From 2b58e98d42af854037439f51bd89f83dbfa8e30d Mon Sep 17 00:00:00 2001 From: Liu Ying Date: Mon, 29 Aug 2016 17:12:03 +0800 Subject: drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commit Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.
