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.
