From 9ecdf30cfee377b7a1e4c2de67f99e593bbfa24a Mon Sep 17 00:00:00 2001 From: Keerthy Date: Thu, 12 Oct 2017 10:18:45 +0530 Subject: [PATCH] board: ti: dra71x-evm: Hook LDO1 of LP8733 to EN_PIN All regulators are hooked to EN_Pin at reset so that EN Pin controls their state. Hook the LDO1 regulator to EN pin which at reset is not hooked. This applies only to LP8733.
