8 | Selecting this config option from the architecture Kconfig allows | |
9 | the architecture to provide a custom asm/gpio.h implementation | |
10 | overriding the default implementations. New uses of this are | |

e849dc04 | 19 | one or more of the GPIO drivers below. |

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

58 | ||
59 | This is mostly useful to work around omissions in a system's | |
60 | kernel support. Those are common in custom and semicustom | |
61 | hardware assembled using standard kernels with a minimum of | |
62 | custom patches. In those cases, userspace code may import | |
63 | a given GPIO from the kernel, if no kernel driver requested it. | |
64 | ||
65 | Kernel drivers may also request that a particular GPIO be | |
66 | exported to userspace; this can be useful when debugging. | |
