H A D | device.h | 05ef983e Mon Oct 28 17:00:22 CDT 2019 Saravana Kannan <saravanak@google.com> driver core: Add device link support for SYNC_STATE_ONLY flag
Parent devices might need to create "proxy" device links from themselves to supplier devices to make sure the supplier devices don't get a sync_state() before the child consumer devices get a chance to add device links to the supplier devices.
However, the parent device has no real dependency on the supplier device and probing, suspend/resume or runtime PM don't need to be affected by the supplier device. To capture these cases, create a SYNC_STATE_ONLY device link flag that only affects sync_state() behavior and doesn't affect probing, suspend/resume or runtime PM.
