Subject: [PATCH 5/6] ARM: dts: stm32: add RTC LSCO support on stm32mp157c-dk2
Date: Wed, 4 May 2022 15:06:16 +0200 [thread overview]
Message-ID: <20220504130617.331290-4-valentin.caron@foss.st.com> (raw)
In-Reply-To: <20220504130233.330983-1-valentin.caron@foss.st.com>
From: Gabriel Fernandez <gabriel.fernandez@foss.st.com>
Add LSCO support on stm32mp157c-dk2 board. LSCO output is mapped on
RTC_OUT2_RMP (PI8), directly routed on LPO_IN pin of Wifi/Bluetooth
module.
