in mmc_power_up() we have: /* Try to set signal voltage to 3.3V but fall back to 1.8v or 1.2v */ if (__mmc_set_signal_voltage(host, MMC_SIGNAL_VOLTAGE_330) == 0) dev_err(mmc_dev(host), "Initial signal voltage of 3.3v\n"); else if (__mmc_set_signal_voltage(host, MMC_SIGNAL_VOLTAGE_180) == 0) dev_err(mmc_dev(host), "Initial signal voltage of 1.8v\n"); else if (__mmc_set_signal_voltage(host, MMC_SIGNAL_VOLTAGE_120) == 0) dev_err(mmc_dev(host), "Initial signal voltage of 1.2v\n"); Here one jut brutally tries to set the initial power to 3.3 but nowhere in general code there is a check if the controller can handle this w.r.t HOST CAPS. Where should this check be performed, I am guessing either here or in sdhci? This is all new to me so I am just throwing this out there Jocke-- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
