From 582d79f34330db4ccee85620cf95ee7ccb9a0d01 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 27 May 2024 15:57:50 +0200 Subject: drm/connector: Introduce an HDMI connector initialization function A lot of the various HDMI drivers duplicate some logic that depends on the HDMI spec itself and not really a particular hardware implementation. 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. In the next patches, we'll add a lot of infrastructure around the drm_connector and drm_connector_state structures, which will allow to abstract away the duplicated logic. This infrastructure comes with a few requirements though, and thus we need a new initialization function. Hopefully, this will make drivers simpler to handle, and their behaviour more consistent.
