mmc: sdhci-tegra: Issue CMD and DAT resets together
[ Upstream commit
acc13958c2b2623c17e2450b8cd6881b698756d3 ]
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.
