Subject: [PATCH 3/3] arm64: dts: ti: Add support for AM642 EVM
Date: Tue, 24 Nov 2020 23:20:04 -0600 [thread overview]
Message-ID: <20201125052004.17823-4-d-gerlach@ti.com> (raw)
In-Reply-To: <20201125052004.17823-1-d-gerlach@ti.com>
The AM642 EValuation Module (EVM) is a board that provides access to
various peripherals available on the AM642 SoC, such as PCIe, USB 2.0,
CPSW Ethernet, ADC, and more.
Introduce basic support for the AM642 EVM to enable minimal
ramdisk boot.
