Subject: [PATCH v4 2/2] arm64: dts: qcom: msm8953-lenovo-kuntao: Add initial device tree
Date: Fri, 31 Oct 2025 19:21:21 +0530 [thread overview]
Message-ID: <20251031135506.214025-2-raihan1999ahamed@gmail.com> (raw)
In-Reply-To: <20251031135506.214025-1-raihan1999ahamed@gmail.com>
Lenovo P2 is a handset using the MSM8953 SoC released in 2016
Add a device tree with initial support for:
- Enable accelerometer sensor
- Enable pinctrl for GPIO keys
- Enable gpu and add gpu_zap_shader
- GPIO keys
- SDHCI (internal and external storage)
- USB Device Mode
- WCNSS (WiFi/BT)
- Regulators

version 4
- rebased on linux-next
- enabled accelerometer sensor
- enabled gpu and add gpu_zap_shader
- add homescreen and one-key-low-power gpio-keys
- enabled pinctrl for gpio-keys
- removed explicily added tag
version 3
- sorry for explicitly adding tags
