Subject: [PATCH 5/5] arm64: dts: rockchip: Add rock-5a board
Date:   Tue,  8 Nov 2022 18:15:00 +0100
Message-Id: <20221108171500.99599-6-sebastian.reichel@collabora.com>
In-Reply-To: <20221108171500.99599-1-sebastian.reichel@collabora.com>

Add board file for the RK3588s Rock 5A board. While the hardware
offers plenty of peripherals and connectivity this basic implementation
just handles things required to access eMMC, UART and Ethernet (i.e.
enough to successfully boot Linux).
