Subject: [PATCH] dts: fdto: the fdt is damaged in booting process [1/1]

PD#SWPL-2960

Problem:
If the overlay dts refers to a node which does not exist in the base
device tree, the final fdt will be in a damaged state after doing fdt
overlay

Solution:
Use the standard overlay dts syntax to note node to be applied instead
of the google recommended one

Verify:
Locally on P230
