One of the patches there needs more discussion, so I regrouped the series with another one, and this is the first outcome. It is solely about max_busy_timeout: Patch 1 is from the previous series (with the comment from Shimoda-san addressed) and sets max_busy_timeout with what TMIO always did. Patch 2 introduces a hook and a default fallback for extended timeout ranges. Patch 3 uses the hook for the extended range of R-Car Gen3 SDHIs. It has been tested that the applied values make sense. I have not measured if the MMC core really sends R1 instead of R1B when the desired timeout value is exceeded. All on a Salvator-XS with R-Car M3N. The patches are based on mmc/next as of today. The branch is here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/sdhi/extop Looking forward to comments!
