It is in general expected, but there is no need for each binding to specify it. Other problem is that you did not actually test these bindings before sending... > + > + compatible: > + enum: > + - ti,cdce913 > + - ti,cdce925 > + - ti,cdce937 > + - ti,cdce949 > + > + reg: > + maxItems: 1 > + > + clocks: > + items: > + - description: fixed parent clock > + > + "#clock-cells": > + const: 1 > + > + vdd-supply: > + description: Regulator that provides 1.8V Vdd power supply > + > + vddout-supply: > + description: | > + Regulator that provides Vddout power supply. > + non-L variant: 2.5V or 3.3V for > + L variant: 1.8V for > + > + xtal-load-pf: > + $ref: /schemas/types.yaml#/definitions/uint32 > + description: | > + Crystal load-capacitor value to fine-tune performance on a > + board, or to compensate for external influences. > + > +patternProperties: > + "^PLL[1-4]$": > + type: object > + description: | > + optional child node can be used to specify spread > + spectrum clocking parameters for a board > + additionalProperties: false > + properties: > + spread-spectrum: > + $ref: /schemas/types.yaml#/definitions/uint32 > + description: SSC mode as defined in the data sheet > + > + spread-spectrum-center: > + type: boolean > + description: | > + Use "centered" mode instead of "max" mode.
