This is surely an important driver since almost all elder Samsung
mobiles use this kind of switch. So
Acked-by: Linus Walleij <linus.walleij@xxxxxxxxxx>

This driver I see is already sent to Greg for inclusion in the next kernel.
I just wonder if you guys are even aware of this driver for the same
hardware added by Donggeun Kim in 2011:
drivers/misc/fsa9480.c

That said I am all for pulling in this new driver because it is surely
better and supports device tree.

But can we please also send Greg a patch to delete the old driver
so we don't have two of them now?

The old driver have no in-tree users so it can be deleted without
side effects. Out-of-tree users can certainly adapt to the new
extcon driver.

If you want I can send a deletion patch for the misc driver?

Yours,
Linus Walleij
