[PATCH v8 5/9] drm/bridge: aux-hpd: let drivers pass IRQ_HPD events

[Luca Ceresoli]

> The DisplayPort standard defines a special kind of HPD events called
> IRQ_HPD. These events are used to notify DP Source about the events on
> the Sink side.
>
> Let users of aux-hpd, the UCSI and PMIC GLINK drivers pass the IRQ_HPD
> events to the DisplayPort drivers.
>
> The drm_aux_hpd_bridge_notify() is kept to ease merging of the series,
> preventing extra cross-tree merges. It will be removed once all
> drivers are converted. The drm_bridge_hpd_notify() function is kept for
> the drivers which only care about the connector status and will always
> pass DRM_CONNECTOR_NO_EXTRA_STATUS as the extra status.

Do you have a plan to later convert all drm_bridge_hpd_notify() to the new
_extra() variant, then remove drm_bridge_hpd_notify() and eventually rename
drm_bridge_hpd_notify_extra() to drm_bridge_hpd_notify()?
