Subject: [PATCH 0/3] macb add support for phy gpio interrupt
Main feature of this patch set is phy gpio interrupt for macb.
There is a couple of concerns about this patch series.
* PHY interrupt support has never been supported with macb before but many board have set phy_irq_pin variable. These board will be swapped over to interrupt handing now and while this should work but one can never be 100% certain.
* at91_ether driver supported interrupt on some PHYs which does not have PHY drivers in phylib or doesn't have interrupt support hooked up.
Patch 1 add interrupt handing to a couple of Davicom PHY that is used on most (all?) Atmel eval boards and was also popular on custom boards.
If the 2nd patch breaks any boards there are 2 possible ways to fix the issue. One would be to go back to polling by setting phy_irq_pin to EINVAL. The other would be add a proper PHY driver with interrupt support for the PHY in question.
I would be grateful if anyone can test the 2 first patches on any AT91 boards that they might have access to. If there is any breakage I am more than willing to help out.
Patch series was tested on a custom board with DM9161AEP and AT91RM9200 EMAC.
Last patch in this series is unrelated to the phy stuff. It's is a small fix for macb hw set addr functions when used in at91_ether.
Joachim Eastwood (3):
net/phy/davicom: add irq functions to DM9161E and DM9161A
net/macb: add support for phy irq via gpio pin
net/macb: clear unused address register
