17 | This enables GPIO support through the generic GPIO library. | |
18 | You only need to enable this, if you also want to enable | |
e849dc04 | 19 | one or more of the GPIO drivers below. |

42 | Say Y here to add some extra checks and diagnostics to GPIO calls. | |
692105b8 ML |
43 | These checks help ensure that GPIOs have been properly initialized |
44 | before they are used, and that sleeping calls are not made from | |
45 | non-sleeping contexts. They can make bitbanged serial protocols | |
a9c5fff5 DB |

53 | Say Y here to add a sysfs interface for GPIOs. | |
54 | ||
55 | This is mostly useful to work around omissions in a system's | |
56 | kernel support. Those are common in custom and semicustom | |
57 | hardware assembled using standard kernels with a minimum of | |
58 | custom patches. In those cases, userspace code may import | |
59 | a given GPIO from the kernel, if no kernel driver requested it. | |
60 | ||
61 | Kernel drivers may also request that a particular GPIO be | |
62 | exported to userspace; this can be useful when debugging. | |
