Daniel Vetter e8cb455876 drm/i915/dp: convert to encoder disable/enable ... DP is the first encoder which isn't simple. As commit d240f20f54 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Fri Aug 13 15:43:26 2010 -0700 drm/i915: make sure eDP PLL is enabled at the right time discovered, we need to enable the eDP PLL for the cpu port _before_ we enable the pipes and planes. After a few more commits the current solution is to enable the PLL in the dp mode_set function (because this is the only encoder callback the crtc helper code calls before it calls the crtc's commit function). Now I suspect that we actually should enable/disable the entire cpu eDP port before/after planes, but thanks to how the crtc helper code assumes that you can disable an encoder without disabling it's crtc right away, this won't work. The result is that the current prepare/commit hooks don't touch the eDP PLL, but instead it get's frobbed in dp_mode_set and in the dp dpms function. Hence we need to keep things (at least for now) bug-for-bug compatible by using our own special dp dpms function and keep everything else more-or-less as-is (just using our own infrastrucutre now). This mess can only be cleaned up once we control the entire modeset sequence and can move things around freely. v2: Squash unsupported dpms modes to OFF at the beginning of the DP dpms function. v3: Need to set the dpms state to off in dp_disable, otherwise this breaks the newly added WARNs ... v4: Rebased against edp panel off sequence changes in 3.6-rc2 Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2012-09-06 07:54:21 +02:00
