Because this is a rk3568 you can probably also add:

  mmc-ddr-1_8v;
  mmc-hs400-1_8v;
  mmc-hs400-enhanced-strobe;

and a pinctrl with emmc_datastrobe according to schematic:

  pinctrl-0 = <&emmc_bus8 &emmc_clk &emmc_cmd &emmc_datastrobe>;

The sdmmc0 node is not needed:
- bus-width is set in linux dts
- bootph-pre-ram is set in rk356x-u-boot.dtsi
- u-boot,spl-fifo-mode is not needed on rk356x

Recommended to be bootph-all, in case TPL support gets added in future.

REGULATOR_PWM and DM_REGULATOR_GPIO is not referenced in device tree.
DM_REGULATOR_FIXED is selected in arch Kconfig

I would recommend running moveconfig.py to clean up/re-order this file.
