From b45a258897a4a37b6cbc0bf1dc21354432f3e8c1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 14 May 2018 20:24:23 +0300 Subject: [PATCH] drm/i915: Clean up DVO pipe select bits MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Parametrize the DVO pipe select bits. For consistency with the new way of doing things, let's read out the pipe select bits even when the port is disable, even though we don't need that behaviour for asserts in this case. v2: Order the defines shift,mask,value (Jani) Reviewed-by: Jani Nikula Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20180514172423.9302-5-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/i915_reg.h | 4 +++- drivers/gpu/drm/i915/intel_dvo.c | 13 ++++--------- 2 files changed, 7 insertions(+), 10 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index dae213d4c13a..196a0eb79272 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -4357,7 +4357,9 @@ enum { #define _DVOC 0x61160 #define DVOC _MMIO(_DVOC) #define DVO_ENABLE (1 << 31) -#define DVO_PIPE_B_SELECT (1 << 30) +#define DVO_PIPE_SEL_SHIFT 30 +#define DVO_PIPE_SEL_MASK (1 << 30) +#define DVO_PIPE_SEL(pipe) ((pipe) << 30) #define DVO_PIPE_STALL_UNUSED (0 << 28) #define DVO_PIPE_STALL (1 << 28) #define DVO_PIPE_STALL_TV (2 << 28) diff --git a/drivers/gpu/drm/i915/intel_dvo.c b/drivers/gpu/drm/i915/intel_dvo.c index eb0c559b2715..a86f0398570f 100644 --- a/drivers/gpu/drm/i915/intel_dvo.c +++ b/drivers/gpu/drm/i915/intel_dvo.c @@ -137,19 +137,15 @@ static bool intel_dvo_connector_get_hw_state(struct intel_connector *connector) static bool intel_dvo_get_hw_state(struct intel_encoder *encoder, enum pipe *pipe) { - struct drm_device *dev = encoder->base.dev; - struct drm_i915_private *dev_priv = to_i915(dev); + struct drm_i915_private *dev_priv = to_i915(encoder->base.dev); struct intel_dvo *intel_dvo = enc_to_dvo(encoder); u32 tmp; tmp = I915_READ(intel_dvo->dev.dvo_reg); - if (!(tmp & DVO_ENABLE)) - return false; - - *pipe = PORT_TO_PIPE(tmp); + *pipe = (tmp & DVO_PIPE_SEL_MASK) >> DVO_PIPE_SEL_SHIFT; - return true; + return tmp & DVO_ENABLE; } static void intel_dvo_get_config(struct intel_encoder *encoder, @@ -276,8 +272,7 @@ static void intel_dvo_pre_enable(struct intel_encoder *encoder, dvo_val |= DVO_DATA_ORDER_FP | DVO_BORDER_ENABLE | DVO_BLANK_ACTIVE_HIGH; - if (pipe == 1) - dvo_val |= DVO_PIPE_B_SELECT; + dvo_val |= DVO_PIPE_SEL(pipe); dvo_val |= DVO_PIPE_STALL; if (adjusted_mode->flags & DRM_MODE_FLAG_PHSYNC) dvo_val |= DVO_HSYNC_ACTIVE_HIGH; -- 2.30.2
