   4 Subject: [PATCH 2/7] riscv: sifive: unmatched: update regulators values
   5
   6 These are the regulators values from the schematics for Rev3{A,B} boards.
   7
   8 Note this is not fully correct as bcore1/bcore2 and bmem/bio are merged, but
   9 it's only supported in v5.15 kernel. See:

  11 541ee8f640327f951e7039278057827322231ab0 ("regulator: da9063: Add support for
  12 full-current mode.")
  13
  14 This will be changed for v5.15 kernel based on the patch above.
