| Used to configure the pad's drive strength, which, together |
| with the slew rate, affects the maximum frequency the pad's |
| output buffer can yield. If "normal" drive strength is used, |
| the maximum frequency will be lower as per the measurements |
| found in the SoC datasheet. Note that the TRM refers to the |
| "normal" drive strength as "standard". If unspecified, the |
| default will be "normal". |

| type: string |
| description: | |
| Used to configure the pad's slew rate, which affects the |
| maximum frequency the pad's output buffer can yield ( |
| "fast" slew rate -> higher pad frequency, "slow" slew rate -> |
| lower pad frequency). Note that the TRM refers to the "fast" |
| slew rate as "standard". If unspecified, the default will be |
| "fast". |
| enum: |
| - "fast" |
| - "slow" |
