How to configure and setup an SPI device to nRF5340

[Learner]

Hello,

I am trying to setup a device (Semtech LR1110) connected to SPI 1 peripheral on the nRF5340pdk.

I have a driver code for it. My question is this.

How can I set it up in the .dts file and keep the code that drives it with my source code on my local drive without having to put it the C:\Zypher\v1.3.0\zephyr\drivers\LR1110?

Q1/ Will the proposed Device Tree fragment do the job?

...

...

spi1: spi@9000 {
   compatible = "nordic,nrf5340";

   status = "okay";

   reg = < 0x9000 0x1000 >;

   interrupts = < 0x9 0x1 >;
   label = "SPI_1";

   sck-pin = < 0x?? >;
   mosi-pin = < 0x?? >;
   miso-pin = < 0x?? >;

};      

Q2/ How do I get the device binding to work?

Will this work?

device_get_binding( DT_PROP( DT_NODELABEL(spi1), label );

Thank you.

Kind regards
