From 702d211c45d95e6788cec42f7f3c4a538e8853ef Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Fri, 27 Feb 2015 09:58:29 +0100 Subject: [PATCH] at86rf230: add irq low-level for polarity The at86rf2xx chips supports the setting of irq polarity if active low or active high. This patch adds a handling for IRQ_ACTIVE_LOW if the irq_type is IRQ_TYPE_LEVEL_LOW.
