From 657819ff477dd73cd71075609698aa57ba098d8c Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/7] riscv: sifive: unmatched: update regulators values
These are the regulators values from the schematics for Rev3{A,B} boards.
Note this is not fully correct as bcore1/bcore2 and bmem/bio are merged, but
it's only supported in v5.15 kernel. See:
541ee8f640327f951e7039278057827322231ab0 ("regulator: da9063: Add support for
full-current mode.")
This will be changed for v5.15 kernel based on the patch above.
