bcmdhd driver force rescan SDIO on Android 5 ga using IMX6 platform

mayqueen — Thu, 06 Aug 2015 03:28:36 GMT

kernel: 3.10.53

As title, I porting the bcm4339 wifi module on Android 5 GA, it works, but when I turn off the wifi and turn on again,

it cannot works, kernel message as below:

======== Card detection to remove SDIO card! ========

dummy_sdmmc: probe of mmc1:0001:1 failed with error -110

dummy_sdmmc: probe of mmc1:0001:2 failed with error -110

I think it's due to the nonremovable sdio node definition for dts file, the only way is force mmc rescan when I turn off the wifi,

but how should I do? and how to fix this issue? it's serious.

I will share this patch if anyone solve this problem.

Thanks

non-removable is used for non-removable slot (like emmc); assume always present.

For your wifi card, you can remove the non-removable setting from dtsi.
