charset="utf-8" clock-frequency is described as optional, with 100 kHz assumed when absent, yet it is also listed as required. The description is correct: i2c-riic calls i2c_parse_fw_timings() with use_defaults set, so the core falls back to I2C_MAX_STANDARD_MODE_FREQ when the property is absent. The stale requirement only produces dtbs_check noise on boards relying on the default: i2c@14400800 (renesas,riic-r9a09g047): 'clock-frequency' is a required property Drop it.
