39 bool "Debug GPIO calls"
40 depends on DEBUG_KERNEL
42 Say Y here to add some extra checks and diagnostics to GPIO calls.
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
46 slower. The diagnostics help catch the type of setup errors
47 that are most common when setting up new platforms or boards.
50 bool "/sys/class/gpio/... (sysfs interface)"
53 Say Y here to add a sysfs interface for GPIOs.
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.
61 Kernel drivers may also request that a particular GPIO be
62 exported to userspace; this can be useful when debugging.
