From fc45e821990781c13dba10e3aef1c9f11af8af08 Mon Sep 17 00:00:00 2001 From: Shobhit Kumar Date: Fri, 26 Jun 2015 14:32:09 +0530 Subject: drm/i915: Use the CRC gpio for panel enable/disable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The CRC (Crystal Cove) PMIC, controls the panel enable and disable signals for BYT for dsi panels. This is indicated in the VBT fields. Use that to initialize and use GPIO based control for these signals. v2: Use the newer gpiod interface(Alexandre) v3: Remove the redundant checks and unused code (Ville) v4: Moved PWM vs SoC backlight #defines to intel_bios.h (Jani) CC: Samuel Ortiz Cc: Linus Walleij Cc: Alexandre Courbot Cc: Thierry Reding Acked-by: Linus Walleij Reviewed-by: Jani Nikula Tested-by: Ville Syrjälä Signed-off-by: Shobhit Kumar Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_dsi.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/gpu/drm/i915/intel_dsi.h') diff --git a/drivers/gpu/drm/i915/intel_dsi.h b/drivers/gpu/drm/i915/intel_dsi.h index 2784ac442368..42a68593e32a 100644 --- a/drivers/gpu/drm/i915/intel_dsi.h +++ b/drivers/gpu/drm/i915/intel_dsi.h @@ -42,6 +42,9 @@ struct intel_dsi { struct drm_panel *panel; struct intel_dsi_host *dsi_hosts[I915_MAX_PORTS]; + /* GPIO Desc for CRC based Panel control */ + struct gpio_desc *gpio_panel; + struct intel_connector *attached_connector; /* bit mask of ports being driven */ -- cgit v1.2.3-70-g09d2
