Subject: [PATCH 2/5] arm64: dts: qcom: sc8180x: Add Microsoft Surface Pro X
Date: Wed, 4 Nov 2026 04:04:33 -0300 [thread overview]
Message-ID: <20261104070441.74127-3-val@packett.cool> (raw)
In-Reply-To: <20261104070441.74127-1-val@packett.cool>
From: Maximilian Luz <luzmaximilian@gmail.com>
Introduce a device tree for the Surface Pro X tablet in all 3 variants
(SQ1 with cellular, SQ1 Wi-Fi only, SQ2 with cellular).
Currently working:
* Display, backlight (eDP panel)
* USB 2.0
* Wi-Fi and Bluetooth (WCN3998)
* NVMe on PCIe2
* Embedded controller (Surface SAM over UART)
* All remoteprocs (ADSP, CDSP, MPSS, SLPI)
* Volume and power buttons
