Subject: [PATCH v1 1/4] ARM: rpi: convert board code to a driver
Date: Mon, 17 Jan 2022 13:04:57 +0100 [thread overview]
Message-ID: <20220117120500.3556703-1-o.rempel@pengutronix.de> (raw)
Convert board code to a driver model. This will prevent executing this
part of code on any other BCM2xxx based boards.
