The pinctrl-msm8953 driver governs the 142 General Purpose Input/Output (GPIO) pins on the chip. High-quality implementation requires exact pin muxing configurations within the device tree. Incorrect configurations can lead to high power leakage or hardware instability when peripherals like SD cards, Wi-Fi chips, or touchscreens try to initialize.

The Qualcomm Snapdragon 625—internally known by its chipset model number —is a legendary piece of silicon. Released in 2016, it became the workhorse of the mid-range Android market for years, appearing in devices like the Xiaomi Redmi Note 4X, Moto G5 Plus, and countless IoT devices [1]. While its raw processing power is surpassed by today's standards, its efficiency and widespread adoption mean it remains active in many embedded projects, industrial systems, and custom ROM scenarios. While its raw processing power is surpassed by
