做S3C2410的驱动比较重要的几个文件

转自——hantown原创

做S3C2410的驱动，下面几个文件是必须去认真关注的：

include/asm-arm/arch-s3c2410/irqs.h定义了中断相关的各种宏

include/asm-arm/arch-s3c2410/regs-gpio.h定义了各种GPIO

arch/arch/arm/plat-s3c24xx/gpio.c 定义了各种GPIO操作函数

arch/arch/arm/plat-s3c24xx/devs.c定义了s3c24XX平台下的各种platform_device和resource资源；如果在这里找不到资源，可以自己用struct resource XXXXX_resource ，

和struct platform_device platform_device_XXXXX= {

 .name    = "ST2410_XXXXX",

 .id    = 1,

 .num_resources   = ARRAY_SIZE( XXXXX_resource ),

 .resource   = XXXXX_resource ,

};

来定义

 

 

//define in file include/asm-arm/arch-s3c2410/irqs.h

//#define IRQ_EINT0      S3C2410_IRQ(0)     /* 16 */

//#define S3C2410_IRQ(x) ((x) + S3C2410_CPUIRQ_OFFSET)

//#define S3C2410_CPUIRQ_OFFSET  (16)

//define in file include/asm-arm/arch-s3c2410/regs-gpio.h

//#define S3C2410_GPF0        S3C2410_GPIONO(S3C2410_GPIO_BANKF, 0)

//#define S3C2410_GPF0_INP    (0x00 << 0)

//#define S3C2410_GPF0_OUTP   (0x01 << 0)

//#define S3C2410_GPF0_EINT0  (0x02 << 0) setup GPF0 is EINT0，Falling edge triggered

//#define S3C2400_GPF0_RXD0   (0x02 << 0)

//the function defined in file arch/arch/arm/plat-s3c24xx/gpio.c

//s3c2410_gpio_setpin(gpio, value);setup value of XX pin 

//extern int s3c2410_gpio_irq2pin(unsigned int irq);get pin of XX irq

//unsigned int s3c2410_gpi

o_getpin(unsigned int pin);get vlaue of XX pin
