Subject: [PATCH] arm64: dts: allwinner: h616: enable DVFS for all boards
|
|
|
|
With the DT bindings now describing the format of the CPU OPP tables, we
|
|
can include the OPP table in each board's .dts file, and specify the CPU
|
|
power supply.
|
|
This allows to enable DVFS, and get up to 50% of performance benefit in
|
|
the highest OPP, or up to 60% power savings in the lowest OPP, compared
|
|
to the fixed 1GHz @ 1.0V OPP we are running in by default at the moment.
