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.

Are there really these big gaps in the register space i.e 0x1100 -> 0x2000 etc?

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@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!

Once my comments have been rectified, feel free to add my:
