From 4aa3df7149a00cb061d2ba74e2136cd14a6d885a Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 24 Nov 2014 16:27:13 +0100 Subject: [PATCH] drm/tegra: Atomic conversion, phase 1 Implement initial atomic state handling. Hook up the CRTCs, planes' and connectors' ->atomic_destroy_state() callback to ensure that the atomic state objects don't leak. Furthermore the CRTC now implements the ->mode_set_nofb() callback that is used by new helpers to implement ->mode_set() and ->mode_set_base(). These new helpers also make use of the new plane helper functions which the driver now provides.
