From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrew Lunn Subject: [PATCH v2 net-next 5/5] arm: vf610: zii devel b: Add support for switch interrupts Date: Sun, 16 Oct 2016 19:56:53 +0200 Message-ID: <1476640613-25365-6-git-send-email-andrew@lunn.ch> References: <1476640613-25365-1-git-send-email-andrew@lunn.ch> Cc: netdev , Vivien Didelot , Florian Fainelli , Andrew Lunn To: David Miller Return-path: Received: from vps0.lunn.ch ([178.209.37.122]:46318 "EHLO vps0.lunn.ch" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1756818AbcJPR5i (ORCPT ); Sun, 16 Oct 2016 13:57:38 -0400 In-Reply-To: <1476640613-25365-1-git-send-email-andrew@lunn.ch> Sender: netdev-owner@vger.kernel.org List-ID: The Switches use GPIO lines to indicate interrupts from two of the switches. With these interrupts in place, we can make use of the interrupt controllers within the switch to indicate when the internal PHYs generate an interrupt. Use standard PHY properties to do this.
