Subject: [PATCH] arm64: dts: walnutpi: keep AXP313A DLDO1 at boot voltage
|
|
|
|
The WalnutPi U-Boot board description keeps DLDO1 enabled at 3.3V for
|
|
VCC-IO. Describe that rail as always-on after switching the Linux PMIC
|
|
binding to AXP313A so regulator cleanup cannot disable it as unused.
