Subject: [PATCH 3/9] arm64: dts: allwinner: pinebook: Remove unused AXP803 regulators
Date: Sun, 19 Jan 2020 10:30:58 -0600	[thread overview]
Message-ID: <20200119163104.13274-3-samuel@sholland.org> (raw)
In-Reply-To: <20200119163104.13274-1-samuel@sholland.org>

The Pinebook does not use the CSI bus on the A64. In fact it does not
use GPIO port E for anything at all. Thus the following regulators are
not used and do not need voltages set:

 - ALDO1: Connected to VCC-PE only
 - DLDO3: Not connected
 - ELDO3: Not connected
