This implements suspend/resume using the atomic update supsend/resume helpers instead of the current implementation which uses regcache. The code has been tested on a Colibri VF61 using the freeze suspend mode. This also avoids a lockdep warning by not using register caching at all and therefor obsoletes this patch: https://lkml.org/lkml/2016/3/24/281 Stefan Agner (6): drm/fb_cma_helper: add suspend helper drm/fsl-dcu: store layer registers in soc_data drm/fsl-dcu: move layer initialization to plane file drm/fsl-dcu: use clk helpers drm/fsl-dcu: implement suspend/resume using atomic helpers drm/fsl-dcu: disable vblank events on CRTC disable drivers/gpu/drm/drm_fb_cma_helper.c | 15 ++++++++++ drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_crtc.c | 21 ++++--------- drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c | 46 ++++++++++++++++++++++------- drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.h | 2 ++ drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_plane.c | 16 ++++++++++ drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_plane.h | 1 + include/drm/drm_fb_cma_helper.h | 1 + 7 files changed, 76 insertions(+), 26 deletions(-) -- 2.8.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
