nxp,kinetis-lptmr

Vendor: NXP Semiconductors N.V.

Note

An implementation of a driver matching this compatible is available in drivers/counter/counter_mcux_lptmr.c.

Description

Deprecated compatible for NXP LPTMR

Properties

Node specific properties

Properties not inherited from the base binding file.

Name

Type

Details

clock-frequency

int

Counter clock frequency

This property is required.

prescaler

int

The frequency of the counter is divided by this value.

This property is required.

clk-source

int

Selects the clock to be used by the LPMTR prescaler/glitch filter.
In time counter mode, this field selects the input clock to the prescaler.
In pulse counter mode, this field selects the input clock to the glitch filter.
The clock connections vary by device, see the device reference manual for
more details.

This property is required.

Legal values: 0, 1, 2, 3

input-pin

int

When LPTMR is in Pulse mode, this value
will be used to determine the "rising-edge
source pin" to increment the lptmr counter.

active-low

boolean

When LPTMR is in Pulse mode, this value
will set the counter to active low.

resolution

int

Represents the width of the counter in bits.

This property is required.

prescale-glitch-filter

int

When in prescaler mode, the counter is incremented every
  2 ^ [prescaler-glitch-filter] clock cycles.
When in pulse mode, the counter is incremented every
  2 ^ [prescaler-glitch-filter] rising edges detected
  by the pin configured from the input-pin value.
  Note, that the pulse mode cannot be 2 ^ 16.

Default value: 1

Legal values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16

timer-mode-sel

int

This value determines rather the LPTMR is configured
for Time-Counter mode or for Pulse mode.
0 <- LPTMR is configured for Time Counter Mode.
1 <- LPTMR is configured for Pulse Mode.

Legal values: 0, 1

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

Base properties

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 “nxp,kinetis-lptmr” compatible.

Name

Type

Details

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.

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.

This property is deprecated.

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

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

power-domains

phandle-array

Power domain specifiers

power-domain-names

string-array

Provided names of power domain specifiers

#power-domain-cells

int

Number of cells in power-domains property

zephyr,deferred-init

boolean

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().

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.

zephyr,pm-device-runtime-auto

boolean

Automatically configure the device for runtime power management after the
init function runs.

zephyr,disabling-power-states

phandles

List of power states that will disable this device power.
