[RFC 0/2] staging: ion: of_ion_device_get

From: Moritz Fischer
Date: Tue Mar 22 2016 - 18:34:30 EST

Hi all,

probably I'm doing this all wrong. I'm playing around with a bunch of accelerators
and I need to share buffers between them. I have my heaps implemented as a
platform device and from what I understand I'll need a reference to the
struct ion_device in each of them.
I couldn't find a way to get to that via devicetree, though. I'll admit that hacking
up miscdevice is quite hacky, maybe I should add a foo_get_ion_device() to my
heap implementing platform device?
If someone can explain me how to correctly do that with what we currently have,
even better.



Moritz Fischer (2):
misc: Add of_get_misc get a reference from devicetree
staging: android: ion: Add of_ion_device_get function
