Vendor: Atmel Corporation

Description

Atmel SAM Timer Counter (TC) node

Properties

Properties not inherited from the base binding file.

Name

Type

Details

peripheral-id

array

peripheral ID

This property is required.

channel

int

Timer / Counter channel to use, channel 0 is the default.
Valid range: 0 - 2

clk

int

Clock source selection as defined by TCCLKS bit-field of TC_CMR
register. Consult the datasheet for the details.

nodivclk

boolean

If set to true the `clk` property is ignored. Instead the TC module is
driven directly via MCLK. Only supported on sam4e, same70, same70b,
samv71, samv71b SoC series.

reg-cmr

int

Alternate value of the CMR (Channel Mode Register) register.
If specified this value will be written to the register during driver
instance initialization instead of the default. It can be used to
configure the timer / counter in the custom mode. Together with other
properties like channel-num, pinctrl-0 this allows e.g. to configure
the driver to count events generated on the TIOA, TIOB signal connected
to the external pin.

reg-rc

int

Register C compare/match value. RC can be used as compare/match unit
for an specific timer unit. Their use depends on how timer channel
is configured,see reg-cmr. It can be used as trigger for both input
capture or counter mode, or even as event source. The RC register
behavior is SoC dependent. For more information and use cases,
check SoC datasheet and application notes.

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

pinctrl-1

phandles

Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

Pin configuration/s for the fifth state. See pinctrl-0.

pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.

Deprecated properties not inherited from the base binding file.

(None)

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-tc” compatible.

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.

label

string

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

This property is required.

See Important properties for more information.

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

clocks

phandle-array

Clock gate information

clock-names

string-array

name of each clock

#address-cells

int

number of address cells in reg property

int

number of size cells in reg property

dmas

phandle-array

DMA channels specifiers

dma-names

string-array

Provided names of DMA channel specifiers

io-channels

phandle-array

IO channels specifiers

io-channel-names

string-array

Provided names of IO channel specifiers

mboxes

phandle-array

mailbox / IPM channels specifiers

mbox-names

string-array

Provided names of mailbox / IPM channel specifiers

wakeup-source

boolean

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.

power-domain

phandle

Power domain the device belongs to.

The device will be notified when the power domain it belongs to is either
suspended or resumed.
