Subject: [PATCH 0/3] Fix drm suspend and resume issue 1. When the hardwire components on crtc is using GCE to configure their register, cmdq_suspend may be called. So add cmdq_mbox_flush to clear all tasks and release GCE clocks before cmdq_suspend. 2. The suspend and resume order of components on crtc can be guaranteed by the same power-domain, but cmdq can not. So add devlink to cmdq dev make sure the order of suspend and resume: cmdq_suspend is latter than drm_suspend and cmdq_resume is earlier than drm_resume. jason-jh.lin (3): mialbox: move cmdq suspend,resume and remove after cmdq_mbox_flush mailbox: add cmdq_mbox_flush to clear all task before suspend drm/mediatek: add devlink to cmdq dev drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 13 ++++ drivers/mailbox/mtk-cmdq-mailbox.c | 81 ++++++++++++------------- 2 files changed, 52 insertions(+), 42 deletions(-) -- 2.18.0
