TDA4VM: R5和与A72 配置GPIO冲突

pitang niu

Part Number: TDA4VM

使用官方提供的systool将底层的pinmux重新整理了一遍，在系统中目前是可以找到所有的GPIO了

但是当我在MCU1_0中启用了csl库的gpio初始化函数，函数如下

#define PWM_IN1_PORT 1
#define PWM_IN1_PIN 13
#define PWM_IN1_CFG 0

#define PWM_IN2_PORT 1
#define PWM_IN2_PIN 14
#define PWM_IN2_CFG 1

#define PWM_IN3_PORT 1
#define PWM_IN3_PIN 11
#define PWM_IN3_CFG 2

#define PWM_IN4_PORT 0
#define PWM_IN4_PIN 60
#define PWM_IN4_CFG 3

GPIO_PinConfig MygpioPinConfigs[] =
{
    /* Input pin with interrupt enabled */
    GPIO_DEVICE_CONFIG(PWM_IN1_PORT, PWM_IN1_PIN) | GPIO_CFG_IN_INT_RISING | GPIO_CFG_INPUT,
    GPIO_DEVICE_CONFIG(PWM_IN2_PORT, PWM_IN2_PIN) | GPIO_CFG_IN_INT_RISING | GPIO_CFG_INPUT,
    GPIO_DEVICE_CONFIG(PWM_IN3_PORT, PWM_IN3_PIN) | GPIO_CFG_IN_INT_RISING | GPIO_CFG_INPUT,
    GPIO_DEVICE_CONFIG(PWM_IN4_PORT, PWM_IN4_PIN) | GPIO_CFG_IN_INT_RISING | GPIO_CFG_INPUT,
};

GPIO_CallbackFxn MygpioCallbackFunctions[] =
{
    NULL,
    NULL,
    NULL,
    NULL,
};

void Cap_init()
{
    uint8_t bank_num = 0;

    GPIO_v0_HwAttrs gpio_cfg1;
    GPIO_v0_HwAttrs gpio_cfg2;
    GPIO_v0_HwAttrs gpio_cfg3;
    GPIO_v0_HwAttrs gpio_cfg4;

    GPIO_socGetInitCfg(PWM_IN4_PORT, &gpio_cfg4);
    gpio_cfg4.baseAddr = CSL_WKUP_GPIO0_BASE;
    // bank_num = PWM_IN4_PIN/16;
    // gpio_cfg4.intCfg[PWM_IN4_PIN].intNum = CSLR_GPIOMUX_INTRTR0_IN_GPIO0_GPIO_BANK_0 + bank_num;
    // gpio_cfg4.intCfg[PWM_IN4_PIN].intcMuxNum = INVALID_INTC_MUX_NUM;
    // gpio_cfg4.intCfg[PWM_IN4_PIN].intcMuxInEvent = 0;
    // gpio_cfg4.intCfg[PWM_IN4_PIN].intcMuxOutEvent = 0;
    GPIO_configIntRouter(PWM_IN4_PORT, PWM_IN4_PIN, 0, &gpio_cfg4);
    GPIO_socSetInitCfg(PWM_IN4_PORT, &gpio_cfg4);

    GPIO_socGetInitCfg(PWM_IN1_PORT, &gpio_cfg1);
    gpio_cfg1.baseAddr = CSL_GPIO1_BASE;
    // gpio_cfg1.intCfg[PWM_IN1_PIN].intNum = CSLR_GPIOMUX_INTRTR0_IN_GPIO0_GPIO_BANK_0 + bank_num;
    // gpio_cfg1.intCfg[PWM_IN1_PIN].intcMuxNum = INVALID_INTC_MUX_NUM;
    // gpio_cfg1.intCfg[PWM_IN1_PIN].intcMuxInEvent = 0;
    // gpio_cfg1.intCfg[PWM_IN1_PIN].intcMuxOutEvent = 0;
    GPIO_configIntRouter(PWM_IN1_PORT, PWM_IN1_PIN, 0, &gpio_cfg1);
    GPIO_socSetInitCfg(PWM_IN1_PORT, &gpio_cfg1);

    GPIO_socGetInitCfg(PWM_IN2_PORT, &gpio_cfg2);
    gpio_cfg2.baseAddr = CSL_GPIO1_BASE;
    GPIO_configIntRouter(PWM_IN2_PORT, PWM_IN2_PIN, 0, &gpio_cfg2);
    GPIO_socSetInitCfg(PWM_IN2_PORT, &gpio_cfg2);

    GPIO_socGetInitCfg(PWM_IN3_PORT, &gpio_cfg3);
    gpio_cfg3.baseAddr = CSL_GPIO1_BASE;
    GPIO_configIntRouter(PWM_IN3_PORT, PWM_IN3_PIN, 0, &gpio_cfg3);
    GPIO_socSetInitCfg(PWM_IN3_PORT, &gpio_cfg3);

    GPIO_v0_config.pinConfigs = MygpioPinConfigs;
    GPIO_v0_config.callbacks = MygpioCallbackFunctions;
    GPIO_v0_config.numberOfPinConfigs = sizeof(MygpioPinConfigs) / sizeof(GPIO_PinConfig);
    GPIO_v0_config.numberOfCallbacks = sizeof(MygpioCallbackFunctions) / sizeof(GPIO_CallbackFxn);
    GPIO_v0_config.intPriority = 0x8;

    GPIO_init();

    GPIO_setCallback(PWM_IN1_CFG, PwmInCap1Callback);
    GPIO_enableInt(PWM_IN1_CFG);

    GPIO_setCallback(PWM_IN2_CFG, PwmInCap2Callback);
    GPIO_enableInt(PWM_IN2_CFG);

    GPIO_setCallback(PWM_IN3_CFG, PwmInCap3Callback);
    GPIO_enableInt(PWM_IN3_CFG);

    GPIO_setCallback(PWM_IN4_CFG, PwmInCap4Callback);
    GPIO_enableInt(PWM_IN4_CFG);
}

linux的设备树如下（节选）：

&wkup_gpio0 {
	pinctrl-names = "default";
	pinctrl-0 = <&wakegpio0_pins_default>;
};

&main_gpio0 {
	pinctrl-names = "default";
	pinctrl-0 = <&mygpio0_pins_default>;
};

&main_gpio1 {
	pinctrl-names = "default";
	pinctrl-0 = <&mygpio1_pins_default>;
};

当包含着上述的系统在启动时，其日志会打印报错：

[ 3.805209] davinci_gpio 42110000.gpio: IRQ index 3 not found
[ 3.810951] davinci_gpio 42110000.gpio: error -ENXIO: IRQ not populated
[ 3.821153] davinci_gpio 601000.gpio: IRQ index 0 not found
[ 3.826738] davinci_gpio 601000.gpio: error -ENXIO: IRQ not populated

启动后，就找不到wakeup和GPIO1的控制端口了；

我不太理解Cls gpio库的初始化函数怎么会与davinci_gpio的驱动函数起冲突，请问有没有人能解释下问题？其实调用CLS库也是为做GPIO中断，我怀疑是在找寻中断号的过程中起了冲突，如果是这样请问该如何解决呢？

目前我检查了所有的相关配置，发现问题出在

        if(setIntrPath)
        {
            (void)memset (&rmIrqReq,0,sizeof(rmIrqReq));

            rmIrqReq.secondary_host         = TISCI_MSG_VALUE_RM_UNUSED_SECONDARY_HOST;
            rmIrqReq.src_id                 = src_id;
            rmIrqReq.src_index              = src_index;  /* This is the event coming out of
            the peripheral */

            /* Set the destination interrupt */
            rmIrqReq.valid_params          |= TISCI_MSG_VALUE_RM_DST_ID_VALID;
            rmIrqReq.valid_params          |= TISCI_MSG_VALUE_RM_DST_HOST_IRQ_VALID;

            /* Set the destination based on the core */
            rmIrqReq.dst_id                 = dst_id;
            rmIrqReq.dst_host_irq           = dst_host_irq;
            if(GPIO_PinBankUsageCount[portNum][bankNum] == 0U) {
                retVal = Sciclient_rmIrqSet(
                            (const struct tisci_msg_rm_irq_set_req *)&rmIrqReq,
                            &rmIrqResp,
                            SCICLIENT_SERVICE_WAIT_FOREVER);

                if(retVal==CSL_PASS) {
                    /* Increase the bank usage count for this port */
                    GPIO_PinBankUsageCount[portNum][bankNum]++;
                }
                } else {
                    /* The interrupt path is already allocated, no need to re-allocate it */
                    retVal = CSL_PASS;
                }
        }

这部分作用是用来注册中断路由到指定路劲，注册成功后linux在注册中断时，对应的标志位会出现注册失败的情况，请问MCU1_0注册中断与A72是不能冲突吗？

艹了，什么玩意，妈的A72起来重写我的IO 寄存器，我佛了！
