From mboxrd@z Thu Jan 1 00:00:00 1970 From: dev@lynxeye.de (Lucas Stach) Date: Sat, 8 Apr 2017 16:36:07 +0200 Subject: [RFC PATCH 7/7] ARM: dts: imx6*-hummingboard2: rework regulators In-Reply-To: <20170408143607.15928-1-dev@lynxeye.de> References: <20170408143607.15928-1-dev@lynxeye.de> Message-ID: <20170408143607.15928-8-dev@lynxeye.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Name the regulators according to the voltage rails they are feeding in the schematic. The USB 2-4 regulators are fixed regulators and are always on, as they are not a VBUS supply for a single USB host port on the i.MX6, but supply VBUS to ports behind a USB hub and there is currently no way to model this in mainline.
