Subject: [PATCH 07/10] rpi: Enable USB Power domain during startup
Date: Fri, 20 Dec 2019 15:32:29 +0100 [thread overview]
Message-ID: <20191220143232.28354-8-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20191220143232.28354-1-s.hauer@pengutronix.de>
Enable the USB Power domain during startup. The power domain is
abstracted as a regulator in barebox, but modelled as a power domain in
the device tree. Until this is sorted out just enable the power domain
or regulator in the board code.
