至少速率要修复成正确的值，然后提测。如果没问题再合并 |
This change is based on this commit[0]. However, the property 'enable-strobe-pulldown' has already been set[1]. We just need to set 'mmc-hs400-1_8v' and 'mmc-hs400-enhanced-strobe' in this change. For testing compactability, the following eMMCs were tested on Rock 4B: Foresee 16G, 32G, 64G Samsung 16G, 32G, 128G Sandisk 8G, 16G [0]: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f720dd9b8b6d8b2160beda789429d5489ce8a099 [1]: radxa@b045498 Signed-off-by: Zhaoming Luo <[email protected]>

另外8g emmc可以用cli镜像吧，不过应该不需要重新测试恶劣
