If you are a developer, focus your efforts on:
Several device trees (board-specific DTS files) for MSM8953-based phones have been contributed to the kernel, providing excellent real-world configuration examples:
From your device’s stock ROM (Android 9 typically), extract /vendor partition. Then separate:
#include <linux/module.h> #include <linux/init.h> msm8953 for arm64 driver
The (Mobile Station Modem 8953), commercially known as the Qualcomm Snapdragon 625, and its slightly faster sibling, the Snapdragon 626, is one of the most prolific mobile system-on-chips (SoCs) ever produced. Released in 2016, it has powered hundreds of devices—from the Xiaomi Redmi Note 4 and Moto Z Play to the Samsung Galaxy A series and countless IoT devices.
Realistically, a fully functional mainline Linux ARM64 desktop on MSM8953 is – but the progress is tangible.
The you are developing on (e.g., legacy downstream 3.18/4.9, or modern mainline 6.x). If you are a developer, focus your efforts
provide work-in-progress patches for running standard Linux kernels on Snapdragon 625 devices. PostmarketOS Drivers : This project maintains Snapdragon 625 driver status
Qualcomm audio is notorious for being convoluted, routing audio through various digital signal processors (DSPs) and codecs (such as the wsa881x ).
Perhaps the most fascinating aspect of the MSM8953 driver history is its role in the custom ROM community. Because the Snapdragon 625 was used in over a hundred different smartphone models, it became a prime target for developers porting newer Linux kernels and Android versions to older hardware.

Translates the physical address defined in the device tree into a virtual address space that the ARM64 MMU can safely read and write. 4. Cross-Compiling for the ARM64 Architecture
Developers look for "msm8953 for arm64 driver" solutions when upgrading custom hardware to newer Linux kernels (e.g., Linux 6.x). This migration presents three major obstacles:
: Interfacing SPI, I2C, or UART hardware lines.
