| Subject: arm64: dts: allwinner: a64: NanoPi-A64: Fix DCDC1 voltage |
| |
| From: Andre Przywara <andre.przywara@arm.com> |
| |
| [ Upstream commit 480f58cdbe392d4387a2193b6131a277e0111dd0 ] |
| |
| According to the NanoPi-A64 schematics, DCDC1 is connected to a voltage |
| rail named "VDD_SYS_3.3V". All users seem to expect 3.3V here: the |
| Ethernet PHY, the uSD card slot, the camera interface and the GPIO pins |
| on the headers. |
| Fix up the voltage on the regulator to lift it up to 3.3V. |
