The i2c_bus_num can be used to probe needed information from the eeprom,
like EDID from DVI monitors.

2012-08-17T08:18:10+00:00

Force is available from (*detect) at drm_connector_funcs, and can be used
by the driver to avoid expensive, destructive operations during automated
probing.

2012-08-17T08:18:09+00:00

The API should return whether the device is detected, and if applicable
whether the cable is plugged in. For non-hot-plug devices, it simply
means "is the display/panel present". For hot-plug devices it means "is
the cable plugged in".

Subject: [PATCH 02/21] Subject: [PATCH 01/19] OMAP4: DSS: add generic notifier mechanism

2012-08-17T08:18:09+00:00

A callback can be registered by the dssdev client in order to be
notified of resolution changes, for example an external monitor
that is hot-plugged.

Multiple clients can now register for notification from one
dssdev, and the notification mechanism can be extended in the
future to add other events.

This is a port of Rob Clark's  original patch.

OMAPDSS: HDMI: PHY burnout fix

2012-03-26T09:26:56+00:00

BugLink: http://bugs.launchpad.net/bugs/954576

commit c49d005b6cc8491fad5b24f82805be2d6bcbd3dd upstream.

A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.

This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.

The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.

The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.
