Subject: [PATCH 2/3] arm64: dts: qcom: lemans: Add Draco EVK SoM platform
Date: Mon, 19 Oct 2026 15:57:33 +0530 [thread overview]
Message-ID: <20261019-lemans-draco-final-changes-bringup-v1-2-dcabe94f1074@oss.qualcomm.com> (raw)
In-Reply-To: <20261019-lemans-draco-final-changes-bringup-v1-0-dcabe94f1074@oss.qualcomm.com>
Introduce the device tree for the SA8775P/QCS9100-based LeMans Draco
EVK SoM. The LeMans Draco SoM is a compact compute module integrating
the SA8775P SoC, three PMM8654AU PMICs, and essential connectivity,
designed to mount on carrier boards.
The initial SoM device tree includes basic support for:
- RPMH regulators for three PMM8654AU PMICs
- QUP firmware paths (qupv3_id_0/1/2)
- Remoteproc instances (ADSP, CDSP0/1, GPDSP0/1) with firmware paths
- Debug UART (uart10) and board clocks
- UFS storage
- USB 0, USB 1 (host mode) and USB 2 with HSPHY and QMP PHY supplies
- GPU (Adreno 663) with ZAP shader firmware
- Video processing unit (iris)
