am3352 mcasp0_ahclkr(gpio3_17)无法产生中断?



Dear all,

请教一个问题:

使用SDK7.0,在DTS设置mcasp0_ahclkr

0x19C (PIN_INPUT_PULLUP | MUX_MODE7) //gpio3_17

驱动中配置

ret = gpio_request_one(GPIO_TO_PIN(3, 17), GPIOF_IN, "irq");

中断产生的时候,信号变低,无法恢复高电平,同样换用GPIO3_21,中断可以恢复高电平。

0x1AC (PIN_INPUT_PULLUP | MUX_MODE7) //gpio3_21

驱动中配置

ret = gpio_request_one(GPIO_TO_PIN(3, 21), GPIOF_IN, "irq");

系统初始化没有使用McASP相关模块。

mcasp0_ahclkr(gpio3_17)有bug吗?

谢谢
