I recommend using clkm1_32k_out at the sdio-pwrseq node.

Maybe `brcm,bcm4329-fmac` nodes can be added here?

You can add `brcm,bcm43438-bt` nodes here:
bluetooth {
compatible = "brcm,bcm43438-bt";
device-wakeup-gpios = <&gpio3 RK_PC3 GPIO_ACTIVE_HIGH>;
host-wakeup-gpios = <&gpio1 RK_PC2 GPIO_ACTIVE_HIGH>;
shutdown-gpios = <&gpio1 RK_PC1 GPIO_ACTIVE_HIGH>;
...
};

Not sure, have changed to use mmc-pwrseq in v2.

Thanks, will remove the clock-output-names for the Sige1 and the NanoPi
Zero2 in v2, #clock-cells seem to be required by the dt-bindings.

Will use something similar in v2.
See [1] for fixups I am testing for v2.
