比如: drivers/rtc/rtc-pxa.c 中写：
/**
* pxa_rtc_probe() - probe function for pxa micco driver
* @pdev: device structure from bus driver
*
* 1. set gpio0_2 as gpio mode and in direction.
*
* 2. register rtc driver to rtc framework
*
* 3. init work queue which will be used in interrupt handler
*
**/
static int pxa_rtc_probe(struct platform_device *pdev)
{
工具生成：
./scripts/kernel-doc -html drivers/rtc/rtc-pxa.c > /mnt/hgfs/share1/rtc-pxa.htm
最后获得：
pxa_rtc_probe - probe function for pxa micco driver
int pxa_rtc_probe (struct platform_device * pdev)
Arguments
pdev
device structure from bus driver
Description
1. set gpio0_2 as gpio mode and in direction.
2. register rtc driver to rtc framework
3. init work queue which will be used in interrupt handler
