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.

The IXP4xx AHB Queue Manager maintains queues as circular buffers in
|
|
an 8KB embedded SRAM along with hardware pointers. It is used by both
|
|
the XScale processor and the NPEs (Network Processing Units) in the
|
|
IXP4xx for accelerating queues, especially for networking. Clients pick
|
|
queues from the queue manager with foo-queue = <&qmgr N> where the
|
|
&qmgr is a phandle to the queue manager and N is the queue resource
|
|
number. The queue resources available and their specific purpose
|
|
on a certain IXP4xx system will vary.
