I have to access gpio pin 47 to glow LED on microzed board.
can i access this pin using the function: gpio_direction_output(unsigned gpio, int value)
If possible, In which file can i include above function?
What other functions are required other than gpio_direction_output?
I want my LED glow after kernel boots and i want it from kernel space and not from users space
Please help me.
