this is a 2019 thing now, see an initial announcement from Rob from a
year ago: [0]

the new yaml schemas allow validation of the actual .dts
this can be used for verifying that the example in the dt-bindings is
correct, as well as for verifying the actual .dts file (so they match
the actual dt-binding)
(Rob's old mail - linked above - still has these two on the TODO list,
nowadays this works fine)

Neil is working towards full yaml schema based validation for all IP
blocks used on Amlogic SoCs.
with this patch we get a bit closer to that goal
