Subject: [PATCH v2 1/5] dt-bindings: interrupt-controller: Update STM32 EXTI interrupt controller
Date: Wed, 15 Dec 2021 11:58:43 +0100	[thread overview]
Message-ID: <20211215105847.2328-2-alexandre.torgue@foss.st.com> (raw)
In-Reply-To: <20211215105847.2328-1-alexandre.torgue@foss.st.com>

Document new entry "st,exti-mapping" which links EXTI lines with GIC
interrupt lines and add an include file to define EXTI interrupt type.

Signed-off-by: Alexandre Torgue <alexandre.torgue@foss.st.com>
