adafruit-feather-header¶

Vendor: Generic or vendor-independent

Description¶

GPIO pins exposed on Adafruit Feather headers.

The Feather layout provides two headers, one each along
opposite edges of the board.
Proceeding counter-clockwise:
* A 16-pin header.  12 pins on this header are exposed
  by this binding.
* A 12-pin header.  9 pins on this header are exposed
  by this binding.

This binding provides a nexus mapping for 21 pins where parent pins 0
through 5 correspond to A0 through A5, and parent pins 6 through 20
correspond as depicted below:

    - RESET
    - 3V3
    - 3V3
    - GND
    0 A0                     - VBAT
    1 A1                     - EN
    2 A2                     - VBUS
    3 A3                     D13  20
    4 A4                     D12  19
    5 A5                     D11  18
    6 SCK                    D10  17
    7 MOSI                   D9   16
    8 MISO                   D6   15
    9 RX                     D5   14
   10 TX                     SCL  13
   11 D4                     SDA  12

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`gpio-map`	`compound`	This property is required.
`gpio-map-mask`	`compound`
`gpio-map-pass-thru`	`compound`
`#gpio-cells`	`int`	Number of items to expect in a GPIO specifier This property is required.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “adafruit-feather-header” compatible.

Name	Type	Details
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.
