The two main changes here are: * a bugfix to deal with DT paths which contain a common, which are perfectly valid and quite common. * support for the /chosen/stdout-path device tree property, which allows Xen to find a boot console without manual configuration if presented with a suitable device tree. Juno and Seattle both contain the node in the dt supplied with the upstream Linux kernel (not sure about their factory kernel), as do a bunch of non-virt capable arm devices, but with stdout-path support being added to Linux in v3.19-rc1 I expect that number will soon grow. I think "dt-uart: use ':' as default separator between path and options" should be a candidate for stable backport, and if it makes the backport easier I'd be inclined to take "dt-uart: Clarify log messages at init time" too. Ian.
