[PATCH v3] dt-bindings: hwmon: ti,tmp401: add #thermal-sensor-cells

[PATCH v3] dt-bindings: hwmon: ti,tmp401: add #thermal-sensor-cells

[Vincent Jardin via B4 Relay]

From: Vincent Jardin <vjardin@free.fr>

Since commit
  a3b61ba2558e ("hwmon: (tmp401) register with thermal subsystem")
the driver sets HWMON_C_REGISTER_TZ, so the hwmon core calls
devm_thermal_of_zone_register() for every temperature channel and the
device can be referenced as a thermal sensor.

Signed-off-by: Vincent Jardin <vjardin@free.fr>

Changes in v3:
- Rewrite the commit message: justify the property from the driver,
  which sets HWMON_C_REGISTER_TZ since a3b61ba2558e
  (Krzysztof Kozlowski)
- Keep "const: 1": every chip in this binding has at least two
  temperature channels, see national,lm90.yaml
- No change to the diff/code
- Link to v2: https://lore.kernel.org/r/20260825-for-upstream-dt-tmp401-vcc-tsc-v2-1-cbc360ec51d9@free.fr

Changes in v2:
- Drop vcc-supply: tmp401.c has no regulator code, every hwmon binding
  that declares vcc-supply today has a driver consuming it, so declaring it
  as description only does not belong to this patch (Sashiko)
- Adapt the commit message
- Link to v1: https://lore.kernel.org/r/20260824-for-upstream-dt-tmp401-vcc-tsc-v1-1-ecb5ef7898bd@free.fr

Stray blank line. It's one sentence "commit foo....".
