TMIO_MMC_WRPROTECT_DISABLE is equivalent to MMC_CAP2_NO_WRITE_PROTECT. The flag is propagated as follows: tmio_mmc_data::capabilities2 -> mmc_host::caps2 Only the difference is the TMIO_... makes tmio_mmc_get_ro() return 0 (i.e. it does not affect mmc_gpio_get_ro() at all), while MMC_CAP2_... returns 0 before calling ->get_ro() hook (i.e. it affects both IP own logic and GPIO detection). The TMIO MMC drivers do not set-up gpio_ro by themselves, so gpio_ro is obviously unused by legacy boards like this. So, this conversion should be safe.
