[PATCH v3 3/3] arm64: dts: ti: k3-am62p: use ti,am62-mcan compatible for m_can devices
From: Kendall Willis
Date: Sat Sep 12 2026 - 17:32:39 EST
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.
