It stayed because we -don't have the Pi3's HPD line exposed to Linux, so this was the only -way to bring up graphics on it. - -However, with the DSI panel support now present, users want to be able -to run DSI-only systems, and forcing HDMI on is interfering with -default screen configurations. Work around the Pi3's missing HPD by -probing the DDC on I2C and see if it's present at all. - -Signed-off-by: Eric Anholt <eric@anholt.net> ---- - drivers/gpu/drm/vc4/vc4_hdmi.c | 5 +++-- - 1 file changed, 3 insertions(+), 2 deletions(-) - ---- a/drivers/gpu/drm/vc4/vc4_hdmi.c -+++ b/drivers/gpu/drm/vc4/vc4_hdmi.c -@@ -166,8 +166,6 @@ vc4_hdmi_connector_detect(struct drm_con - struct drm_device *dev = connector->dev; - struct vc4_dev *vc4 = to_vc4_dev(dev); - -- return connector_status_connected; -- - if (vc4->hdmi->hpd_gpio) { - if (gpio_get_value_cansleep(vc4->hdmi->hpd_gpio) ^ - vc4->hdmi->hpd_active_low) -@@ -176,6 +174,9 @@ vc4_hdmi_connector_detect(struct drm_con - return connector_status_disconnected; - } - -+ if (drm_probe_ddc(vc4->hdmi->ddc)) -+ return connector_status_connected; -+ - if (HDMI_READ(VC4_HDMI_HOTPLUG) & VC4_HDMI_HOTPLUG_CONNECTED) - return connector_status_connected; - else |
