Mainline: MMC-Error -110 on Vacuum

[EliasKotlyar]

Hello everyone,

I am trying to port the Mainline Kernel to the Xiaomi RoboRock-Vacuum.
Here is a brief description:
http://linux-sunxi.org/Xiaomi-RoboRock-V1

Basically, its a A33 with a eMMC attached to MMC2-Port. MMC0 is not available on the system.
I had some issues regarding the eMMC on U-Boot, because it was not able to change the clock of the mmc. I was able to fix it by setting "calibrate = true;" in mmc_set_mod_clk. Afterwars the clock was setting fine, and everything started working. Basically, it was the same error as described here:
https://lists.denx.de/pipermail/u-boot/2016-September/266350.html

Unfortunately, i have a similar issue with the kernel driver now. However i am not sure how to fix. I have tried setting the calibrate to true, but it does not give any different result. Here is the kernel log:

Can someone point me to the right direction? I suppose that it has something to do with the eMMC, which behaves different than a normal microsd.

Hello @EliasKotlyar. I would like to get in touch with you about a private project in which your expertise is much needed. Sorry to leave a comment here, but I could not find your e-mail anywhere. If possible, could you send an e-mail to silvia@devtecnologia.com.br so that I can explain in more detail? Best regards!

[EliasKotlyar]

Hello Silvia,

I have written you an email :)

[nicolaerosia]

@EliasKotlyar was this fixed? are you able to boot mainline?

[EliasKotlyar]

Unfortunately no, i stopped progress on this project, because i could not fix this issue.However i fixxed the same issue on u-boot, so i suppose someone with better debugging capabilitys can do it on the kernel as well. Here is a repo with my patches:
