Hello All:


As title, Because I want to decrease power consumption when OS entering sleep mode,


my EMMC vendor is Kinston 4G size, their EMMC support sleep mode.


I trying to modify source code as following:


static const struct esdhc_platform_data mx6q_sabresd_sd4_data __initconst = {

    .always_present = 1,

    .keep_power_at_suspend = 0,

    .support_8bit = 1,

    .delay_line = 0,

    .cd_type = ESDHC_CD_PERMANENT,



but the power consumption still no decrease.


so what can I do to decrease EMMC suspend power consumption?


Thanks a lot!
