it's the best we can do.
