Subject: [PATCH v3 1/6] ARM: rpi: convert board code to a driver
Date: Thu,  3 Feb 2022 11:45:47 +0100	[thread overview]
Message-ID: <20220203104552.3158202-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20220203104552.3158202-1-o.rempel@pengutronix.de>

Convert board code to a driver model. This will prevent executing this
part of code on any other BCM2xxx based boards.
