No need to pass bootargs here.

Building with W=1 should give a dtc warning due to the unit address
and reg mismatch.
Oh that makes sense.
I guess I'm going to have to figure out how to get warnings to work as I
couldn't last time I tried.
Oh i got it to work I did something dumb...
I didn't give a warning for this i still changed it of course.

Unneeded blank line.

No need for this imxrt1050-evk container.
I was wondering if that was needed, u-boot has it, good to know.

Put it on a single line. It helps readability. Same applies globally.

+ pinctrl-names = "default", "state_100mhz", "state_200mhz", "sleep";
+ pinctrl-0 = <&pinctrl_usdhc0>;

+

Make 'status' to be the last property. Remove the blank line.

Please group more elements into the same line.

Putting one entry per line makes it extremely long.

+ gpio5: gpio@400c0000 {
+ compatible = "fsl,imxrt-gpio", "fsl,imx35-gpio";
+ reg = <0x400c0000 0x4000>;
+ interrupts = <88>,
+ <89>;

Put the interrupts into a single line.

Ah all these make sense, will fix, sry about that.
