Create the following Makefile alongside your custom driver source code ( msm8953_custom_mod.c ):
(MSM8953) is a legendary workhorse in the mobile world. Known for its incredible efficiency and widespread use in devices like the Xiaomi Redmi Note 4 and Motorola Moto G5 Plus, it remains a favorite for developers porting modern Linux distributions or custom Android kernels. If you are looking to dive into arm64 driver development msm8953 for arm64 driver
Operating this hardware in a pure 64-bit ARM environment (AArch64) requires a clean separation between proprietary firmware blobs and open-source Linux kernel drivers. 2. Kernel Initialization and Device Tree Topology
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc) Use code with caution. 6. Common Debugging Strategies This public link is valid for 7 days
: The drivers/clk/qcom/gcc-msm8953.c driver manages the internal phase-locked loops (PLLs) and dividers, distributing precise frequencies to the serial buses (SPI, I2C, UART), MMC storage, and USB controllers.
: Powered by the Adreno 506. Mainline architectures use the open-source freedreno framework via the msm driver block, requiring firmware blobs ( a506_zap.b00 , etc.) to initialize safety zones via the trustzone/hypervisor. 4. Mainline vs. Downstream Kernels Can’t copy the link right now
: Maps to the Top-Level Mode Multiplexer (TLMM), Qualcomm’s GPIO and interrupt controller.

Achieving stable performance requires a deep understanding of the MSM8953 ARM64 driver stack, its device tree structure, and the integration of open-source components like the msm DRM/KMS graphics subsystem. 1. Hardware Architecture Overview
