STMicroelectronics SSC (SPI) Controller
|
||
|
|
---------------------------------------
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : "st,comms-ssc4-spi"
|
||
|
|
- reg : Offset and length of the device's register set
|
||
|
|
- interrupts : The interrupt specifier
|
||
|
|
- clock-names : Must contain "ssc"
|
||
|
|
- clocks : Must contain an entry for each name in clock-names
|
||
|
|
See ../clk/*
|
||
|
|
- pinctrl-names : Uses "default", can use "sleep" if provided
|
||
|
|
See ../pinctrl/pinctrl-binding.txt
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- cs-gpios : List of GPIO chip selects
|
||
|
|
See ../spi/spi-bus.txt
|
||
|
|
|
||
|
|
Child nodes represent devices on the SPI bus
