tiac-magpie-pin-header
Vendor: Generic or vendor-independent
Description
GPIO pins exposed on TiaC MAGPIE headers.
The TiaC Magpie layout provides five headers, each two rows with
seven pins per row.
This binding provides a nexus mapping for 12 pins for each header,
left side pins are the odd pins numbered 0, 2, 4, 6, 8, 10, the right
side pins are the even pins numbered 1, 3, 5, 7, 9, 11. The bottom pins
on each side are used for ground, they are not mapped in the nexus.
(GPIOx/1) TMPHx/1 1 --o o-- 2 TMPHx/2 (GPIOx/2)
(GPIOx/3) TMPHx/3 3 --o o-- 4 TMPHx/4 (GPIOx/4)
(GPIOx/5) TMPHx/5 5 --o o-- 6 TMPHx/6 (GPIOx/6)
(GPIOx/7) TMPHx/7 7 --o o-- 8 TMPHx/8 (GPIOx/8)
(GPIOx/9) TMPHx/9 9 --o o-- 10 TMPHx/10 (GPIOx/10)
(GPIOx/12) TMPHx/11 11 --o o-- 12 TMPHx/12 (GPIOx/12)
(GND) 13 --o o-- 14 (GND)
Board's silkscreen may vary depending your board, but coherent with the
description above as it's according to the standard's specification.
Not every TiaC board provides all five headers.

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.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.

|
indicates the operational status of a device
