description: |
|
|
|
|
|
Interrupts are broken on some GPY2xx PHYs in that they keep the
|
2023-10-24 12:59:35 +02:00
|
|
|
interrupt line asserted for a random amount of time even after the
|
|
|
|
|
interrupt status register is cleared. Thus it is blocking the
|
|
|
|
|
interrupt line which is usually bad for shared lines. By default,
|
|
|
|
|
interrupts are disabled for this PHY and polling mode is used. If one
|
|
|
|
|
can live with the consequences, this property can be used to enable
|
|
|
|
|
interrupt handling.

Affected PHYs (as far as known) are GPY215B and GPY215C.
