How is this driver registered?
Looks like it has device tree support. Is there another way?
Yes, only using device tree
Then how about using 'simple-mfd' and 'syscon'?
Then you can omit this driver completely.
The exception is to support for non device tree platform as well, but I have
tested only for ARM device tree platform.
Is that a reality though?
How else do you see this realistically being registered?
I understand that acpi related device table are not covered here, well I
don't have to platform to test so.
If you ask me to cover acpi related table, I can do but hard to test.
