[SOLVED] iMX6 spi not showing up in /dev/ but does show in /sys/class/spi_master/

I'm not great at Linux - especially not on the hardware side. I'm trying to active spi bus to control a peripheral device.

I have edited my device tree as follows:

&ecspi1 {
    fsl,spi-num-chipselects = <1>;
    cs-gpios = <&gpio2 30 GPIO_ACTIVE_HIGH>;
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_ecspi1>;
    status = "okay";

	 spidev@0 { /* NINA-B221-00B Bluetooth device*/
        compatible = "spidev";
        reg = <0>;
        spi-max-frequency = <1000000>;
        status = "okay";
    };
};

I have uploaded the new .dtb to my device though the manufacturing tool - yet there is no SPI devices showing in /dev/

/sys/bus/platform/drivers/spi_imx/ exists and has the correct files in it.

in /sys/class/spi_master/spi0/device/spi_master/spi0/spi0.0
I can do "cat uevent"

{root}37 cat uevent
OF_NAME=spi
OF_FULLNAME=/soc/aips-bus@02000000/spba-bus@02000000/ecspi@02008000/spi@0
OF_COMPATIBLE_0=spidev
OF_COMPATIBLE_N=1
MODALIAS=spi:spidev

address looks good at 2008000 according to data sheet:
/soc/aips-bus@02000000/spba-bus@02000000/ecspi@02008000

Yet still, noting named 'spi' in /dev/

I might have an idea of what is going on, I'm looking at "make menuconfig" and under SPI Support the only thing that is selected is
"Utilities fo Bitbanging SPI masters"

However, there are A LOT of options to choose from here...

Under
"*** SPI PROTOCOL MASTERS***"

[] User mode SPI device driver support


is not selected. Should it be?

There are so many options here and I have no idea what any of them do.

The solution was to activate
User mode SPI device driver support
in the config.
