器件型号：AM62L

工具/软件：

您好、

参考：待定：arm64：dts：TI：k3-am62l：启用 MMC 高速模式 — ti-linux-kernel/ti-linux-kernel — 此存储库包含一个 Linux 内核、该内核已与基于 kernel.org 上的开源 Linux 内核的出色 TI 开源补丁集成。需要将对此内核的贡献发送到开源社区进行审核。

在器件树中切换到高速模式后、sdhci0 和 sdhci2 都会显示以下错误。此问题偶尔会发生、而且概率较低。

您好：

已发布的 SDK v11.0 中未启用 HS200 模式。那么、您是在处理“ti-linux-6.12.y"分支“分支、还是将该补丁反向移植到内核标签 11.00.05？

谢谢！

您好、

修补程序仅回移植到内核标签 11.00.05。

您好、

对此问题有任何更新？目前、我已从内核标签 11.00.05 中删除 MMC 高速模式补丁并恢复到默认 MMC 设备树、但问题仍然存在。
