From a7a8569adc035cf74a3b82d00ba266ac9b249a15 Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime@cerno.tech>
Date: Tue, 15 Dec 2020 16:42:36 +0100
Subject: [PATCH] drm/vc4: Pass the atomic state to encoder hooks
We'll need to access the connector state in our encoder setup, so let's
just pass the whole DRM state to our private encoder hooks.
Acked-by: Thomas Zimmermann <tzimmermann@suse.de>
