请问Tina Linux 5.4环境下，spi1的slave模式应该如何使用？参考Linux SPI开发指南，修改dts
&spi1 {
clock-frequency = <100000000>;
pinctrl-0 = <&spi1_pins_a &spi1_pins_b>;
pinctrl-1 = <&spi1_pins_c>;
pinctrl-names = "default", "sleep";
spi_slave_mode = <1>;
spi1_cs_number = <1>;
spi1_cs_bitmap = <1>;
status = "okay";
spi_board1@0 {
device_type = "spi_board1";
compatible = "rohm,dh2228fv";
spi-max-frequency = <0x5f5e100>;
reg = <0x0>;
spi-rx-bus-width = <0x1>;
spi-tx-bus-width = <0x1>;
status = "okay";
};
};
无spidev设备生成，文档slave参考示例没法用
