From 7e66bcf2656ad2e53de939c5a5f211288a332ede Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Thu, 20 Aug 2015 10:47:39 +0300 Subject: [PATCH] drm/i915: add common intel_digital_port_connected function Add a common intel_digital_port_connected() that splits out to functions for different platforms. No functional changes. v2: make the function return a boolean Signed-off-by: Jani Nikula Reviewed-by: Durgadoss R Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_dp.c | 41 ++++++++++++++++++--------------- 1 file changed, 22 insertions(+), 19 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index 8c8070ee26d7..1db7e1edd00d 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -4480,13 +4480,6 @@ edp_detect(struct intel_dp *intel_dp) return status; } -/* - * ibx_digital_port_connected - is the specified port connected? - * @dev_priv: i915 private structure - * @port: the port to test - * - * Returns true if @port is connected, false otherwise. - */ static bool ibx_digital_port_connected(struct drm_i915_private *dev_priv, struct intel_digital_port *port) { @@ -4531,13 +4524,12 @@ static bool ibx_digital_port_connected(struct drm_i915_private *dev_priv, return I915_READ(SDEISR) & bit; } -static bool g4x_digital_port_connected(struct drm_device *dev, +static bool g4x_digital_port_connected(struct drm_i915_private *dev_priv, struct intel_digital_port *port) { - struct drm_i915_private *dev_priv = dev->dev_private; uint32_t bit; - if (IS_VALLEYVIEW(dev)) { + if (IS_VALLEYVIEW(dev_priv)) { switch (port->port) { case PORT_B: bit = PORTB_HOTPLUG_LIVE_STATUS_VLV; @@ -4572,6 +4564,22 @@ static bool g4x_digital_port_connected(struct drm_device *dev, return I915_READ(PORT_HOTPLUG_STAT) & bit; } +/* + * intel_digital_port_connected - is the specified port connected? + * @dev_priv: i915 private structure + * @port: the port to test + * + * Return %true if @port is connected, %false otherwise. + */ +static bool intel_digital_port_connected(struct drm_i915_private *dev_priv, + struct intel_digital_port *port) +{ + if (HAS_PCH_SPLIT(dev_priv)) + return ibx_digital_port_connected(dev_priv, port); + else + return g4x_digital_port_connected(dev_priv, port); +} + static enum drm_connector_status ironlake_dp_detect(struct intel_dp *intel_dp) { @@ -4579,7 +4587,7 @@ ironlake_dp_detect(struct intel_dp *intel_dp) struct drm_i915_private *dev_priv = dev->dev_private; struct intel_digital_port *intel_dig_port = dp_to_dig_port(intel_dp); - if (!ibx_digital_port_connected(dev_priv, intel_dig_port)) + if (!intel_digital_port_connected(dev_priv, intel_dig_port)) return connector_status_disconnected; return intel_dp_detect_dpcd(intel_dp); @@ -4601,7 +4609,7 @@ g4x_dp_detect(struct intel_dp *intel_dp) return status; } - if (!g4x_digital_port_connected(dev, intel_dig_port)) + if (!intel_digital_port_connected(dev->dev_private, intel_dig_port)) return connector_status_disconnected; return intel_dp_detect_dpcd(intel_dp); @@ -5064,13 +5072,8 @@ intel_dp_hpd_pulse(struct intel_digital_port *intel_dig_port, bool long_hpd) /* indicate that we need to restart link training */ intel_dp->train_set_valid = false; - if (HAS_PCH_SPLIT(dev)) { - if (!ibx_digital_port_connected(dev_priv, intel_dig_port)) - goto mst_fail; - } else { - if (!g4x_digital_port_connected(dev, intel_dig_port)) - goto mst_fail; - } + if (!intel_digital_port_connected(dev_priv, intel_dig_port)) + goto mst_fail; if (!intel_dp_get_dpcd(intel_dp)) { goto mst_fail; -- 2.20.1
