Matt LaPlante692105b2009-01-26 11:12:25 +010066 These checks help ensure that GPIOs have been properly initialized
67 before they are used, and that sleeping calls are not made from
68 non-sleeping contexts. They can make bitbanged serial protocols

78 This is mostly useful to work around omissions in a system's
79 kernel support. Those are common in custom and semicustom
80 hardware assembled using standard kernels with a minimum of
81 custom patches. In those cases, userspace code may import
82 a given GPIO from the kernel, if no kernel driver requested it.
83
84 Kernel drivers may also request that a particular GPIO be
85 exported to userspace; this can be useful when debugging.

358 modes (S3 and higher). The remaining four GPIOs are powered by
359 the Intel SCH suspend power supply. These GPIOs remain
360 active during S3. The suspend powered GPIOs can be used to wake the
361 system from the Suspend-to-RAM state.
