[PATCH] mmc: core: Wait for Vdd to settle on card power off

2017-09-21 Thread Kyle Roeschley
The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be lowered to less than 0.5V for a minimum of 1 ms when powering off a card. Increase our wait to 10 ms so that voltage has time to drain down to 0.5V and cards can power off correctly. Signed-off-by: Kyle Roeschley --- drivers/mmc/c
