linux uart device driver
I am writing a simple UART device driver. I have been referring omap-serial.c as the device driver is for omap-4460 processor. Can i write it using a simple > open,close,write,read and ioctl functions? It is because I did not see these functions in th,Free Electrons legacy Linux kernel training materials.

在linux serial framework中，uart driver是一个平行于platform driver的概念，用于驱动“虚拟”的“串口”设备。举例来说：. 假如一个soc中有5个串口控制器（也可称作uart控制器，后面我们不再区分），每个uart控制器都可引出一个串口（uart port）。那么：. 每个uart控制器，都是一个platform device，由[5]中介绍的dts文... http://www.wowotech.net 大家一起來玩Linux: 如何撰寫一個serial port的驅動程式
所以通常我們要寫的是實體層的驅動程式，在driver的進入點，若是PCI介面，則先註冊一個PCI的call back function，若是local bus則是可以註冊一個platform device call back function，當系統進入你所註冊的call back function，必須對你所使用的硬體介面位址做一個remapping的動作，就是將實體位址轉換成虛擬位 ... https://victoryuembeddedlinux. |
