rk3288移植spi(fpc1020)数据传输和设备树配置问题

各位大神，请指教spi（fpc1020）android驱动移植过程中设备树配置和数据传输过程是否有错误的地方，问题应该在哪，怎么解决？请指点！
下面是设备树配置在spi0里面的配置：
&spi0 {
status = “okay”;
max-freq = <48000000>;

    fpc1020@00 {
            compatible = "fpc,fpc1020";
            reg = <0>;
            spi-max-frequency = <24000000>;
            //spi-cpha;
            //spi-cpol;
            poll_mode = <0>;
            type = <0>;
            enable_dma = <0>;
          fpc,gpio_reset = <&gpio8 GPIO_A6 GPIO_ACTIVE_LOW>;
          fpc,gpio_irq = <&gpio8 GPIO_A7 IRQ_TYPE_LEVEL_HIGH>;
            fpc,gpio_cs = <>;
            status = "okay";
    };

};
下面是fpc驱动程序读取设备树参数和数据的子函数：
static int __devinit fpc1020_get_of_pdata(struct device *dev,
struct fpc1020_platform_data *pdata)
{
const struct device_node node = dev->of_node;
/ required properties */
const void *irq_prop = of_get_property(node, “fpc,gpio_irq”, NULL);
const void *rst_prop = of_get_property(node, “fpc,gpio_reset”, NULL);
const void *cs_prop = of_get_property(node, “fpc,gpio_cs”, NULL);

/* optional properties */
const void *vddtx_prop = of_get_property(node, "fpc,vddtx_mv", NULL);
const void *boost_prop =
		of_get_property(node, "fpc,txout_boost_enable", NULL);

if (node == NULL) {
	dev_err(dev, "%s: Could not find OF device node\n", __func__);
	goto of_err;
}

if (!irq_prop || !rst_prop || !cs_prop) {
	dev_err(dev, "%s: Missing OF property\n", __func__);
	goto of_err;
}

pdata->irq_gpio   = be32_to_cpup(irq_prop);
pdata->reset_gpio = be32_to_cpup(rst_prop);
pdata->cs_gpio    = be32_to_cpup(cs_prop);

pdata->external_supply_mv =
		(vddtx_prop != NULL) ? be32_to_cpup(vddtx_prop) : 0;

pdata->txout_boost = (boost_prop != NULL) ? 1 : 0;

return 0;

of_err:
pdata->reset_gpio = -EINVAL;
pdata->irq_gpio = -EINVAL;
pdata->cs_gpio = -EINVAL;

pdata->external_supply_mv = 0;
pdata->txout_boost = 0;

return -ENODEV;

}
原本我用的是 fpc,gpio_reset = <&gpio8 GPIO_A6 GPIO_ACTIVE_LOW>;管脚号应该是262，但是打印出来的log却是fpc1020 spi0.0: Assign HW reset → GPIO151 151 很明显不对，是大小端函数处理错误吗？还是管脚地址传输错误了？读取设备节点的属性函数用的对吗？还是用其他函数呢？望高人指点呀！
