What's the extra "pll6d2"? If you have an extra output, it's not compatible with
"allwinner,sun6i-a31-pll6-clk".

And this would be wrong if you don't update the pll6 compatible or driver.
There's no output on n = 2.
You could also chain a fixed divider directly in the driver.

If it weren't for the last 2 clocks, we could cleanly split out apb1 and apb2
gates. Having a separate AHB clock gate taking 2 addresses seems messy
as well. :(

This should be in the board DTS, unless this is the reference design,
in which case you should name the label like "mmc0_cd_pin_reference_design".

Aren't you handling the holes in the bus_rst driver? If so,
isn't it supposed to align both bus_gates and bus_rst indexes?
Same for the other UARTs.

Or in the DT directly.
I'd really like to move away from the various fixed dividers output
that prevents to reuse the clock drivers when it's the only
difference, like what's done here.

The datasheet mentions SDC0_DET function on PF6, so I thought this is
sort of fixed to this pin now. All designs I've seen use this pin.

The reset definitions would be clearer with declarations as the other
Allwinner SoCs and without driver hack:
soc {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges;
dma: dma-controller@01c02000 {
compatible = "allwinner,sun8i-h3-dma";
reg = <0x01c02000 0x1000>;
interrupts = <GIC_SPI 50 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&bus_gates 6>;
resets = <&rst_reg0 6>;
#dma-cells = <1>;
};
...
rst_reg0: reset@01c202c0 {
#reset-cells = <1>;
compatible = "allwinner,sun6i-a31-clock-reset";
reg = <0x01c202c0 0x04>;

rst_reg4: reset@01c202d8 {

Having the bus clocks called bus_* would make more sense I guess, or
at least it would match the datasheet names (as obscure as they are).
Thanks!

What's the u-boot support like these days?
If it's ready, or at least some patches have been sent, you shouldn't
set both the memory node (that will be overriden anyway) and the
clock-frequency and arm,cpu-registers-not-fw-configured properties in
the timer node, that will prevent the kernel from booting there.
Thanks!
