Subject: [PATCH v1] arm64: dts: k3-am625-verdin: enable Verdin UART2
Date: Tue, 21 Nov 2023 17:04:36 +0100 [thread overview]
Message-ID: <20231121160436.1032364-1-parth105105@gmail.com> (raw)
From: Parth Pancholi <parth.pancholi@toradex.com>
Enable UART2 for AM62 based SOM's Verdin carrier boards Dahlia,
Development and Yavia.
Earlier Verdin UART2 was reserved by R5 DM firmware which can be now
configured using boardcfg during U-boot compilation in the latest TI
SDKs. In a default config, no one writes to this UART.
