Hi,
I am trying to enable the configuration to include the DCM driver in the kernel and compile image for the board LS1021, but i am getting the compilation error as :
"| drivers/misc/fsl_dcm.c: In function 'write_sram':
| drivers/misc/fsl_dcm.c:83:2: error: implicit declaration of function 'out_8' [-Werror=implicit-function-declaration]
| out_8(dcm->addr, offset);
| ^
| drivers/misc/fsl_dcm.c: In function 'read_sram':
| drivers/misc/fsl_dcm.c:94:2: error: implicit declaration of function 'in_8' [-Werror=implicit-function-declaration]
| return in_8(dcm->data);
| ^".
Please provide inputs how to resolve this issue.
Implicit declaration means the compiler detected this function usage in your code, but the function is not declared yet.
This is not a mistake, if the function is declared later. If this function is never declared, there should be an error reported.
Have a great day,
Alexander
