 |     Test pin controller pin configuration nodes. Each node is composed by one or |

 |       Test pin controller pin configuration group. Each group contains a list of | 
 |       pins sharing the same set of properties. Example: | 
 |  | 
 |       /* node representing default state for test_device0 */ | 
 |       test_device0_default: test_device0_default { | 
 |         /* group 1 (name is arbitrary) */ | 
 |         group1 { | 
 |           /* configure pins 0 and 1 */ | 
 |           pins = <0>, <1>; | 
 |           /* both pins 0 and 1 have pull-up enabled */ | 
 |           bias-pull-up; | 
 |         }; | 
 |         ... | 
 |         /* group N (name is arbitrary) */ | 
 |         groupN { | 
 |           /* configure pin M */ | 
 |           pins = <M>; | 
 |           /* pin M has pull-down enabled */ | 
 |           bias-pull-down; | 
 |         }; | 
 |       }; |

 |       The list of supported standard properties: | 
 |  | 
 |       - bias-pull-up: Enable pull-up resistor. | 
 |       - bias-pull-down: Enable pull-down resistor. |

 |         description: | | 
 |           An array of pins sharing the same group properties. Each entry is a | 
 |           32-bit integer that is just used to identify the entry for testing | 
 |           purposes. |
