From 91a18a414185a2b937e2cc8bf0cc32de1863d11a Mon Sep 17 00:00:00 2001 From: Greg Hackmann Date: Wed, 6 Jan 2016 14:05:36 +0000 Subject: [PATCH] platform: goldfish: pipe: add devicetree bindings Add bindings so we don't need to rely on goldfish virtual bus for probing any more, which means we don't need ARM and MIPS goldfish board code for instantiating the bus. In the long term we would like to move towards replacing the Android pipe with virtio-vsock that is currently under development.
