Are you planning to for a specific MSM8953 device, or Generic MSM8953 (qcom-msm8953) - postmarketOS Wiki
The MSM8953 relies on standard Qualcomm qcom drivers in the Linux kernel: drivers/gpu/drm/msm : Adreno GPU driver. drivers/phy/qualcomm : PHY drivers for USB and UFS. sound/soc/qcom : ALSA audio drivers. 3.2 Device Tree (DTS) - The Critical Component
The ARMv8-A architecture, which introduces the 64-bit instruction set (AArch64), is the bedrock of modern Qualcomm SoCs. The arm64 architecture is the central hub for drivers, primarily defined within the . msm8953 for arm64 driver
Mainline support involves defining hardware in .dts files, such as msm8953-xiaomi-mido.dts for the Redmi Note 4.
. Driving this hardware requires distinct approaches depending on whether you are working with official vendor (downstream) kernels or modern open-source (mainline) Linux. Key Driver Categories for MSM8953 Are you planning to for a specific MSM8953
