- Added Tested-by: tags from Laurent and Grygorii.
New Patch 17:
- New patch to delete useless input to add_links()
Saravana Kannan (17):
Revert "driver core: Avoid deferred probe due to
fw_devlink_pause/resume()"
Revert "driver core: Rename dev_links_info.defer_syn

A bigger question I had is why we need to grab device_pm_lock() around
device_link_del() in the first place. I understand the need to

Thanks for pointing it out Frank. Also, might want to avoid top
posting in the future.

Hi Mark,
It *might* be easier if you jump to the bottom and read the reasoning
for the current design. The stuff in between is just me trying to
clarify some misunderstandings.

Add support for creating device links out of the following DT bindings:
- interrupts-extended
- nvmem-cells
- phys
- wakeup-parent

The devlink device name is of the form "supplier:consumer". But ":" is
fairly common in device names and makes it visually hard to distinguish
supplier and consumer. So, replace it with "--" to make it easier.

to parse all pinctrl-* properties and checking for pinctrl-%d is
unnecessarily complicated. So, just add support for pinctrl-[0-8] for
now. In the unlikely event we ever exceed pinctrl-8, we can come back
and improve this.
