First three are small fixes to the code, next two make the clock calculation code simpler. Michał Mirosław (5): mmc: sdhci: fix base clock usage in preset value mmc: sdhci: always obey programmable clock config in preset value mmc: sdhci: fix SDHCI_QUIRK2_CLOCK_DIV_ZERO_BROKEN mmc: sdhci: move SDHCI_QUIRK2_CLOCK_DIV_ZERO_BROKEN frequency limit mmc: sdhci: simplify v2/v3+ clock calculation drivers/mmc/host/sdhci-of-arasan.c | 11 +-- drivers/mmc/host/sdhci-of-dwcmshc.c | 9 +- drivers/mmc/host/sdhci.c | 123 +++++++++++++--------------- drivers/mmc/host/sdhci.h | 4 +- 4 files changed, 68 insertions(+), 79 deletions(-)
