| # NOTE: The driver supports "regulator-fixed-sync" as a specializing |
| # variant when it's known that the GPIO state change operations are |
| # isr-ok and not sleep, and both startup and off-on delays are zero. |
| # This bypasses the asynchronous onoff manager which optimizes both time |
| # and memory use. |
| # |
| # To enable this use both: |
| # compatible = "regulator-fixed-sync", "regulator-fixed"; |
| # |
