Subject: [GIT PULL] DeviceTree updates for 3.16
Linus,
Please pull DT updates for 3.16. This cycle is a bit bigger than
normal with a bunch of FDT clean-ups and the addition of early console
initialization from DT. The earlycon support has a dependency on the
tty tree which is already in your tree.
There's one trivial conflict with your tree in
arch/arm/mach-vexpress/platsmp.c and the hunk should be removed. In my
merge, the auto conflict resolution got the merge in
of_update_property wrong incorrectly applying both hunks. The
incorrect merge commit looks like this:
diff --cc drivers/of/base.c
index 32e969d,567e6e1..779faaa
--- a/drivers/of/base.c
+++ b/drivers/of/base.c
@@@ -1828,15 -1900,16 +1900,20 @@@ int of_update_property(struct device_no
next = &(*next)->next;
}
raw_spin_unlock_irqrestore(&devtree_lock, flags);
- if (!found)
- return -ENODEV;
+ if (rc)
+ return rc;
+
+ /* At early boot, bail out and defer setup to of_init() */
+ if (!of_kset)
+ return 0;
+ /* At early boot, bail out and defer setup to of_init() */
+ if (!of_kset)
+ return found ? 0 : -ENODEV;

/* Update the sysfs attribute */
- sysfs_remove_bin_file(&np->kobj, &oldprop->attr);
+ if (oldprop)
+ sysfs_remove_bin_file(&np->kobj, &oldprop->attr);
__of_add_property_sysfs(np, newprop);
return 0;
The correct resolution is keeping the first "if (!of_kset)" and
dropping the 2nd one as found is no longer present. I'm not sure why,
but this error doesn't show up in linux-next.

of: handle NULL node in next_child iterators (2014-06-04 04:46:01 -0500)
----------------------------------------------------------------
DeviceTree for 3.16:
- Another round of clean-up of FDT related code in architecture code.
This removes knowledge of internal FDT details from most architectures
except powerpc.
- Conversion of kernel's custom FDT parsing code to use libfdt.
- DT based initialization for generic serial earlycon. The introduction
of generic serial earlycon support went in thru tty tree.
- Improve the platform device naming for DT probed devices to ensure
unique naming and use parent names instead of a global index.
- Fix a race condition in of_update_property.
- Unify the various linker section OF match tables and fix several
function prototype errors.
- Update platform_get_irq_byname to work in deferred probe cases.
- 2 binding doc updates
