Subject: arm64: dts: allwinner: a523: Mark dual-phased regulators
|
|
|
|
The X-Powers AXP323 PMIC on the boards with a SoC from the Allwinner
|
|
A523 family typically uses DCDC1 and DCDC2 in a dual-phase setup to
|
|
supply the "big" CPU cluster. For some reason this dual-phase
|
|
configuration is not the PMIC's reset default, but needs to be actively
|
|
programmed at runtime.
|
|
|
|
Add the newly introduced x-powers,polyphased property in the board DTs,
|
|
to mark this connection and let drivers program the dual-phase setup.
|
|
