Thank you a lot for doing this massive conversion work of NXP LPC
device tree bindings, I would appreciate, if you put me to CC for
all such changes.

While you do one-to-one conversion, you do bring a lot of errors,
because the .txt descriptions are broken.

Please always reference to arch/arm/boot/dts/nxp/lpc/lpc32xx.dtsi
and arch/arm/boot/dts/nxp/lpc/lpc18xx.dtsi, that's the correct
version of NXP LPC DT bindings, otherwise something important
can be missed by occasion.

interrupt-parent = <sic1>;

Should subscribe 32 and correct the type:

interrupts = <29 4>, <30 4>, <28 4>, <26 8>;
