This isn't just an internal detail, +since xrandr actually exposes "VGA" as the output name. Define some +new enums so that vc4's DPI can have a more informative name. + +I considered other names for the connector as well. For VC4, the +Adafruit DPI kippah takes the 28 GPIO pins and routes them to a +standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely +identify an ordering of pins (apparently some other orderings exist), +doesn't explain things as well for the user (who, if anything, knows +their product is a DPI kippah/panel combo), and actually doesn't have +to exist (one could connect the 28 GPIOs directly to something else). +Simply "DPI" seems like a good compromise name to distinguish from the +HDMI, DSI, and TV connectors . + +Signed-off-by: Eric Anholt <eric@anholt.net> +Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> +(cherry picked from commit 0b27c02a7f1c697694f2ad6d6517e7dbf9ecfa39) +--- + drivers/gpu/drm/drm_crtc.c | 2 ++ + include/uapi/drm/drm_mode.h | 2 ++ + 2 files changed, 4 insertions(+) + +--- a/drivers/gpu/drm/drm_crtc.c ++++ b/drivers/gpu/drm/drm_crtc.c +@@ -168,6 +168,7 @@ static struct drm_conn_prop_enum_list dr + { DRM_MODE_CONNECTOR_eDP, "eDP" }, + { DRM_MODE_CONNECTOR_VIRTUAL, "Virtual" }, + { DRM_MODE_CONNECTOR_DSI, "DSI" }, ++ { DRM_MODE_CONNECTOR_DPI, "DPI" }, + }; + + static const struct drm_prop_enum_list drm_encoder_enum_list[] = { +@@ -179,6 +180,7 @@ static const struct drm_prop_enum_list d + { DRM_MODE_ENCODER_VIRTUAL, "Virtual" }, + { DRM_MODE_ENCODER_DSI, "DSI" }, + { DRM_MODE_ENCODER_DPMST, "DP MST" }, ++ { DRM_MODE_ENCODER_DPI, "DPI" }, + }; + + static const struct drm_prop_enum_list drm_subpixel_enum_list[] = { +--- a/include/uapi/drm/drm_mode.h ++++ b/include/uapi/drm/drm_mode.h +@@ -202,6 +202,7 @@ struct drm_mode_get_plane_res { + #define DRM_MODE_ENCODER_VIRTUAL 5 + #define DRM_MODE_ENCODER_DSI 6 + #define DRM_MODE_ENCODER_DPMST 7 ++#define DRM_MODE_ENCODER_DPI 8 + + struct drm_mode_get_encoder { + __u32 encoder_id; +@@ -241,6 +242,7 @@ struct drm_mode_get_encoder { + #define DRM_MODE_CONNECTOR_eDP 14 + #define DRM_MODE_CONNECTOR_VIRTUAL 15 + #define DRM_MODE_CONNECTOR_DSI 16 ++#define DRM_MODE_CONNECTOR_DPI 17 + + struct drm_mode_get_connector { + |
