description: |
|
|
Interrupts are broken on some GPY2xx PHYs in that they keep the
|
|
interrupt line asserted 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.
