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_bios.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'drivers/gpu/drm/i915/intel_bios.h') diff --git a/drivers/gpu/drm/i915/intel_bios.h b/drivers/gpu/drm/i915/intel_bios.h index af0b47652752..f7ad6a585129 100644 --- a/drivers/gpu/drm/i915/intel_bios.h +++ b/drivers/gpu/drm/i915/intel_bios.h @@ -778,6 +778,13 @@ int intel_parse_bios(struct drm_device *dev); #define MIPI_DSI_UNDEFINED_PANEL_ID 0 #define MIPI_DSI_GENERIC_PANEL_ID 1 +/* + * PMIC vs SoC Backlight support specified in pwm_blc + * field in mipi_config block below. +*/ +#define PPS_BLC_PMIC 0 +#define PPS_BLC_SOC 1 + struct mipi_config { u16 panel_id; -- cgit v1.2.1
