7 bool "GPIO Support"
9 This enables GPIO support through the generic GPIO library.
11 one or more of the GPIO drivers below.
47 this symbol, but new drivers should use the generic gpio-regmap
51 bool "Debug GPIO calls"
54 Say Y here to add some extra checks and diagnostics to GPIO calls.
57 non-sleeping contexts. They can make bitbanged serial protocols
