In current kernel mmc driver, it uses two 'msleep(10)'
for eMMC/SD card power up ramp up time delay.
According to Spec, the ramp up time should be max of 74
eMMC/SD bus clock or 1ms.
Take the worst eMMC/SD card I can image as the example -
assume it has to work on 32KHz or 16KHz during the card in
From: "Zhang, YiX X"
Current sysfs output format for eMMC Enhanced Area feature
are incorrect.
If the enhanced area feature not enabled, then the driver
will return error code -EINVAL(-22) as the sysfs value.
But the definition for those two sysfs items are
