The various chips have slight differences in how they handle and store ddc i2c buses. This series tries to put the main i2c adapter for ddc into the drm_connector->ddc pointer. This makes it easier to unify the code for the different encoders in upcoming series. Oaktrail HDMI and PSB SDVO are not included.
For the series: Acked-by: Thomas Zimmermann <tzimmermann@xxxxxxx>I recently posted two patches for simplifying EDID handing. The new DRM helper for .get_modes fetches the EDID from conenctor->ddc. [1] The helper for .detect_ctx uses .get_modes and the EDID data to poll the connector status. [2] gma500 is one of the candidates for using these helpers. If you like the idea, I'd welcome a follow-up patchset.
