Subject: [PATCH 1/4] arm64: dts: ti: k3-am62-lp-sk: add out-band-wakeup property to m_can devices
Date: Thu, 20 Aug 2026 17:08:51 -0500	[thread overview]
Message-ID: <20260820-smth-v1-1-e1738a38d58e@ti.com> (raw)
In-Reply-To: <20260820-smth-v1-0-e1738a38d58e@ti.com>

The m_can pins can be a wakeup source in the deepest low power states,
despite being in the MCU domain which is OFF during deeper low power
states. Add the out-band-wakeup property to allow the out_band_wakeup flag
to be enabled during suspend for m_can devices.
