From 2480c018ea2ae53879725b79beba4a9e38ce5e82 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 3 Jun 2016 20:10:40 +0200 Subject: [PATCH] ARM: dts: sun5i-a10s-wobo-i5: Enable ldo4 too It seems that the wifi chip is powered by both ldo3 and ldo4 tied together and that using only one results in the wifi-chip dropping of the USB bus sometimes. Ideally we would have a proper way of modelling this (this is being worked on), but currently we do not. This is not an issue since we need to keep these regulators always-on anyways, due to these boards crashing when ldo3/4 get turned back on after having been turned off.
