    drm/i915: (re)init HPD interrupt storm statistics · 821450c6
    Egbert Eich 提交于
    When an encoder is shared on several connectors there is only
    one hotplug line, thus this line needs to be shared among these
    connectors.
    If HPD detect only works reliably on a subset of those connectors,
    we want to poll the others. Thus we need to make sure that storm
    detection doesn't mess up the settings for those connectors.
    Therefore we store the settings in the intel_connector struct and
    restore them from there.
    If nothing is set but the encoder has a hpd_pin set we assume this
    connector is hotplug capable.
    On init/reset we make sure the polled state of the connectors
    is (re)set to the default value, the HPD interrupts are marked
    enabled.
