mikro-bus
Vendor: Generic or vendor-independent
Description
GPIO pins exposed on Mikro BUS headers.
The Mikro BUS layout provides two headers, aligned on the opposite
edges of the board.

This binding provides a nexus mapping for 10 pins, left side pins are
numbered 0 - 5 (AN - MOSI), the right side pins are numbered 6 - 10
(PWM - SDA). The bottom 2 pins on each side are used for input voltage
and ground, they are not mapped in the nexus.
Analog - AN PWM - PWM output
Reset - RST INT - Hardware Interrupt
SPI Chip Select - CS RX - UART Receive
SPI Clock - SCK TX - UART Transmit
SPI Master Input Slave Output - MISO SCL - I2C Clock
SPI Master Output Slave Input - MOSI SDA - I2C Data
VCC-3.3V power - +3.3V +5V - VCC-5V power
Reference Ground - GND GND - Reference Ground
Board's silkscreen may vary depending on your board, but coherent with
the description above as it's according to the standard's specification.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
