b8b52471e8 drm/exynos: dp: support hotplug detection via GPIO
Certain bridge chips use a GPIO to indicate the cable status instead
of the I_DP_HPD pin.  This adds an optional device-tree property,
"samsung,hpd-gpio", to the exynos-dp controller which indicates that
the specified GPIO should be used for hotplug detection.
The GPIO is then set up as an edge-triggered interrupt where the
rising edge indicates hotplug-in and the falling edge indicates hotplug-out.

the dp driver. This will allow for tighter integration of the dp driver
into the exynos drm driver.
