Hi,
This series adds a fix for sdhci-of-at91 driver (patch 1/2). Along with
it patch 2/2 replaces a while loop + timeout with read_poll_timeout().
Changes in v2:
- use read_poll_timeout() in patch 1/2
- add patch 2/2
Claudiu Beznea (2):
mmc: sdhci-of-at91: wait for calibration done before proceed
mmc: sdhci-of-at91: replace while loop with read_poll_timeout

Datasheet specifies that at the end of calibration the SDMMC_CALCR_EN
bit will be cleared. No commands should be send before calibration is
done.
Fixes: dbdea70f71d67 ("mmc: sdhci-of-at91: fix CALCR register being rewritten")
Fixes: 727d836a375ad ("mmc: sdhci-of-at91: add DT property to enable calibration on full reset")

Hi Nicolas,
I haven't added your tag from previous version as I changed the
implementation to use read_poll_timeout().
Thank you,
