Subject: [PATCH] BCM270X_DT: Don't generate "linux,phandle" props
|
2016-04-24 11:03:39 +00:00
|
|
|
|
|
|
|
|
The EPAPR standard says to use "phandle" properties to store phandles,
|
|
|
|
|
rather than the deprecated "linux,phandle" version. By default, dtc
|
|
|
|
|
generates both, but adding "-H epapr" causes it to only generate
|
|
|
|
|
"phandle"s, saving some space and clutter.
