cd and wp remove from kernel

[venkatachilakal]

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!!!
