If you are looking to build a custom ROM or bring up a new Linux distribution on an older Qualcomm device, identifying the correct DTS and using the latest mainline kernel drivers is the best starting point.

The Linux kernel is the core of any ARM64 system. For MSM8953, most critical drivers are now present in the mainline kernel, with active development occurring for the remaining components. The msm8953-mainline community fork, which is very close to the mainline, serves as the central hub for this development. The table below summarizes the current support status for key drivers:
/ compatible = "qcom,msm8953"; soc compatible = "qcom,msm8953-soc"; reg = <0x0 0x...>; clocks = <&gcc ...>; ; kgsl@... compatible = "qcom,kgsl"; reg = <...>; interrupt-parent = <&msm_gic>; ; mdss@... /* display controller */ ; mdss_panel@0 compatible = "manufacturer,panel-model"; /* timing */ ; ; msm8953 for arm64 driver

Many subsystems (Modem, GPU, Wi-Fi) require proprietary firmware "blobs" to function, which must be loaded by the kernel at runtime.

Understanding the MSM8953 for ARM64 Driver Architecture The , popularly known as the Qualcomm Snapdragon 625 , remains a cornerstone of the mid-range ARM64 ecosystem. For developers working on Linux mainlining or Android kernel development, understanding how to configure and build drivers for this 64-bit octa-core processor is essential for hardware enablement. 1.

You're interested in a paper on the MSM8953 driver for ARM64 architecture!
The (commonly known as the Snapdragon 625) is a widely adopted octa-core ARMv8-A system-on-chip, built on a power-efficient 14nm FinFET process. Released in 2016, it has powered a vast fleet of smartphones, including the Fairphone 3, Lenovo P2, and Xiaomi Redmi Note 4, as well as being used in numerous Internet of Things (IoT) and industrial boards.
