From 77404a6a2889891a390428edf5f68847e307cd22 Mon Sep 17 00:00:00 2001 From: Jianqun Xu Date: Tue, 26 Mar 2019 09:45:45 +0800 Subject: [PATCH] arm64: dts: rockchip: rk3308b-evb-v10 modify vccio_flash to 3.3v The power supply for vccio_flash is depends on GPIO0_A4(pin R3 on SoCs), if GPIO0_A4 input high, vccio_flash = 1.8v if GPIO0_A4 input low, vccio_flash = 3.3v Reference to rk_board_init() in arch/arm/mach-rockchip/rk3308/rk3308.c, it has configure vccio3 io-domain, so here needn't to do more. BUT lack of vccio3 will make regulator summary hard to read, it's better to configure vccio3 = <&vccio_flash> after double check its voltage.
