Re: [PATCH 3/4] arm64: dts: ti: k3-am62p5-sk: add out-band-wakeup property to m_can devices

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The `out-band-wakeup` property is added to the device tree but is neither parsed by any kernel C code nor documented in device tree bindings, rendering it functionally inert.

arm64: dts: ti: k3-am62p5-sk: add out-band-wakeup property to m_can devices

This commit adds the out-band-wakeup property to the mcu_mcan0 and mcu_mcan1
nodes in the k3-am62p5-sk device tree. The intent is to enable the
out_band_wakeup flag during suspend so the devices can serve as wakeup
sources from deep low-power states.

[Severity: Medium]
Is this property parsed by any driver code in the kernel?

The commit message indicates this allows the out_band_wakeup flag to be
enabled during suspend, but there does not appear to be any C code that
actually parses the out-band-wakeup property from the device tree to apply
this flag.

Without driver support to parse this, the property will remain inert. Does
this rely on a separate driver patch that is missing from this series?

Additionally, is this property documented in the device tree bindings? If
not, it will trigger dtbs_check validation errors.
