Msm8953 For Arm64 Driver Exclusive Guide

If you are developing or porting a driver for this platform, the process generally follows these steps:

What specific (display, camera, sensor, audio) are you trying to control?

The MSM8953 leverages the Synopsys DWC3 USB controller. The mainline kernel driver is fully operational, primarily supporting USB Device Mode (gadget). This setup is commonly used for functions like ADB over USB or USB network tethering. msm8953 for arm64 driver

An ARM64 Linux driver for the MSM8953 is structured as a platform_driver . This model decouples the driver code from the specific hardware addresses, parsing them dynamically from the device tree shown above.

Any or unexpected device behaviors you are encountering. Share public link If you are developing or porting a driver

The MSM8953 uses a custom Qualcomm LPA (Low Power Audio) or SLIMbus layout with a WCD9335/WCD9340 codec.

If you are looking to understand or implement , this guide covers the architectural essentials, the role of the Device Tree, and the current state of mainline Linux support. Understanding the MSM8953 Architecture This setup is commonly used for functions like

If an ARM64 driver disables a vital system clock during initialization due to an improper reference count, the SoC will immediately trigger a hardware reset or lock up. Pinctrl and TLMM Driver

ARM64 drivers do not directly write to power management IC (PMIC) registers like the PM8953.
