[PATCH v6 0/2] can: m_can: introduce ti,am62-mcan compatible for out-of-band wakeup

[Kendall Willis]

This series introduces the "ti,am62-mcan" compatible which adds support
for out-of-band wakeup capability in m_can devices.

A corresponding DTS series enabling this feature on TI K3 AM62 family
of devices has been submitted separately:
"arm64: dts: ti: use ti,am62-mcan compatible for m_can devices"

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

Changes in v6:
- Fix indentation for items under the compatible property in DT
  bindings.
- Link to v5: https://lore.kernel.org/r/20260912-temp-v5-0-2e3201c02109@xxxxxx

Changes in v5:
- Rename compatible string from "ti,am62-m_can" to "ti,am62-mcan".
- Update dt binding to use "oneOf" with a fallback compatible chain instead of a flat "enum".
- Rename "struct m_can_pdata" to "struct m_can_of_data".
- Read match data at probe time and cache it in "m_can_classdev" instead of fetching it in suspend.
- Add "out_band_wakeup" flag to "struct m_can_classdev".
- Guard wakeup/sleep pinctrl selection in suspend with a return value check.
- Link to v4: https://lore.kernel.org/r/20260902-temp-v4-0-3896f7d16ce8@xxxxxx

Changes in v4:
- Remove patch for "out-band-wakeup" property in dt binding.
- Create "ti,am62-m_can" compatible in the dt binding and m_can driver.
- Add "struct m_can_of_data" for compatible-specific data which keeps track
  of "out_band_wakeup" flag.
- Replace check "out-band-wakeup" dt property in the device driver upon
  suspend with check for "out_band_wakeup" variable from the
  "m_can_of_data".
- Link to v3: https://lore.kernel.org/r/20260821-temp-v3-0-9ac1f8806929@xxxxxx

Changes in v3:
- Remove definition of "out-band-wakeup" property in dt binding.
- Allow "out-band-wakeup" property in dt binding.
- Link to v2: https://lore.kernel.org/r/20260820-temp-v2-0-dd3f8cacc15e@xxxxxx

Changes in v2:
- Create "out-band-wakeup" property in dt bindings.
- Use "out-band-wakeup" property to set the out_band_wakeup flag upon
  suspend.
- Rebase to v7.2
- Link to v1: https://lore.kernel.org/r/20260213-mcan-out-of-band-v1-1-af68d4c570b3@xxxxxx
