Microchip TCC G1 counter peripheral.
Microchip TCC G1 counter peripheral.
This driver is used for configuring and managing TCC
(Timer/Counter for Control Applications) peripheral in Microchip microcontrollers.
This peripherals support counting events, measuring time intervals, and generating
periodic interrupts.
The supported peripheral IP versions :
- TCC id="U2213" version="3.1.0"
The supported families are:
- SAM_E5X_D5X

Timer prescaler values.
The prescaler divides the input clock frequency to
achieve the desired timer frequency.
Legal values: |
|
|
This specifies the maximum number of channels available for the peripheral instance.
This property is required. |
|
|
Maximum bit width supported by the counter.
This property specifies the resolution of the counter. The value provided in the device tree
should reflect the maximum supported by the hardware instance. It should only be overridden
after consulting the relevant family datasheet to ensure compatibility.
This property is required. Legal values: |
|
|
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
|
|
|
Pin configuration/s for the second state. See pinctrl-0.
|
|
|
Pin configuration/s for the third state. See pinctrl-0.
|
|
|
Pin configuration/s for the fourth state. See pinctrl-0.
|
|
|
Pin configuration/s for the fifth state. See pinctrl-0.
|
|
|
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 “microchip,tcc-g1-counter” compatible.

|
Specifies the base address and size of the register set for the timer counter peripheral.
This property is required. See Important properties for more information. |
|
|
Defines the interrupt lines used by the timer counter peripheral.
This property specifies the interrupt number and priority.
This property is required. See Important properties for more information. |
|
|
Specifies the clock sources and their configurations for the timer counter peripheral.
This property ensures the peripheral is provided with the necessary clock signals.
This property is required. |
|
|
Indicates the operational status of the hardware or other
resource that the node represents. In particular:
- "okay" means the resource is operational and, for example,
can be used by device drivers
- "disabled" means the resource is not operational and the system
should treat it as if it is not present
For details, see "2.3.4 status" in Devicetree Specification v0.4.
Legal values: See Important properties for more information. |

This property is a list of strings that essentially define what
type of hardware or other resource this devicetree node
represents. Each device driver checks for specific compatible
property values to find the devicetree nodes that represent
resources that the driver should manage.
The recommended format is "vendor,device", The "vendor" part is
an abbreviated name of the vendor. The "device" is usually from
the datasheet.
The compatible property can have multiple values, ordered from
most- to least-specific. Having additional values is useful when the
device is a specific instance of a more general family, to allow the
system to match the most specific driver available.
For details, see "2.3.1 compatible" in Devicetree Specification v0.4.
This property is required. See Important properties for more information. |

Optional names given to each register block in the "reg" property.
For example:
/ {
soc {
#address-cells = <1>;
#size-cells = <1>;
uart@1000 {
reg = <0x1000 0x2000>, <0x3000 0x4000>;
reg-names = "foo", "bar";
};
};
};
The uart@1000 node has two register blocks:
- one with base address 0x1000, size 0x2000, and name "foo"
- another with base address 0x3000, size 0x4000, and name "bar"

|
Extended interrupt specifier for device, used as an alternative to
the "interrupts" property.
For details, see "2.4 Interrupts and Interrupt Mapping" in
Devicetree Specification v0.4.
|
|
|
Optional names given to each interrupt generated by a device.
The interrupts themselves are defined in either "interrupts" or
"interrupts-extended" properties.
For details, see "2.4 Interrupts and Interrupt Mapping" in
Devicetree Specification v0.4.
|
|
|
If present, this refers to the node which handles interrupts generated
by this device.
For details, see "2.4 Interrupts and Interrupt Mapping" in
Devicetree Specification v0.4.
|
|
|
Human readable string describing the device. Use of this property is
deprecated except as needed on a case-by-case basis.
For details, see "4.1.2 Miscellaneous Properties" in Devicetree
Specification v0.4.
See Important properties for more information. |
|
|
Optional names given to each clock provider in the "clocks" property.
|
|
|
This property encodes the number of <u32> cells used by address fields
in "reg" properties in this node's children.
For details, see "2.3.5 #address-cells and #size-cells" in Devicetree
Specification v0.4.
|
|
|
This property encodes the number of <u32> cells used by size fields in
"reg" properties in this node's children.
For details, see "2.3.5 #address-cells and #size-cells" in Devicetree
Specification v0.4.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
