atmel,sam-ssc

Vendor: Atmel Corporation

Description

Atmel SAM SSC (Synchronous Serial Controller) controller

Properties

Node specific properties

Base properties

Properties not inherited from the base binding file.

Name

Type

Details

peripheral-id

int

 
peripheral ID

This property is required.

pinctrl-0

phandles

 
PIO pin configuration for RF, RK, RD, TF, TK, & TD signals.
We expect that the phandles will reference pinctrl nodes.
These nodes will have a nodelabel that matches the Atmel SoC HAL
defines and be of the form p<port><pin><periph>_<inst>_<signal>.

For example the SSC on SAME7x would be
   pinctrl-0 = <&pd24b_ssc_rf &pa22a_ssc_rk &pa10c_ssc_rd
                &pb0d_ssc_tf &pb1d_ssc_tk &pb5d_ssc_td>;

This property is required.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “atmel,sam-ssc” compatible.

Name

reg

array

 
register space

This property is required.

See Important properties for more information.

interrupts

array

 
interrupts for device

This property is required.

See Important properties for more information.

dmas

phandle-array

 
TX & RX dma specifiers.  Each specifier will have a phandle
reference to the dma controller, the channel number, and peripheral
trigger source.

For example dmas for TX, RX would look like
   dmas = <&xdmac 22 DMA_PERID_SSC_TX>, <&xdmac 23 DMA_PERID_SSC_RX>;

This property is required.

dma-names

string-array

 
This should be "tx" and "rx" to match the dmas property.

For example
   dma-names = "tx", "rx";

This property is required.

status

string

 
indicates the operational status of a device

Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss'

See Important properties for more information.

compatible

string-array

 
compatible strings

This property is required.

See Important properties for more information.

reg-names

string-array

 
name of each register space

interrupts-extended

compound

 
extended interrupt specifier for device

interrupt-names

string-array

 
name of each interrupt

interrupt-parent

phandle

 
phandle to interrupt controller node

label

string

 
Human readable string describing the device (used as device_get_binding() argument)

See Important properties for more information.

clocks

phandle-array

 
Clock gate information

clock-names

string-array

 
name of each clock

#address-cells

int

 
number of address cells in reg property

#size-cells

int

 
number of size cells in reg property

io-channels

phandle-array

 
IO channels specifiers

io-channel-names

string-array

 
Provided names of IO channel specifiers
