MMC standby issue for WiFI

[VishnuSankar]

my wifi peripheral is not active after the target device is going to standby.

I am using Taiyo Yuden GX8 wifi module. My target board is based on mx53 QSB.

I think the mmc1 device file which is connected to wifi is not going to standby mode. but the driver wants the peripheral to go

in standby.

I have a power down pin for the wifi which is connected to processor. I am powering down that pin when the target is going to standby.

does any one experienced this.
