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-bindings.txt |
|
|
|
Optional properties: |
|
- cs-gpios : List of GPIO chip selects |
|
See ../spi/spi-bus.txt |
|
|
|
Child nodes represent devices on the SPI bus |
|
See ../spi/spi-bus.txt |

Example: |
|
spi@9840000 { |
|
compatible = "st,comms-ssc4-spi"; |

clocks = <&clk_s_c0_flexgen CLK_EXT2F_A9>; |
|
clock-names = "ssc"; |
|
pinctrl-0 = <&pinctrl_spi0_default>; |
|
pinctrl-names = "default"; |
|
cs-gpios = <&pio17 5 0>; |
|
#address-cells = <1>; |
