[PATCH 2/7] ARM: dts: qcom: add common device tree for MSM8x26-based Lumia phones
From: Rayyan Ansari
Date: Fri Aug 11 2023 - 17:44:31 EST
Add a common device tree for Lumias based on the Qualcomm MSM8x26
family of chipsets.
Currently supports:
- Framebuffer
- Touchscreen
- Keys
- Regulators
- MMC
- USB
- UART
