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
