[PATCH 0/4] arm64: dts: ti: add out-band-wakeup property to m_can devices

[Kendall Willis]

This series adds out-of-band wakeup support for the m_can devices in the
device tree of AM62X-LP, AM62A, AM62D, and AM62P SoCs by integrating
the out-band-wakeup property.

Dependency
----------
This series depends on the "can: m_can: support out-of-band wakeup
capability" series which implements the out-of-band wakeup support in
the m_can driver and dt bindings.

Testing
-------
Tested suspend/resume with CAN wakeup on AM62P SK EVM.

[PATCH 1/4] arm64: dts: ti: k3-am62-lp-sk: add out-band-wakeup property to m_can devices

[Kendall Willis]

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.

Additional dependency on PR in dt-schema repository that defines the
"out-band-wakeup" property:

In updated series of mcan[0]
LTM, you want to decide out-band-wakeup by compatible.
If so then, this series can be dropped.

Yep, this series should be dropped, I will be continuing with the series
