> Subject: [PATCH v8 3/3] mmc: sdhci-tegra: Issue CMD and DAT resets
> together
>
> In case of error condition to avoid system crash Tegra SDMMC controller
> requires CMD and DAT resets issued together. SDHCI controller FSM goes
> into bad state due to rapid SD card hot-plug event.
> Issuing reset on the CMD FSM before DATA FSM results in kernel panic,
> hence add support to issue CMD and DAT resets together.
> This is applicable to Tegra186 and later chips.
