ti,boosterpack-header¶

Vendor: Texas Instruments

Description¶

TI BoosterPack GPIO header

GPIO pins exposed as BoosterPack headers on TI LaunchPads.

BoosterPack plug-in modules are available in 20 and 40 pin variants. The
20 pin variant has two 10 x 1 pin headers and the 40 pin variant has two
10 x 2 pin headers. Both variants are compatible and stackable.

The pins of the 20 pin variant and the outer row of the 40 pin variant are
numbered 1 through 20. The inner rows of the 40 pin variant are numbered 21
through 40. The BoosterPack pinout is depicted below:

1  3.3V     21 5V                    40 GPIO 20 GND
2  Analog   22 GND                   39 GPIO 19 GPIO / SPI CS
3  UART RXD 23 Analog                38 GPIO 18 GPIO
4  UART TXD 24 Analog                37 GPIO 17 GPIO
5  GPIO     25 Analog                36 GPIO 16 RESET
6  Analog   26 Analog                35 GPIO 15 SPI MOSI
7  SPI CLK  27 Analog                34 GPIO 14 SPI MISO
8  GPIO     28 Analog                33 GPIO 13 GPIO / SPI CS
9  I2C SCL  29                       32 GPIO 12 GPIO / SPI CS
10 I2C SDA  30                       31 GPIO 11 GPIO

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 “ti,boosterpack-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.
