From 35dad45d5cad3c9ca8d6a338cbf668cd7ea86469 Mon Sep 17 00:00:00 2001 From: David Francis Date: Tue, 20 Nov 2018 09:42:58 -0500 Subject: drm/amd/display: Detach backlight from stream [Why] Backlight is conceptually a property of links, not streams. All backlight programming is done on links, but there is a stream property bl_pwm_level that is used to restore backlight on dpms on and s3 resume. This is unnecessary, as backlight is already restored by hardware with no driver intervention. [How] Remove bl_pwm_level, and the stream argument to set_backlight Bug: https://bugs.freedesktop.org/show_bug.cgi?id=109375 Signed-off-by: David Francis Reviewed-by: Harry Wentland Acked-by: Anthony Koo Acked-by: Leo Li Signed-off-by: Alex Deucher (cherry picked from commit 923fe4951282cbdfce05186c10380bbc45b5e03b) --- drivers/gpu/drm/amd/display/dc/dc_stream.h | 1 - 1 file changed, 1 deletion(-) (limited to 'drivers/gpu/drm/amd/display/dc/dc_stream.h') diff --git a/drivers/gpu/drm/amd/display/dc/dc_stream.h b/drivers/gpu/drm/amd/display/dc/dc_stream.h index be34d638e15d..d70c9e1cda3d 100644 --- a/drivers/gpu/drm/amd/display/dc/dc_stream.h +++ b/drivers/gpu/drm/amd/display/dc/dc_stream.h @@ -91,7 +91,6 @@ struct dc_stream_state { /* DMCU info */ unsigned int abm_level; - unsigned int bl_pwm_level; /* from core_stream struct */ struct dc_context *ctx; -- cgit v1.2.3
