| Subject: Revert "mmc: sdhci: Fix incorrect switch to HS mode" |
| |
| From: Faiz Abbas <faiz_abbas@ti.com> |
| |
| commit 07bcc411567cb96f9d1fc84fff8d387118a2920d upstream. |
| |
| This reverts commit c894e33ddc1910e14d6f2a2016f60ab613fd8b37. |
| |
| This commit aims to treat SD High speed and SDR25 as the same while |
| setting UHS Timings in HOST_CONTROL2 which leads to failures with some |
| SD cards in AM65x. Revert this commit. |
| |
| The issue this commit was trying to fix can be implemented in a platform |
| specific callback instead of common sdhci code. |
