SPI-GPIO devicetree bindings



This represents a group of 3-n GPIO lines used for bit-banged SPI on dedicated

GPIO lines.



Required properties:



 - compatible: should be set to "spi-gpio"

 - #address-cells: should be set to <0x1>

 - ranges

 - gpio-sck: GPIO spec for the SCK line to use

 - gpio-miso: GPIO spec for the MISO line to use

 - gpio-mosi: GPIO spec for the MOSI line to use

 - sck-gpios: GPIO spec for the SCK line to use

 - miso-gpios: GPIO spec for the MISO line to use

 - mosi-gpios: GPIO spec for the MOSI line to use

 - cs-gpios: GPIOs to use for chipselect lines.

             Not needed if num-chipselects = <0>.

 - num-chipselects: Number of chipselect lines. Should be <0> if a single device

                    with no chip select is connected.



Deprecated bindings:



These legacy GPIO line bindings can alternatively be used to define the

GPIO lines used, they should not be used in new device trees.



 - gpio-sck: GPIO spec for the SCK line to use

 - gpio-miso: GPIO spec for the MISO line to use

 - gpio-mosi: GPIO spec for the MOSI line to use
