PIO pin configuration for TWCK & TWD 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 I2C on SAM3x would be
|
|
pinctrl-0 = <&pa18a_twi0_twck0 &pa17a_twi0_twd0>;
