How to Configure DTS and Struct for SPI Controller Driver with Child Nodes in Zephyr?
Hello Guys,
I am developing a SPI Controller Driver for TI processors for Zephyr,
I have a doubt on how do i set the Dts to look like?
ideally it should like this if we include soc.dtsi, board.dts, overlay.dts
As of now, I am getting the SPI controller to have 4 CS, no DMA, no slave mode
how do i set my struct config to accomodate the above?
it would be simple if there was no child nodes
like the below
but with child nodes in the equation, i am so confused...

&spi1 {

interrupts = <25>;
#address-cells = <1>;
#size-cells = <0>;
spi1_device0: spi-device@0 {

spi-max-frequency = <1000000>;
spi-cs-delay = <5>;
word_length = <8>
};
spi1_device1: spi-device@1 {
reg = <1>;
spi-max-frequency = <2000000>;
spi-cs-delay = <10>;
word_length = <32>
};
};As of now, I am getting the SPI controller to have 4 CS, no DMA, no slave mode

like the below
struct spi_omap_config {
DEVICE_MMIO_NAMED_ROM(base);
uint32_t irq;
};but with child nodes in the equation, i am so confused...
