Hi all,
This patch series adds the cpu-supply properties to the a57_0 nodes on
the Salvator-X(S) and ULCB development boards, so Dynamic Voltage and
Frequency Scaling (DVFS) can change the CPU core voltages.
This is a prerequisite for enabling CPU boost modes.
To be queued in renesas-devel for 5.13.
