Hello All,

Can any one help how to remove the cd and wp pin logic from kernel.

As I am using a similar design of SABRE SD board except the cd and wp pins.

I have did the changes in u-boot and is working fine. But, I need to do the same in kernel also.

Kernel Version :: 3.14.28

Please help me .!!!

Its very simple

Find the kernel Source Code .

Navigate to the arch/<architecture type >/boot/dts

Find your board's device tree file and there keep the below settings in your usdhc block

broken-cd;
disable-wp;

Thats Its!!!
