Subject: [PATCH v2 6/6] arm64: dts: qcom: Add initial support for Nord Ride Embedded board
Date: Fri, 4 Sep 2026 16:16:19 +0800 [thread overview]
Message-ID: <20260904081619.593602-7-shengchao.guo@oss.qualcomm.com> (raw)
In-Reply-To: <20260904081619.593602-1-shengchao.guo@oss.qualcomm.com>
From: Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>
Add the initial device tree for the Nord Ride Embedded board, the
non-SCMI variant of the SA8797P automotive Ride board.
Enable the debug UART, UFS storage, the ADSP and CDSP remote processors,
and describe the board regulators supplied by the on-board PMICs.
