'minItems' alone does not impose upper bound, unlike 'maxItems' which implies lower bound. Add missing clock constraint so the list will have exact number of items (clocks).

dt-bindings: serial: 8250: Make clocks and clock-frequency exclusive 2025-07-06T08:58:01+00:00 Yao Zi ziyao@disroot.org 2025-06-23T09:34:45+00:00 f8530462a349b8d22772a83db2a338867ee3b86c commit 09812134071b3941fb81def30b61ed36d3a5dfb5 upstream. The 8250 binding before converting to json-schema states, - clock-frequency : the input clock frequency for the UART or - clocks phandle to refer to the clk used as per Documentation/devicetree for clock-related properties, where "or" indicates these properties shouldn't exist at the same time. Additionally, the behavior of Linux's driver is strange when both clocks and clock-frequency are specified: it ignores clocks and obtains the frequency from clock-frequency, left the specified clocks unclaimed. It may even be disabled, which is undesired most of the time. But "anyOf" doesn't prevent these two properties from coexisting, as it considers the object valid as long as there's at LEAST one match. Let's switch to "oneOf" and disallows the other property if one exists, precisely matching the original binding and avoiding future confusion on the driver's behavior.

commit 09812134071b3941fb81def30b61ed36d3a5dfb5 upstream.

The 8250 binding before converting to json-schema states,

  - clock-frequency : the input clock frequency for the UART
  	or
  - clocks phandle to refer to the clk used as per Documentation/devicetree

for clock-related properties, where "or" indicates these properties
shouldn't exist at the same time.

Additionally, the behavior of Linux's driver is strange when both clocks
and clock-frequency are specified: it ignores clocks and obtains the
frequency from clock-frequency, left the specified clocks unclaimed. It
may even be disabled, which is undesired most of the time.

But "anyOf" doesn't prevent these two properties from coexisting, as it
considers the object valid as long as there's at LEAST one match.

Let's switch to "oneOf" and disallows the other property if one exists,
