For a 8 description of the deprecated integer-based GPIO interface please refer to 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 26 <function>-gpios, where <function> is the function the driver will request [all …]
