Subject: [PATCH 4/4] ARM: dts: stm32: Set gpio controller also as interrupt controller
Date: Fri, 7 Apr 2017 17:10:11 +0200	[thread overview]
Message-ID: <1491577811-26989-5-git-send-email-alexandre.torgue@st.com> (raw)
In-Reply-To: <1491577811-26989-1-git-send-email-alexandre.torgue@st.com>

This patch set each gpio controller as a interrupt controller. User who
wants to use gpio as interrupt will have choice to use either "gpiolib"
interface or "common" interrupt interface.
