The tuning algorithm will re-execute up to 10 times if there is no failing or passing itapdly. Due to the same issue above, add prints to the tuning algorithm to make debugging these corner-cases easier. Changes since v2: - Use do while loop instead of while in patch 1/2 - Move initialization of tuning_loop to sdhci_am654_init - Separate error path in patch 1/2 - Move struct *dev = mmc_dev() to patch 2/2 link to v1: https://lore.kernel.org/linux-mmc/20240815201542.421653-1-jm@ti.com link to v2: https://lore.kernel.org/linux-mmc/20240821192435.1619271-1-jm@ti.com Judith Mendez (2): mmc: sdhci_am654: Add retry tuning mmc: sdhci_am654: Add prints to tuning algorithm drivers/mmc/host/sdhci_am654.c | 54 +++++++++++++++++++++++++++------- 1 file changed, 43 insertions(+), 11 deletions(-) base-commit: 538076ce6b8dfe5e8e8d9d250298030f165d8457
