Module Name:    src
Committed By:   jakllsch

Modified Files:
        src/sys/dev/sdmmc: sdhc.c

Log Message:
Add support for SDHCI 3.0 bus clock generation, which unlike 1.0 and 2.0
has support for non-power-of-two divisors from 1 to 1023. Additionally
restore finding the correct power-of-two divisor for standard-compliant
pre-3.0 SDHCI parts.  Also, calculate minimum divided clock for the
clkmsk-quirk parts correctly.

XXX Will future standard-compliant SDHCI versions have a SDHCI 3.0
backwards-compatible clock generator, or just SDHCI 1.0/2.0?
