- Subject: [PATCH 21/21] mmc: mtk-sd: don't ignore max-frequency from device
- tree
- commit e58e68d9 ("mmc: mtk-sd: assign plat->cfg.f_max with a correct value")
- wrongly assumed that plat->cfg.f_max is always unset at the time
- mscd_drv_probe() is run. This is not true in case max-frequency being
- defined in device tree, as it is then already set by mmc_of_parser()
- in msdc_of_to_plat().
- Only set plat->cfg.f_max to the default maximum value in case it is
- not already set to a sane value.
