Might consider submitting a MAINTAINERS entry for all of ST's DTS(I)

I won't mention this particular point again, but it needs to be
propagated throughout the patch.

Space after colon and another after the address.

Same for all of the nodes below and throughout the patch.

This might just be a personal thing, but I prefer to see the status at
the base of the node with a new line above it, as it is only relevant
to the node rather than the device.

Like this:
	serial at 9830000{
		compatible = "st,asc";
		reg = <0x9830000 0x2c>;
		interrupts = <GIC_SPI 122 IRQ_TYPE_NONE>;
		pinctrl-names = "default";
		pinctrl-0 = <&pinctrl_serial0>;
		clocks = <&CLK_EXT2F_A9>;

		status = "disabled";
	};

Not sure if this is Git playing around again, but the };s look
misaligned in the submission.

Wow, this is good work and a lot of code!
