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