Can you split this change into a separate patch? It needs an Acked-by from one of the device tree binding maintainers, so make sure to Cc them when you repost. scripts/get_maintainer.pl will list them for you. > +static const struct display_timing okaya_rs800480t_7x0gp_timing = { > + .pixelclock = { 30000000, 30000000, 40000000 }, > + .hactive = { 800, 800, 800 }, > + .hfront_porch = { 40, 40, 40 }, > + .hback_porch = { 40, 40, 40 }, > + .hsync_len = { 1, 48, 48 }, > + .vactive = { 480, 480, 480 }, > + .vfront_porch = { 13, 13, 13 }, > + .vback_porch = { 29, 29, 29 }, > + .vsync_len = { 3, 3, 3 }, It strikes me as odd that the porches and VSYNC width should be fixed for the panel. Is this really the case? Thierry
