Hi all,
This RFC series is a follow-up to my previous RFC patch [1].
This time the series includes one possible of_notifier implementation for people to understand the need of radix_tree (or similar mechanism) as suggested by Fabio.
However, if you wish to try this on, you'll need a tree with patches from the renesas-drivers tree to have configfs support [2].
To ease that process, my testing tree was pushed to github [3] which is based on today's linux-next tree.
Finally, the device tree overlay was also pushed to github [4]. This last repo also contains what is needed to build the overlay out of tree plus some helper script to load the overlay.
With this tree and overlay, two spidev devices can be added from user-space with the proper pinctrl being applied.
The patches of this series include some comment on their purpose / implementation.
Regards, Gary
