Dboard.rst5 This document explains how GPIOs can be assigned to given devices and functions.
7 Note that it only applies to the new descriptor-based interface. For a
8 description of the deprecated integer-based GPIO interface please refer to
9 gpio-legacy.txt (actually, there is no real mapping possible with the old
15 Kconfig. Then, how GPIOs are mapped depends on what the platform uses to
17 tree, ACPI, and platform data.
20 -----------
21 GPIOs can easily be mapped to devices and functions in the device tree. The
22 exact way to do it depends on the GPIO controller providing the GPIOs, see the
25 GPIOs mappings are defined in the consumer device's node, in a property named

21 System-on-Chip (SOC) processors heavily rely on GPIOs. In some cases, every
22 non-dedicated pin can be configured as a GPIO; and most chips have at least
