在 ARM、RISC-V、PowerPC 以及大量国产化 SoC 平台中,Device Tree(设备树)已经成为 Linux BSP、驱动适配和板级 bring-up 的核心基础设施。很多系统研发工程师日常会改 DTS、排查 probe 失败、修 GPIO 和中断,但如果只停留在“会改节点”的层面,遇到 deferred probe、overlay ...
As a standard feature of the Linux kernel, device tree overlays (DTOs) allow for easy enabling and configuration of features and drivers, such as those contained within the standard firmware of a ...
V4L2 driver development for MIPI CSI-2 sensors demands accurate device tree configuration, sensor subdevice registration, and ...
Editor's Note: Embedded Linux has consistently ranked among the top operating systems used in embedded system design. With the rapid growth in interest in the Internet of Things (IoT), the ability of ...
In the last Driving Me Nuts column [see LJ, June 2003], we introduced the kernel driver model framework with an explanation of how the generic bus and driver and device code works. The i2c core was ...
