From 74a3dba26c606adc29f6ba6484d5cdaaf877cccc Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Wed, 10 Jan 2018 16:20:01 +0100 Subject: drm/imx: ipuv3-plane: add zpos property Add a zpos property to planes. Call drm_atomic_helper_check() instead of calling drm_atomic_helper_check_modeset() and drm_atomic_check_planes() manually. This effectively adds a call to drm_atomic_normalize_zpos() before checking planes. Reorder atomic update to allow changing plane zpos without modeset. Note that the initial zpos is set in ipu_plane_state_reset(). The initial value set in ipu_plane_init() is just for show. The zpos parameter of drm_plane_create_zpos_property() is ignored because the newly created plane do not have state yet.
