Implementing GPIO LED Control Using the Linux Platform Bus
Driver Source Code
The following implementation utilizes the platform bus architecture to manage GPIO-based LEDs. It establihses a character device interface and parses device tree information during the probe phase.
#include <linux/init.h>
#include <linux/module.h>
#include <linux/platform_device.h>
#include <linux/of_gpio ...
