Hello Laurent, Revision 1.00 has brought several updates on how to handle some registers in the DU. In particular - ESCR cannot be written for channels with a DPLL - OTAR cannot be written for channels without a digital output pad - routing superimposition processor output to pincontrollers through DORCR2 register cannot be performed for channels of group 1 - The plane super-imposition register PnMR can be written to groups with more than 1 channel. Patches applied on top of your latest drm/du/next branch. Tested on Salvator-X M3-W with VGA and HDMI output. Tested on Salvator-XS M3-N with VGA and HDMI output. No visible regression, but if you have ideas on how to better verify this please let me know. Thanks j Jacopo Mondi (4): drm: rcar-du: Do not write ESCR for DPLL channels drm: rcar-du: Write OTAR for DPAD channels only drm: rcar-du: Fix handling of DORCR for group 1 drm: rcar-du: Fix handling of PnMR register drivers/gpu/drm/rcar-du/rcar_du_crtc.c | 18 +++++++++++------- drivers/gpu/drm/rcar-du/rcar_du_group.c | 19 ++++++++++++++++--- drivers/gpu/drm/rcar-du/rcar_du_plane.c | 13 +++++++++++-- 3 files changed, 38 insertions(+), 12 deletions(-) -- 2.7.4 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
