Thanks a lot for the review!

The above should be enough.

quoted

  	max-frequency = <100000000>;
  	disable-wp;
  
  	cd-gpios = <&gpio CARD_6 GPIO_ACTIVE_LOW>;
  
  	vmmc-supply = <&tflash_vdd>;
-	vqmmc-supply = <&tf_io>;

... but do not remove that.

That way the description is complete and the kernel is able to verify
the regulator is properly configured.

Thanks for the hint! I didn't thought about this while working on it, 
but I tried it today and it worked perfectly.

It is also easier for a bootloader to alter DT to add the UHS modes back
(it is safe to do so if booting from another device that SD, such as
eMMC)

This sounds like a nice improvement as well.
