   4 Subject: [PATCH] arm64: dts: allwinner: a64: olinuxino: Add bank supply
   5  regulators
   6
   7 Allwinner A64 SoC has separate supplies for PC, PD, PE, PG and PL. This
   8 patch adds regulators for them to the pinctrl node.
   9
  10 Exception is PL which is used by the RSB bus. To avoid circular
  11 dependencies, VCC-PL is omitted.
  12
  13 On boards with eMMC, VCC-PC is supplied by ELDO1, instead of DCDC1.
