mmc: sdhci_am654: Fix conditions for enabling dll (fe52e2fb) · Commits · 戴 / test

The clock > CLOCK_TOO_SLOW_HZ condition gating phy configuration is only required because dll should not be enabled at too low a clock frequency or too low timing. Make sure that this condition only gates dll enablement. Signed-off-by:
