Subject: [PATCH v3 10/10] ARM: dts: stm32: add wakeup capability on each usart/uart on stm32mp157c
Date: Thu, 13 Jun 2019 15:50:00 +0200 [thread overview]
Message-ID: <1560433800-12255-11-git-send-email-erwan.leray@st.com> (raw)
In-Reply-To: <1560433800-12255-1-git-send-email-erwan.leray@st.com>
- Mark all usart/uart devices as wakeup source.
- Identify all dedicated interrupts with a specific interrupt name (either
"event" or "wakeup").
- add interrupts-extended wakeup interrupt
