Subject: [PATCH v3 3/3] arm64: dts: ti: k3-am62p: use ti,am62-mcan compatible for m_can devices
Date: Sat, 12 Sep 2026 16:32:15 -0500 [thread overview]
Message-ID: <20260912-smth-v3-3-6fa661ae5a4c@ti.com> (raw)
In-Reply-To: <20260912-smth-v3-0-6fa661ae5a4c@ti.com>
Prepend "ti,am62-mcan" to the m_can device compatible property since
this compatible adds out-of-band wakeup functionality. The m_can pins
can be a wakeup source in the deepest low power states, despite being
in power domains which are OFF during deeper low power states since
it has the out-of-band wakeup capability.
