From 546230dfa483f6d1f188d1a1a20122ecabf82816 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 16 Apr 2012 22:43:42 +0100 Subject: drm/i915/dp: Flush any outstanding work to turn the VDD off commit 17038de5f16569a25343cf68668f3b657eafb00e upstream. As we may kick off a delayed workqueue task to switch of the VDD lines, we need to complete that task prior to turning off the panel (which itself depends upon VDD being off). v2: Don't cancel the outstanding work as this may trigger a deadlock Signed-off-by: Chris Wilson Cc: Keith Packard Signed-off-by: Daniel Vetter Signed-off-by: Greg Kroah-Hartman --- drivers/gpu/drm/i915/intel_dp.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/gpu/drm') diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index 4b637919f74..3a866f0410b 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -1149,6 +1149,7 @@ static void ironlake_edp_panel_off(struct intel_dp *intel_dp) DRM_DEBUG_KMS("Turn eDP power off\n"); WARN(intel_dp->want_panel_vdd, "Cannot turn power off while VDD is on\n"); + ironlake_panel_vdd_off_sync(intel_dp); /* finish any pending work */ pp = ironlake_get_pp_control(dev_priv); pp &= ~(POWER_TARGET_ON | EDP_FORCE_VDD | PANEL_POWER_RESET | EDP_BLC_ENABLE); -- cgit v1.2.3
