I've introduced an 'aggregate' bus that we put the aggregate device onto and then we probe the aggregate device once all the components are probed and call component_add(). The probe/remove hooks are where the bind/unbind calls go, and then a shutdown hook is added that can be used to shutdown the drm display pipeline at the right time. This works for me on my sc7180 board. I no longer get a warning from i2c at shutdown that we're trying to make an i2c transaction after the i2c bus has been shutdown. There's more work to do on the msm drm driver to extract component device resources like clks, regulators, etc. out of the component bind function into the driver probe but I wanted to move everything over now in other component drivers before tackling that problem. Tested-by tags would be appreciated, and Acked-by/Reviewed-by tags too. Per Daniel, I've resent this to collect Acks or Review tags from gregkh and once Greg is happy with the driver core bits it can be merged through drm-misc tree via dianders (both are on the To line). One last thing, I suspect I'll have to send this once again after the merge window because something is probably in linux-next that conflicts with some driver patch. I'll do that in about two weeks.
