From 1f8a21af2171909d02257e715a47fda4cb000d81 Mon Sep 17 00:00:00 2001 From: Jernej Skrabec Date: Sun, 24 Apr 2022 11:26:26 -0500 Subject: [PATCH] sun4i/drm: sun8i: use mode_set engine callback Newly introduced mode_set callback in engine structure is a much better place for setting mixer output size and interlace mode for the following reasons: 1. Aforementioned properties change only when mode changes, so it's enough to be set only once per mode set. Currently it's done whenever properties of primary plane are changed. 2. It's assumed that primary plane will always cover whole screen. While this is true most of the time, it's not always. DE2/3 planes are universal and mostly equal in functionality. There is no reason to add artificial limitation to primary planes. 3. The current code only works for UI layers, but some mixers do not have any UI layers.
