QRB2210 SPI设备在qupv3_se0_SPI上的漏洞问题
我试图使用对下面的设备树所做的修改在QRB2210上启动SPI设备，但在dmesg中遇到以下错误，并且在/dev目录中找不到可用的spidev设备：
/ # dmesg | grep spi
[ 10.610471] scuba-pinctrl 500000.pinctrl: pin-0 (4a80000.spi) status -22
[ 10.627878] spi_geni 4a80000.spi: Error applying setting, reverse things back
[ 10.635143] spi_geni: probe of 4a80000.spi failed with error -22
/ #
您能帮助描述这些错误消息并提供建议，以帮助我们使用qupv3_se0_SPI接口初始化QRB2210 devkit上的SPI设备吗？
以下是我们的DTS:

需要修改device-tree的代码:
apps_proc/src/vendor/qcom/proprietary/devicetree/qcom/scuba.dtsi 中添加

&qupv3_se0_spi {
    status = "ok";
};

需要修改的kernel的代码:
drivers/pinctrl/qcom/pinctrl-scuba.c 改为

static const int scuba_reserved_gpios[] = {
//    0, 1, 2, 3, 14, 15, 16, 17, -1
    14, 15, 16, 17, -1
};
/*
static const struct msm_gpio_wakeirq_map scuba_mpm_map[] = {
