Sorry for the noise here:), but I find there is some mmc stuff
which confuse me. Maybe Randy could elaborate more?

Your sdmmc claims to support UHS-I mode like sd-uhs-sdr104, etc, which
will ask dw_mmc to switch vqmmc from 3V3 to 1V8 after sending CMD11.

But the vqmmc is vccio_sd which is fixed as 3V3? :)

so far we have only been able to achieve UHS speeds on devices based on the 
rk808 pmic (I had sucess on veyron and popmetal). The act8846-based boards 
seem to have some issue when trying to do the switch to 1.8V, resulting in 
mmc errors and the mmc-core switching back to 3.3V.

I think this might be caused by a bug in the act8846 driver or some dts 
mistake. But so far nobody had the time and enthusiasm to investigate :-)

Hi all,
sdcard-supply must be specifed  in io-domains node to enable uhs.

io-domains {
compatible = "rockchip,rk3288-io-voltage-domain";
rockchip,grf = <&grf>;
sdcard-supply = <&vccio_sd>;
wifi-supply = <&vcc_18>;
};

well，it has already been added....

The root cause is not act8846. Firefly have a bug with sdmmc and it
seems they didn't fix it in firefly-reload.

Yes, Jacob is right. Those high speed options need the voltage down to 1.8v. They should be removed.

Thanks Jacob for pointing out this issue - I was always wondering why it 
wasn't working :-) .

Randy, can you provide a follow-up patch that removes these excess properties 
please?


Thanks

I will send a patch in weekend. I need some time to confirm whether
the sdio wifi would meet the same problem in firefly reload.
I found those patches are not been merged yet, should I just send
a new version or just a patch remove those incorrect excess properties?
