Re: [PATCH v10 28/36] pinctrl: airoha: an7583: add support for npu_uart pinmux

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The patch adds a new `npu_uart` pin group to the `uart` function in the pinctrl driver but fails to update the corresponding devicetree bindings (`airoha,an7583-pinctrl.yaml`), which will cause `dtbs_check` validation to fail for device trees using this pin group.

[Severity: Low]
Does this change also require an update to the device tree bindings?

The npu_uart group is added to the uart function here, but it appears to be
missing from the allowed enum items in
Documentation/devicetree/bindings/pinctrl/airoha,an7583-pinctrl.yaml:

          - if:
              properties:
                function:
                  const: uart
            then:
              properties:
                groups:
                  items:
                    enum: [uart2, uart2_cts_rts, hsuart, hsuart_cts_rts,
                           uart4, uart5]

Without adding npu_uart to this list, will dtbs_check validation fail for
device trees that attempt to use the newly added group?
