Hi Ulf

Just a gentleman ping about this series.
I sent this series at same time of dt_mode
(no dependence between both).

Thanks for pinging.

It's been a busy period, with travels etc. I am just catching up on
everything and I will soon come back to this.

No problem, I saw lot of power group presentations at linaro connect :-)


I haven't tried to apply this on top of the other recent queued
changes for mmci, but perhaps you can check if a rebase is needed?

I try on the last mmc next, rebase, build and stm32mp157 test OK

Especially since I plan to run this on my ux500 board.

Kind regards
Uffe

This patch series adds busy detect for stm32 sdmmc variant.
Some adaptations are required:
-Avoid to check and poll busy status when is not expected.
-Clear busy status bit if busy_detect_flag and busy_detect_mask are
   different.
-Add hardware busy timeout with MMCIDATATIMER register.
