Here indeed, this is a string, not a list, so items are wrong. Best regards, Krzysztof
Hi Krzysztof On Sun, Aug 27, 2023 at 09:56:06AM +0200, Krzysztof Kozlowski wrote: > On 26/08/2023 23:04, Serge Semin wrote: > >> + clock-names: > >> + items: > >> + - const: stmmaceth > > > > clock-names: > > const: stmmaceth > > ? > > The existing syntax is correct. This is a string array. Could you please clarify whether it's a requirement (always specify items: property for an array) or just an acceptable option (another one is suggested in my comment)? I am asking because: 1. In this case the "clock-names" array is supposed to have only one item. Directly setting "const: stmmaceth" with no items: property shall simplify it. 2. There are single-entry "clock-names" property in the DT-bindings defined as I suggested. 3. There is a "compatible" property which is also a string array but it can be defined as I suggested (omitting the items property). so based on all of that using the "items:"-based constraint here seems redundant. Am I wrong to think like that? If so in what aspect? -Serge(y) > > > > >> + > >> + interrupts: > >> + maxItems: 1 > >> + > > > >> + interrupt-names: > >> + items: > >> + - const: macirq > > > > interrupt-names: > > const: macirq > > ? > > As well. > > > > >> + > >> + loongson,ls1-syscon: > >> + $ref: /schemas/types.yaml#/definitions/phandle > >> + description: > >> + Phandle to the syscon containing some extra configurations > >> + including PHY interface mode. > >> + > > > >> + phy-mode: > >> + items: > >> + - enum: > >> + - mii > >> + - rmii > > > > phy-mode: > > enum: ... > > ? > > Here indeed, this is a string, not a list, so items are wrong. > > > > Best regards, > Krzysztof >

Am I wrong to think like that? If so in what aspect? Syntax is correct in both cases. However the single list compatible *cannot grow*, while single list clock might, when developer notices that the binding was incomplete. People add binding matching drivers, not the hardware, thus having incomplete list of clocks is happening all the time. Best regards, Krzysztof
