| 2023-03-10 | driver core: Make state_synced device attribute writeable | Saravana Kannan | 1 | -0/+5 | |
| If the file is written to and sync_state() hasn't been called for the device yet, then call sync_state() for the device independent of the state of its consumers. This is useful for supplier devices that have one or more consumers that don't have a driver but the consumers are in a state that don't use the resources supplied by the supplier device. This gives finer grained control than using the fw_devlink.sync_state=timeout kernel commandline parameter.

| 2020-07-10 | driver core: Add state_synced sysfs file for devices that support it | Saravana Kannan | 1 | -0/+24 | |
| This can be used to check if a device supports sync_state() callbacks and therefore keeps resources left on by the bootloader enabled till all its consumers have probed. This can also be used to check if sync_state() has been called for a device or whether it is still trying to keep resources enabled because they were left enabled by the bootloader and all its consumers haven't probed yet.
