+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.
+
