Subject: [PATCH 0/4] DT printf format specifiers

This resurrects an old patch[1] from Pantelis adding printf format 
specifiers for DT nodes. The previous versions didn't get applied after 
debate about the what character(s) to use. Grant suggested %pO for 
base kobject and %pOF for struct device_node. Everyone agreed, but no 
new version was posted.

I ended up re-writing the core implementation to be more inline with how 
other format specifiers are written which allowed removing #define code 
fragments. The other 3 patches convert the core DT code to use %pOF and 
prepare for changing device_node.full_name to stop storing the full path 
for every node.

My plan is to merge this series for v4.13 and post follow-up patches to 
convert all arches and subsystems to %pOF for v4.14. The full series is 
available here[2]. I tested this on QEMU running the DT unittests.

Pantelis Antoniou (1):
  of: Custom printk format specifier for device node

Rob Herring (3):
  of: use kbasename instead of open coding
  of: find_node_by_full_name rewrite to compare each level
  of: Convert to using %pOF instead of full_name
