From 0ca12c1ee43ca2decd438e0c0d0550c84fa122c5 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Wed, 18 Oct 2017 21:06:25 +0800 Subject: [PATCH] ARM: sun8i: r40: add 5V regulator for Banana Pi M2 Ultra On newer revisions of the Banana Pi M2 Ultra boards, the 5V power output (used by HDMI, SATA and USB) is controller via a GPIO. Add the regulator node for it. Older revisions just have the 5V power output always on, and the GPIO is reserved on these boards. So it won't affect the older revisions.
