Subject: [PATCH V3] ARM: dts: da850-evm: use phandles to extend nodes
Many node labels in the device tree (like serial0, serial1, etc) are being
redefined, so let's modernize the device tree by using phandles to
extend the existing nodes. This helps reduce the whitespace.
Signed-off-by: Adam Ford <aford173@...il.com>
---
V3: Rebase against 4.18/dt and fix subject.
V2: Rename subject per feedback from Sekhar.
Extend notes from tps6507x
Add empty line after each node
