sdhci-tegra driver patch implements set_timeout callback based on one of
the sdhci host driver patch that refactors sdhci_set_timeout and allows
drivers to call __sdhci_set_timeout with their timeout callback
implementation.
Both of these patches are manually backported in this series.
a new feature. What's wrong with just using the 5.4.y kernel tree?

MMC_CAP_NEED_RSP_BUSY for sdhci-tegra as well.
So, it will always use R1B for R1B type commands so there are no known bugs
or failures with mmc devices we use on our platforms.
So, we can treat this patch as an improvement for long operation commandsOk, so this isn't a regression and can't match the stable kernel rules,
where HW will wait as long as device is busy.
sorry.
patch fixes a long outstanding bug for sdhci-tegra.
For some SD/MMC commands, the mmc core may provide a long busy timeout
trusting the mmc host to cope with it. It has turned out that
sdhci-tegra didn't, thus it may report a cmd-timeout error, while in
fact it shouldn't.
I believe that is what the small series of patches should be addressing.
Kind regards
