To do that, a pol_flags field was added to drm_display_mode. Signed-off-by: Denis Carikli --- ChangeLog v10->v11: - Since the imx-drm won't be able to retrive its regulators from the device tree when using display-timings nodes, and that I was told that the drm simple-panel driver already supported that, I then, instead, added what was lacking to make the eukrea displays work with the drm-simple-panel driver. That required a way to get back the display polarity informations from the imx-drm driver without affecting userspace. --- include/drm/drm_crtc.h | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/include/drm/drm_crtc.h b/include/drm/drm_crtc.h index f764654..61a4fe1 100644 --- a/include/drm/drm_crtc.h +++ b/include/drm/drm_crtc.h @@ -131,6 +131,13 @@ enum drm_mode_status { #define DRM_MODE_FLAG_3D_MAX DRM_MODE_FLAG_3D_SIDE_BY_SIDE_HALF +#define DRM_MODE_FLAG_POL_PIXDATA_NEGEDGE BIT(1) +#define DRM_MODE_FLAG_POL_PIXDATA_POSEDGE BIT(2) +#define DRM_MODE_FLAG_POL_PIXDATA_PRESERVE BIT(3) +#define DRM_MODE_FLAG_POL_DE_NEGEDGE BIT(4) +#define DRM_MODE_FLAG_POL_DE_POSEDGE BIT(5) +#define DRM_MODE_FLAG_POL_DE_PRESERVE BIT(6) + struct drm_display_mode { /* Header */ struct list_head head; @@ -183,6 +190,7 @@ struct drm_display_mode { int vrefresh; /* in Hz */ int hsync; /* in kHz */ enum hdmi_picture_aspect picture_aspect_ratio; + unsigned int pol_flags; }; static inline bool drm_mode_is_stereo(const struct drm_display_mode *mode)
