[PATCH libdrm v3 0/5] xf86drm: Add USB, platform and host1x bus support

[Thierry Reding <thierry.reding@gmail.com>]

From: Thierry Reding <treding@nvidia.com>

This series enables support for USB, platform and host1x busses in the
drmDevice infrastructure. The goal is to make use of these in Mesa for PRIME
support (via the DRI_PRIME environment variable) for devices on one of these
busses.

Changes in v3:
- add cleanup patch to reuse sysfs_uevent_get() in existing code
- guard Linux-specific sysfs parsing code with #ifdef __linux__

Changes in v2:
- add USB, platform and host1x bus support to tests/drmdevice
- make sure not to overflow path names and device fullnames
- read compatible strings into platform/host1x device info

I've tested both platform and host1x bus support on Tegra and also verified
that there aren't any leaks by running tests/drmdevice through valgrind.

Since I don't have any UDL devices myself I'm adding the X.Org development
mailing list on Cc, as suggested by Emil Velikov, in the hopes that someone
with access to that hardware will be generous enough to give these a run.
