TF卡供电/检测

供电问题：

arch/arm/mach-lc186x/board-common.c

static event_dispatch card_dispatch[] = {

{23, PMIC_POWER_SDIO, 0, 3300},

{22, PMIC_POWER_SDIO, 0, 3300},

{21, PMIC_POWER_SDIO, 0, 3300},

{20, PMIC_POWER_SDIO, 0, 3300},

{19, PMIC_POWER_SDIO, 0, 3000},

{18, PMIC_POWER_SDIO, 0, 3000},

{17, PMIC_POWER_SDIO, 0, 3000},

{16, PMIC_POWER_SDIO, 0, 2800},

{15, PMIC_POWER_SDIO, 0, 2800},

{14, PMIC_POWER_SDIO, 0, 2800},

{7, PMIC_POWER_SDIO, 0, 1200},

{0, PMIC_POWER_SDIO, 0, PMIC_POWER_VOLTAGE_DISABLE},

};

上面改成2800

#if defined(CONFIG_MMC_COMIP_IOPOWER)

static event_dispatch signal_dispatch[] = {

{2, PMIC_POWER_SDIO, 1, 3300},

{1, PMIC_POWER_SDIO, 1, 1800},

{0, PMIC_POWER_SDIO, 1, PMIC_POWER_VOLTAGE_DISABLE},

};

上面改成1800

如果不要t卡检测，在config里把下面的宏去掉

CONFIG_COMIP_SDCARD_DETECT=y
