The MMC framework in U-Boot does not support a systematic API for timing switch like mmc_set_timing() in Linux. U-Boot just provides a hook to change the clock frequency via mmc_set_clock(). It is up to drivers if additional register settings are needed. This driver needs to set a correct timing mode into a register when it migrates to a different speed mode. Only increasing clock frequency could result in setup/hold timing violation. The timing mode should be decided by checking MMC_TIMING_* like drivers/mmc/host/sdhci-cadence.c in Linux, but "timing" is not supported by U-Boot for now. Just use mmc->clock to decide the timing mode. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> |
