| Subject | [PATCH] UHS-SD card for Hisilicon Hikey |
| Message-ID | <s21B0-1hs-15@gated-at.bofh.it> |
mmc: dw_mmc-k3: Hisilicon Hikey have no tuning function in dw_mmc-k3.c,so we must do the tuning function stub when we init UHS card.

Refer to Shawn's previous comment.
"No, please amend the commit title line as "mmc: dw_mmc: xxxxx"
And add "linux-mmc@vger.kernel.org", patch version, Changelog, etc..
Best Regards,
Jaehoon Chung
