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.
