+=====================
+工业 IIO configfs支持
+=====================
+
+1. 概述
+=======
+
+Configfs是一种内核对象的基于文件系统的管理系统,IIO使用一些可以通过
+configfs轻松配置的对象(例如:设备,触发器)。
+
+关于configfs是如何运行的,请查阅Documentation/filesystems/configfs.rst
+了解更多信息。
+
+2. 用法
+=======
+为了使configfs支持IIO,我们需要在编译时选中config的CONFIG_IIO_CONFIGFS
+选项。
+
+然后,挂载configfs文件系统(通常在 /config directory目录下)::
+
+  $ mkdir/config
+  $ mount -t configfs none/config
+
+此时,将创建所有默认IIO组,并可以在/ config / iio下对其进行访问。 下一章
+将介绍可用的IIO配置对象。
+
+3. 软件触发器
+=============
+
+IIO默认configfs组之一是“触发器”组。 挂载configfs后可以自动访问它,并且可
+以在/config/iio/triggers下找到。
+
+IIO软件触发器为创建多种触发器类型提供了支持。 通常在include/linux/iio
+/sw_trigger.h:中的接口下将新的触发器类型实现为单独的内核模块:
+::
+
+  /*
+   * drivers/iio/trigger/iio-trig-sample.c
+   * 一种新触发器类型的内核模块实例
+   */
+  #include <linux/iio/sw_trigger.h>
+
+
+  static struct iio_sw_trigger *iio_trig_sample_probe(const char *name)
+  {
+	/*
+	 * 这将分配并注册一个IIO触发器以及其他触发器类型特性的初始化。
+	 */
+  }
+
+  static int iio_trig_sample_remove(struct iio_sw_trigger *swt)
+  {
+	/*
+	 * 这会废弃iio_trig_sample_probe中的操作
+	 */
+  }
+
+  static const struct iio_sw_trigger_ops iio_trig_sample_ops = {
+	.probe		= iio_trig_sample_probe,
+	.remove		= iio_trig_sample_remove,
+  };
+
+  static struct iio_sw_trigger_type iio_trig_sample = {
+	.name = "trig-sample",
+	.owner = THIS_MODULE,
+	.ops = &iio_trig_sample_ops,
+  };
+
+module_iio_sw_trigger_driver(iio_trig_sample);
+
+每种触发器类型在/config/iio/triggers下都有其自己的目录。 加载iio-trig-sample
+模块将创建“ trig-sample”触发器类型目录/config/iio/triggers/trig-sample.
+
+我们支持以下中断源(触发器类型)
+
+	* hrtimer,使用高分辨率定时器作为中断源
+
+3.1 Hrtimer触发器创建与销毁
+---------------------------
+
+加载iio-trig-hrtimer模块将注册hrtimer触发器类型,从而允许用户在
+/config/iio/triggers/hrtimer下创建hrtimer触发器。
+
+例如::
+
+  $ mkdir /config/iio/triggers/hrtimer/instance1
+  $ rmdir /config/iio/triggers/hrtimer/instance1
+
+每个触发器可以具有一个或多个独特的触发器类型的属性。
+
+3.2 "hrtimer" 触发器类型属性
+----------------------------
+
+"hrtimer”触发器类型没有来自/config dir的任何可配置属性。
+但它确实将采样频率属性引入了触发目录。
