| 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>; |
