From: Stefan Agner Date: Wed, 29 Mar 2017 23:21:11 +0000 (-0700) Subject: ARM: dts: imx7-colibri: allow to disable Ethernet rail X-Git-Tag: v4.14-rc1~952^2~13^2~7 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8f4c8bd9561cafd10d3a885900213ce4a544edbe;p=platform%2Fkernel%2Flinux-rpi.git ARM: dts: imx7-colibri: allow to disable Ethernet rail The regulator-always-on property on the Ethernet rail prevents Linux from disabling the rail when Ethernet is shut down (suspend or simply link down). With this change the regulator framework will disable the rail when the Ethernet PHY is not used, saving power especially on carrier board not using Ethernet.
