If anyone has any objections, please let me know. ------------------ From: Tony Lindgren [ Upstream commit 10492ee8ed9188d6d420e1f79b2b9bdbc0624e65 ] It currently only works if the parent bus uses "simple-bus". We currently try to probe children with non-existing compatible values. And we're missing .probe. I noticed this while testing devices configured to probe using ti-sysc interconnect target module driver. For that we also may want to rebind the driver, so let's remove __init and __exit.
