Subject: [PATCH v3 1/2] irqchip/stm32: Add irq retrigger support
Date: Wed, 19 Feb 2020 15:32:28 +0100	[thread overview]
Message-ID: <20200219143229.18084-2-alexandre.torgue@st.com> (raw)
In-Reply-To: <20200219143229.18084-1-alexandre.torgue@st.com>

This commit introduces retrigger support for stm32_ext_h chip.
It consists to rise the GIC interrupt mapped to an EXTI line.

Signed-off-by: Alexandre Torgue <alexandre.torgue@st.com>
Tested-by: Marek Vasut <marex@denx.de>
