PM / OPP: Remove 'operating-points-names' binding
These aren't used until now by any DT files and wouldn't be used now as we have a better scheme in place now, i.e. opp-property-<name> properties. Remove the (useless) binding without breaking ABI.

@ -45,21 +45,10 @@ Devices supporting OPPs must set their "operating-points-v2" property with
|
||||
phandle to a OPP table in their DT node. The OPP core will use this phandle to
|
||||
find the operating points for the device.
|
||||
|
||||
Devices may want to choose OPP tables at runtime and so can provide a list of
|
||||
phandles here. But only *one* of them should be chosen at runtime. This must be
|
||||
accompanied by a corresponding "operating-points-names" property, to uniquely
|
||||
identify the OPP tables.
|
||||
|
||||
If required, this can be extended for SoC vendor specfic bindings. Such bindings
|
||||
should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt
|
||||
and should have a compatible description like: "operating-points-v2-<vendor>".
|
||||
|
||||
Optional properties:
|
||||
- operating-points-names: Names of OPP tables (required if multiple OPP
|
||||
tables are present), to uniquely identify them. The same list must be present
|
||||
for all the CPUs which are sharing clock/voltage rails and hence the OPP
|
||||
tables.
