Subject: [PATCH 4/9] drm/ast: Split ast_set_ext_reg() into color and threshold function
Date: Mon, 28 Oct 2019 16:49:23 +0100	[thread overview]
Message-ID: <20191028154928.4058-5-tzimmermann@suse.de> (raw)
In-Reply-To: <20191028154928.4058-1-tzimmermann@suse.de>

In ast_set_ext_reg() sets several framebuffer options and CRT threshold
parameters. The former is mostly state of the primary plane; the latter
is constant. Hence, split the function in two and make it work with
atomic modesetting.
