前言 I2C总线驱动 compatible = "ti,omap4-i2c"; 对应i2c-omap.c，针对TI该OMAP系列的I2C总线 i2c-omap.c /* * TI OMAP I2C master mode driver * * Copyright (C) 2003 MontaVista Software, Inc. * Copyright (C) 2005 Nokia Corporation * Copyright (C) 2004 - 2007 Texas Instrument

前言 设备树文件的gpio分支 compatible = "ti,omap4-gpio" 对应gpio-omap.c文件 个人感觉每个驱动都有对应的platform驱动去进行初始化，代码有很多应该是直接采用platform驱动的默认值。尚未验证，仅推测。 gpio-omap.c /* * Support functions for OMAP GPIO * * Copyright (C) 2003-2005 Nokia Corporation * Written by Juha Yrjölä &lt

前言 设备树LED部分中显示 compatible = "gpio-leds"; 与/drivers/leds/leds-gpio.c的compatible字样一致，且SDK也指出采用该驱动文件。 leds-gpio.c /* * LEDs driver for GPIOs * * Copyright (C) 2007 8D Technologies inc. * Raphael Assenat <raph@8d.com> * Copyright (C) 2008 Freescale
