4 This document explains how GPIOs can be assigned to given devices and functions.
12 is mandatory) or ARCH_WANT_OPTIONAL_GPIOLIB (if GPIO support can be omitted) in
14 describe its hardware layout. Currently, mappings can be defined through device
19 GPIOs can easily be mapped to devices and functions in the device tree. The
48 The led GPIOs will be active-high, while the power GPIO will be active-low (i.e.
49 gpiod_is_active_low(power) will be true).
54 The above DT example can be converted to an equivalent ACPI description
93 Finally, GPIOs can be bound to devices and functions using platform data. Board
109 can be NULL, in which case it will be matched for calls to gpiod_get()
112 can be NULL, in which case it will match any function.
119 In the future, these flags might be extended to support more properties.
123 A lookup table can then be defined as follows, with an empty entry defining its
137 And the table can be added by the board code as follows:
141 The driver controlling "foo.0" will then be able to obtain its GPIOs as follows:
152 Since the "power" GPIO is mapped as active-low, its actual signal will be 0
