From mboxrd@z Thu Jan 1 00:00:00 1970 From: paul.kocialkowski@bootlin.com (Paul Kocialkowski) Date: Fri, 23 Nov 2018 10:25:08 +0100 Subject: [PATCH v2 36/43] drm/sun4i: layer: Add tiled modifier support and helper In-Reply-To: <20181123092515.2511-1-paul.kocialkowski@bootlin.com> References: <20181123092515.2511-1-paul.kocialkowski@bootlin.com> Message-ID: <20181123092515.2511-37-paul.kocialkowski@bootlin.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Paul Kocialkowski This introduces a list of supported modifiers for the driver, that includes the Allwinner tiled modifier, as well as a format_mod_supported callback. The callback uses both the backend and frontend helpers to indicate per-format modifier support (including for the linear modifier).
