Merge tag 'mmc-v4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc
Pull MMC fixes from Ulf Hansson: - meson-gx: Revert to earlier tuning process - bcm2835: Don't overwrite max frequency unconditionally * tag 'mmc-v4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: mmc: bcm2835: Don't overwrite max frequency unconditionally Revert "mmc: meson-gx: include tx phase in the tuning process"
