What is connected to those DP lanes? If they are routed directly to the
DisplayPort connectors, please add corresponding devices (see
dp-connector).
We are defining the functionality of gpio101 and gpio102 as "edp0_hot"
and "edp1_hot"
respectively. This ensures that the hot plug will be directly routed via
the display interrupt
line "mdss0" to the display port driver and no external dependencies on
dp-connector is
necessary.
Please describe the hardware, not the driver necessities.
If the board has a DP connector, please add the node. E.g. it allows
one to specify the label and the type used by the connector.
Also could you please fix your email client so that you don't have
strange/unnecessary line wraps and empty lines?
Addition of DP connector node with the hpd-gpio property does not allow
hpd to be detected since the gpio
101/102 have the "edp0_hot" as function. If the hpd-gpio property is
removed from the DP connector node,
the probe of DP connector will fail.
