DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.

This is common to all CPUs in the system so it lives
|

under the "cpus" node.

brcm,bmips-cbr-reg:
|
|
description: Reference address of the CBR.
|
|
Some SoC suffer from a BUG where CBR(Core Base Register)
|
|
address might be badly or never initialized by the Bootloader
|
|
or reading it from co-processor registers, if the system boots
|
|
from secondary CPU, results in invalid address.
|
|
The CBR address is always the same on the SoC hence it
|
|
can be provided in DT to handle these broken case.
