基于A31s的AP6210驱动调试

按照《A31s平台wifi移植说明》的相关步骤配置完成

在修改sys_config.fex的ap6xxx_clk_power     = "axp22_dldo4"后32.768K的时钟输出有了

修改Wifi_pm_ap6xxx.c (arch\arm\mach-sun6i\rf) 函数：

static int ap6xxx_gpio_ctrl(char* name, int level)
{
int i = 0;
int ret = 0;
int gpio = 0;
unsigned long flags = 0;
char * gpio_name[2] = {"ap6xxx_wl_regon", "ap6xxx_bt_regon"};


for (i = 0; i < 2; i++) {
if (strcmp(name, gpio_name[i]) == 0) {
switch (i)
{
case 0: /*ap6xxx_wl_regon*/
//gpio = ap6xxx_wl_regon;
gpio = GPIOM(0);
break;
case 1: /*ap6xxx_bt_regon*/
//gpio = ap6xxx_bt_regon;
break;
default:
ap6xxx_msg("no matched gpio.\n");
}
break;
}
}


if (1==level)
flags = GPIOF_OUT_INIT_HIGH;
else
flags = GPIOF_OUT_INIT_LOW;


ret = gpio_request_one(gpio, flags, NULL);
if (ret) {
ap6xxx_msg("failed to set gpio %s to %d !\n", name, level);
return -1;
} else {
gpio_free(gpio);
ap6xxx_msg("succeed to set gpio %s to %d !\n", name, level);
}


return 0;
}

void ap6xxx_power(int mode, int *updown)
{
    if (mode) {
        if (*updown) {
//ap6xxx_gpio_ctrl("ap6xxx_wl_regon", 1);
gpio_request_one(GPIOM(0),GPIOF_OUT_INIT_HIGH,NULL);
mdelay(200);
        } else {
//ap6xxx_gpio_ctrl("ap6xxx_wl_regon", 0);
gpio_request_one(GPIOM(0),GPIOF_OUT_INIT_LOW,NULL);
mdelay(100);
        }
        ap6xxx_msg("sdio wifi power state: %s\n", *updown ? "on" : "off");
    }
    return;
}

这时ap6xxx_wl_regon引脚可以拉高，内核的报错信息如下：
