From c1bcad9d16831859373d8f579fa1e146409f9960 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 17 Mar 2010 19:50:59 -0400 Subject: [PATCH] drm/radeon/kms: remove lvds quirks - no longer needed with the latest new pll algo fixes. - also don't use lcd pll limits. They don't seem to work well for all systems. If we have a case where they are useful, we can set the flag for that case. fixes fdo bug 27083 Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie --- drivers/gpu/drm/radeon/atombios_crtc.c | 6 ------ drivers/gpu/drm/radeon/radeon_atombios.c | 27 --------------------------- 2 files changed, 33 deletions(-) diff --git a/drivers/gpu/drm/radeon/atombios_crtc.c b/drivers/gpu/drm/radeon/atombios_crtc.c index 7c30e2e..94aa6b2 100644 --- a/drivers/gpu/drm/radeon/atombios_crtc.c +++ b/drivers/gpu/drm/radeon/atombios_crtc.c @@ -521,12 +521,6 @@ static u32 atombios_adjust_pll(struct drm_crtc *crtc, /* DVO wants 2x pixel clock if the DVO chip is in 12 bit mode */ if (radeon_encoder->encoder_id == ENCODER_OBJECT_ID_INTERNAL_KLDSCP_DVO1) adjusted_clock = mode->clock * 2; - /* LVDS PLL quirks */ - if (encoder->encoder_type == DRM_MODE_ENCODER_LVDS) { - struct radeon_encoder_atom_dig *dig = radeon_encoder->enc_priv; - pll->algo = dig->pll_algo; - pll->flags |= RADEON_PLL_IS_LCD; - } } else { if (encoder->encoder_type != DRM_MODE_ENCODER_DAC) pll->flags |= RADEON_PLL_NO_ODD_POST_DIV; diff --git a/drivers/gpu/drm/radeon/radeon_atombios.c b/drivers/gpu/drm/radeon/radeon_atombios.c index 92e6886..3733cb7 100644 --- a/drivers/gpu/drm/radeon/radeon_atombios.c +++ b/drivers/gpu/drm/radeon/radeon_atombios.c @@ -1128,30 +1128,6 @@ static struct radeon_atom_ss *radeon_atombios_get_ss_info(struct return ss; } -static void radeon_atom_apply_lvds_quirks(struct drm_device *dev, - struct radeon_encoder_atom_dig *lvds) -{ - - /* Toshiba A300-1BU laptop panel doesn't like new pll divider algo */ - if ((dev->pdev->device == 0x95c4) && - (dev->pdev->subsystem_vendor == 0x1179) && - (dev->pdev->subsystem_device == 0xff50)) { - if ((lvds->native_mode.hdisplay == 1280) && - (lvds->native_mode.vdisplay == 800)) - lvds->pll_algo = PLL_ALGO_LEGACY; - } - - /* Dell Studio 15 laptop panel doesn't like new pll divider algo */ - if ((dev->pdev->device == 0x95c4) && - (dev->pdev->subsystem_vendor == 0x1028) && - (dev->pdev->subsystem_device == 0x029f)) { - if ((lvds->native_mode.hdisplay == 1280) && - (lvds->native_mode.vdisplay == 800)) - lvds->pll_algo = PLL_ALGO_LEGACY; - } - -} - union lvds_info { struct _ATOM_LVDS_INFO info; struct _ATOM_LVDS_INFO_V12 info_12; @@ -1234,9 +1210,6 @@ struct radeon_encoder_atom_dig *radeon_atombios_get_lvds_info(struct lvds->pll_algo = PLL_ALGO_LEGACY; } - /* LVDS quirks */ - radeon_atom_apply_lvds_quirks(dev, lvds); - encoder->native_mode = lvds->native_mode; } return lvds; -- 2.7.4
