From 11dcae189003f31a7457bf2338fb78957f6a4534 Mon Sep 17 00:00:00 2001 From: Andreas Kemnade Date: Thu, 10 Oct 2024 14:29:54 +0200 Subject: ARM: dts: omap: omap4-epson-embt2ws: define GPIO regulators To properly have things running after cold boot, define GPIO regulators. Naming is based on board file. In the vendor kernel they are enabled in a function called bt2ws_dcdc_init() if the system is not booted just to charge the battery.
