我需要在TDA4上使用主域的SPI0做MASTER，SPI3做SLAVE。计划采用spidev驱动，请问在设备树中该如何设置。
目前我已经可以识别到spidev节点，但是没有数据发出。其中interputs和clocks配置不确定如何配置，其他配置如下：
main_spi0_pins_default: main_spi0_pins_default {
pinctrl-single,pins = <
J721E_IOPAD(0x1c8, PIN_INPUT, 0) /* (AA1) SPI0_CLK */
J721E_IOPAD(0x1cc, PIN_OUTPUT, 0) /* (AB5) SPI0_D0 */
J721E_IOPAD(0x1d0, PIN_INPUT, 0) /* (AA3) SPI0_D1 */
J721E_IOPAD(0x1c0, PIN_INPUT, 0) /* (AA2) SPI0_CS0 */
>;
};
main_spi3_pins_default: main_spi3_pins_default {
pinctrl-single,pins = <
J721E_IOPAD(0x144, PIN_OUTPUT, 4) /* (Y25) PRG0_PRU1_GPO17.SPI3_CLK */
J721E_IOPAD(0x148, PIN_OUTPUT, 4) /* (AA26) PRG0_PRU1_GPO18.SPI3_D0 */
J721E_IOPAD(0x14c, PIN_INPUT, 4) /* (AA29) PRG0_PRU1_GPO19.SPI3_D1 */
J721E_IOPAD(0x11c, PIN_OUTPUT, 4) /* (AA24) PRG0_PRU1_GPO7.SPI3_CS0 */
>;
};
&main_mcspi0 {
pinctrl-names = "default";
pinctrl-0 = <&main_spi0_pins_default>;
status="okay";
spidev@0 {
spi-max-frequency = <24000000>;
reg = <0>;

};
};
&main_mcspi3 {

};
