我有一个 ls1046a 载板，想使用 QSPI_B （用作 SPI，即仅使用 QSPI_B_SCK、QSPI_B_DATA0 和 QSPI_B_DATA1） 来连接 mcp2518fd（spi 到 can 控制器）。
请查看我在下面的 fsl-ls1046a-rdb.dts 中所做的更改。
&qspi {
status = \"okay\";
// added by Yen for mcp2518fd
can0@2 {
compa
tible = \"microchip,mcp2518fd\";
reg = <2>;
clocks = <&mcp2518fd_osc>;
spi-max-frequency = <20000000>;
interrupt-parent = <&gpio0>;
interrupts = <27 IRQ_TYPE_LEVEL_LOW>; // Change to IRQ07/GPIO1_27, IRQ_TYPE_LEVEL_LOW/IRQ_TYPE_EDGE_FALLING
vdd-supply = <&sb_3v3>;
xceiver-supply = <&sb_5v0>;
};

有谁知道如何解决这个问题？
