Wifi/BT interface not detected

@aithal 
IMHO the messages you published do not explain why you have no WiFi/BT.
No offense intended, but have you checked the dip switches?

 
Yes the kill switch is in right position. The WIFI module has stopped all of a sudden.
 After browsing through internet for few days now.. I see the mmc1 is not being detected and so the rtl8723cs driver is not loading.

On phones where WIFI module is working the mmc1 is detected - mmcX new high speed SDIO card at address 0001 .

On my phone I dont see this happening.

The device tree output from my device :-

Code:

SDIO detection not returning anything

Code:

grep sdio_pins device_tree.out

grep -E "mmc[0-2]|mmc@" device_tree.out
        ethernet0 = "/soc/mmc@1c10000/wifi@1";
        mmc@1c0f000 {
        mmc@1c10000 {
        mmc@1c11000 {
            mmc0-pins {
                function = "mmc0";
            mmc1-pins {
                function = "mmc1";
            mmc2-ds-pin {
                function = "mmc2";
            mmc2-pins {
                function = "mmc2";

If someone can help with the devicetree output from a working device it will be helpful in identifying the issue. I dont see sdio pins defined in my device tree (I see it on my home raspberry pi). I'm a novice in kernel stuffs, so kernel developers please help in debugging this issue.. Thank you
