Subject: [PATCH v2 RESEND 15/24] drm/exynos: add plane update/disable callbacks for planes
Date: Wed, 20 Mar 2019 14:06:58 +0100	[thread overview]
Message-ID: <20190320130707.25161-16-a.hajda@samsung.com> (raw)
In-Reply-To: <20190320130707.25161-1-a.hajda@samsung.com>

Display controllers in Exynos beside native planes/windows can use external
planes provided by other IPs - GSCALER, FIMD, VPP. To add support to them
we will need plane specific callbacks.
