| 67 This is mostly useful to work around omissions in a system's 68 kernel support. Those are common in custom and semicustom 69 hardware assembled using standard kernels with a minimum of 70 custom patches. In those cases, userspace code may import 71 a given GPIO from the kernel, if no kernel driver requested it. | 67 This ABI is deprecated. If you want to use GPIO from userspace, 68 use the character device /dev/gpiochipN with the appropriate 69 ioctl() operations instead. The character device is always 70 available. |

| 73 Kernel drivers may also request that a particular GPIO be 74 exported to userspace; this can be useful when debugging. 75 | |
