I am using a IMX28 processor on our custom board. I have connected a qualcom WiFi module on SSP2 interface. Here I am seeing lot of command failures on this path randomly.
I am trying to add WiFi module to the device tree. I am able to see the device getting added. I could see this log :
mmc2: new high speed SDIO card at address 0001
But this is getting removed immediately. A mmc_rescan is happening which is sending CMD7 on SSP2 which is failing because of a timeout.
Can someone help why is this failing? or is there any specific configuration that needs to be done for SSP2 other than what is being done for SSP0 & 1.
