From 0d90c61ab9b043f49dcb544e170ab4411b6b3408 Mon Sep 17 00:00:00 2001 From: Madhav Chauhan Date: Tue, 30 Oct 2018 13:56:08 +0200 Subject: [PATCH] drm/i915/dsi: move connector mode functions to common file Move DSI connector functions to intel_dsi.c and make them available to both legacy and ICL DSI. v2 by Jani: - Move the functions to intel_dsi.c - Don't reuse intel_dsi_connector_destroy() Signed-off-by: Madhav Chauhan Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/99244c6edf4a26ef2e279c7160d22dbbb5cd95f2.1540900289.git.jani.nikula@intel.com --- drivers/gpu/drm/i915/intel_dsi.c | 47 +++++++++++++++++++++++++++++++ drivers/gpu/drm/i915/intel_dsi.h | 3 ++ drivers/gpu/drm/i915/vlv_dsi.c | 48 -------------------------------- 3 files changed, 50 insertions(+), 48 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_dsi.c b/drivers/gpu/drm/i915/intel_dsi.c index 97e04c272612..b9d5ef79015e 100644 --- a/drivers/gpu/drm/i915/intel_dsi.c +++ b/drivers/gpu/drm/i915/intel_dsi.c @@ -29,6 +29,53 @@ int intel_dsi_tlpx_ns(const struct intel_dsi *intel_dsi) } } +int intel_dsi_get_modes(struct drm_connector *connector) +{ + struct intel_connector *intel_connector = to_intel_connector(connector); + struct drm_display_mode *mode; + + DRM_DEBUG_KMS("\n"); + + if (!intel_connector->panel.fixed_mode) { + DRM_DEBUG_KMS("no fixed mode\n"); + return 0; + } + + mode = drm_mode_duplicate(connector->dev, + intel_connector->panel.fixed_mode); + if (!mode) { + DRM_DEBUG_KMS("drm_mode_duplicate failed\n"); + return 0; + } + + drm_mode_probed_add(connector, mode); + return 1; +} + +enum drm_mode_status intel_dsi_mode_valid(struct drm_connector *connector, + struct drm_display_mode *mode) +{ + struct intel_connector *intel_connector = to_intel_connector(connector); + const struct drm_display_mode *fixed_mode = intel_connector->panel.fixed_mode; + int max_dotclk = to_i915(connector->dev)->max_dotclk_freq; + + DRM_DEBUG_KMS("\n"); + + if (mode->flags & DRM_MODE_FLAG_DBLSCAN) + return MODE_NO_DBLESCAN; + + if (fixed_mode) { + if (mode->hdisplay > fixed_mode->hdisplay) + return MODE_PANEL; + if (mode->vdisplay > fixed_mode->vdisplay) + return MODE_PANEL; + if (fixed_mode->clock > max_dotclk) + return MODE_CLOCK_HIGH; + } + + return MODE_OK; +} + struct intel_dsi_host *intel_dsi_host_init(struct intel_dsi *intel_dsi, const struct mipi_dsi_host_ops *funcs, enum port port) diff --git a/drivers/gpu/drm/i915/intel_dsi.h b/drivers/gpu/drm/i915/intel_dsi.h index 09f0fa9ccc7d..10fd1582a8e2 100644 --- a/drivers/gpu/drm/i915/intel_dsi.h +++ b/drivers/gpu/drm/i915/intel_dsi.h @@ -152,6 +152,9 @@ int intel_dsi_tlpx_ns(const struct intel_dsi *intel_dsi); /* vlv_dsi.c */ void vlv_dsi_wait_for_fifo_empty(struct intel_dsi *intel_dsi, enum port port); enum mipi_dsi_pixel_format pixel_format_from_register_bits(u32 fmt); +int intel_dsi_get_modes(struct drm_connector *connector); +enum drm_mode_status intel_dsi_mode_valid(struct drm_connector *connector, + struct drm_display_mode *mode); struct intel_dsi_host *intel_dsi_host_init(struct intel_dsi *intel_dsi, const struct mipi_dsi_host_ops *funcs, enum port port); diff --git a/drivers/gpu/drm/i915/vlv_dsi.c b/drivers/gpu/drm/i915/vlv_dsi.c index cbb935a9acf3..bab87b62bc2d 100644 --- a/drivers/gpu/drm/i915/vlv_dsi.c +++ b/drivers/gpu/drm/i915/vlv_dsi.c @@ -1212,31 +1212,6 @@ static void intel_dsi_get_config(struct intel_encoder *encoder, } } -static enum drm_mode_status -intel_dsi_mode_valid(struct drm_connector *connector, - struct drm_display_mode *mode) -{ - struct intel_connector *intel_connector = to_intel_connector(connector); - const struct drm_display_mode *fixed_mode = intel_connector->panel.fixed_mode; - int max_dotclk = to_i915(connector->dev)->max_dotclk_freq; - - DRM_DEBUG_KMS("\n"); - - if (mode->flags & DRM_MODE_FLAG_DBLSCAN) - return MODE_NO_DBLESCAN; - - if (fixed_mode) { - if (mode->hdisplay > fixed_mode->hdisplay) - return MODE_PANEL; - if (mode->vdisplay > fixed_mode->vdisplay) - return MODE_PANEL; - if (fixed_mode->clock > max_dotclk) - return MODE_CLOCK_HIGH; - } - - return MODE_OK; -} - /* return txclkesc cycles in terms of divider and duration in us */ static u16 txclkesc(u32 divider, unsigned int us) { @@ -1559,29 +1534,6 @@ static void intel_dsi_unprepare(struct intel_encoder *encoder) } } -static int intel_dsi_get_modes(struct drm_connector *connector) -{ - struct intel_connector *intel_connector = to_intel_connector(connector); - struct drm_display_mode *mode; - - DRM_DEBUG_KMS("\n"); - - if (!intel_connector->panel.fixed_mode) { - DRM_DEBUG_KMS("no fixed mode\n"); - return 0; - } - - mode = drm_mode_duplicate(connector->dev, - intel_connector->panel.fixed_mode); - if (!mode) { - DRM_DEBUG_KMS("drm_mode_duplicate failed\n"); - return 0; - } - - drm_mode_probed_add(connector, mode); - return 1; -} - static void intel_dsi_encoder_destroy(struct drm_encoder *encoder) { struct intel_dsi *intel_dsi = enc_to_intel_dsi(encoder); -- 2.30.2
