==================================
思睿逻辑 EP93xx 模拟数字转换器驱动
==================================

1. 概述
=======

该驱动同时适用于具有5通道模拟数字转换器的低端 (EP9301, Ep9302) 设备和10通道
触摸屏/模拟数字转换器的高端设备(EP9307, EP9312, EP9315)。

2. 通道编号
===========

EP9301和EP9302数据表定义了通道0..4的编号方案。虽然EP9307, EP9312和EP9315多
了3个通道（一共8个），但是编号并没有定义。所以说最后三个通道是随机编号的。

如果ep93xx_adc是IIO设备0，您将在以下位置找到条目
/sys/bus/iio/devices/iio:device0/:
