From eacd9c431ac6fcb975103899c67575251074179c Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Mon, 30 Jul 2018 13:31:30 +0100 Subject: [PATCH] arm64: dts: allwinner: a64: Orange Pi Win: Adjust CSI power rails The Orange Pi Win board uses the AXP's ALDO1 power rail to drive the VCC-CSI line, which, according to the schematic, needs to be set to 2.8V. Also the ELDO3 power rail is connected to the CSI, with somewhat unclear voltage requirements. Add this regulator and allow the voltage to be set between 1.5V and 1.8V, which are the voltages mentioned in the schematic.
