Description

GPIO pins exposed on micromod headers.

The micromod standard leverages the M.2 connector with 76 pins for
swap between a myriad of supported boards and carriers.

The micromod standard consists of two lanes with the following
supported buses:
* An 6-pin Power Supply header.  No pins on this header are exposed
  by this binding.
* Reset, Boot pins and SWD pins not exposed by this binding.
* 2 UART buses. First with RTS and CTS pins, while the 2nd with only
RX and TX pins. Neither of them are exposed by this binding.
* 2 i2c buses. Only the corresponding interrupt pin is exposed by
this binding.
* 2 SPI buses not exposed by this binding. Only SPI CS control pin
  is exposed by this binding.
* Audio line not exposed by this binding.
* 2 analog pins (A0 and A1).
* 2 digital pins (D0 and D1).
* 12 General purpose pins (G0 - G11).

This binding provides a nexus mapping for the analog, digital and
general purpose gpios in the order depicted below:

  - 00 -> A0                      PIN 34
  - 01 -> A1                      PIN 38
  - 02 -> D0                      PIN 10
  - 03 -> D1/CAM_TRIG             PIN 18
  - 04 -> I2C_INT#                PIN 16
  - 05 -> G0/BUS0                 PIN 40
  - 06 -> G1/BUS1                 PIN 42
  - 07 -> G2/BUS2                 PIN 44
  - 08 -> G3/BUS3                 PIN 46
  - 09 -> G4/BUS4                 PIN 48
  - 10 -> G5/BUS5                 PIN 73
  - 11 -> G6/BUS6                 PIN 71
  - 12 -> G7/BUS7                 PIN 69
  - 13 -> G8                      PIN 67
  - 14 -> G9/ADC_D-/CAM_HSYNC     PIN 65
  - 15 -> G10/ADC_D+/CAM_VSYNC    PIN 63
  - 16 -> G11/SWO                 PIN  8
  - 17 -> SPI_CS                  PIN 55

zephyr,deferred-init

boolean

 
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().

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.

zephyr,pm-device-runtime-auto

boolean

 
Automatically configure the device for runtime power management after the
init function runs.

zephyr,disabling-power-states

phandles

 
List of power states that will disable this device power.
