Saravana Kannan d5f13bbb51 drivers: bus: simple-pm-bus: Add support for probing simple bus only devices ... commit 98e96cf80045a383fcc47c58dd4e87b3ae587b3e upstream. fw_devlink could end up creating device links for bus only devices. However, bus only devices don't get probed and can block probe() or sync_state() [1] call backs of other devices. To avoid this, probe these devices using the simple-pm-bus driver. However, there are instances of devices that are not simple buses (they get probed by their specific drivers) that also list the "simple-bus" (or other bus only compatible strings) in their compatible property to automatically populate their child devices. We still want these devices to get probed by their specific drivers. So, we make sure this driver only probes devices that are only buses.
