From a05eb8b14a46fd194caf2ae2c01e3a3431daab3e Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Sat, 25 Jan 2020 09:01:40 +0100 Subject: arm: xea: dts: Add 'fec-3v3' regulator properties to prevent accidental disablement The 'enable-active-high' DTS property configures GPIO so it is active with HIGH state (by default it is low). The 'regulator-boot-on' property indicates that the regulator was enabled in the 'earlier' stage - i.e. bootloader/firmware. In the XEA case the 'fec-3v3' was configured (as a "wrapper" on GPIO0_0) in very early SPL code, so it shouldn't be modified at latter stages.
