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.

pinctrl-0

phandles

 
PIO pin configuration for Timer Counter 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 TC0 on SAME7x would be
   pinctrl-0 = <&pa0b_tc0_tioa0 &pa1b_tc0_tiob0>;
