From 37ad490bab09b7c218e37b570069cf188f2616e7 Mon Sep 17 00:00:00 2001 From: Nicholas Lowell Date: Mon, 19 Mar 2018 09:23:14 -0400 Subject: regulator: giving regulator controlling gpios a non-empty label when used through the devicetree. When the label is empty, it causes missing information and limits diagnostics for instances such as 'cat /sys/kernel/debug/gpio' Setting the label to the regulator supply_name will point to the device using the gpio(s).
