| 18 | description: | |
| 19 | Interrupts are broken on some GPY2xx PHYs in that they keep the |
| 20 | interrupt line asserted for a random amount of time even after the |
| 21 | interrupt status register is cleared. Thus it is blocking the |
| 22 | interrupt line which is usually bad for shared lines. By default, |
| 23 | interrupts are disabled for this PHY and polling mode is used. If one |
| 24 | can live with the consequences, this property can be used to enable |
| 25 | interrupt handling. |
| 26 | |
| 27 | Affected PHYs (as far as known) are GPY215B and GPY215C. |
