The IP101A_G_IRQ_CONF_STATUS register has bits to detect which interrupts have fired. Implement the .did_interrupt callback to let the PHY core know whether the interrupt was for this specific PHY. This is useful for debugging interrupt problems with 32-pin IP101GR PHYs where the interrupt line is shared with the RX_ERR (receive error status) signal. The default values are: - RX_ERR is enabled by default (LOW means that there is no receive error) - the PHY's interrupt line is configured "active low" by default Without any additional changes there is a flood of interrupts if the RX_ERR/INTR32 signal is configured in RX_ERR mode (which is the default). Having a did_interrupt ensures that the PHY core returns IRQ_NONE instead of endlessly triggering the PHY state machine. Additionally the kernel will report this after a while: irq 28: nobody cared (try booting with the "irqpoll" option) Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
