There should be at least two reserved memory nodes defined. The Does this enforce the maxItems to be 2 only now? Or should this be dropping the minItems here which matches the length of items instead of maxItems? I have originally listed the individual item list only for the mandatory items and rest are scalable. I provided this through "additionalItems: true" under this property. Also, have the exact same usage in Documentation/devicetree/bindings/remoteproc/ti,k3-r5f-rproc.yaml as well which is not included in this patch. > diff --git a/Documentation/devicetree/bindings/remoteproc/ti,omap-remoteproc.yaml b/Documentation/devicetree/bindings/remoteproc/ti,omap-remoteproc.yaml > index 73400bc6e91d..75161f191ac3 100644 > --- a/Documentation/devicetree/bindings/remoteproc/ti,omap-remoteproc.yaml > +++ b/Documentation/devicetree/bindings/remoteproc/ti,omap-remoteproc.yaml > @@ -116,7 +116,6 @@ properties: > list, in the specified order, each representing the corresponding > internal RAM memory region. > minItems: 1 > - maxItems: 3 > items: > - const: l2ram > - const: l1pram [snip] > diff --git a/Documentation/devicetree/bindings/soc/ti/ti,pruss.yaml b/Documentation/devicetree/bindings/soc/ti/ti,pruss.yaml > index dbc62821c60b..9790617af1bc 100644 > --- a/Documentation/devicetree/bindings/soc/ti/ti,pruss.yaml > +++ b/Documentation/devicetree/bindings/soc/ti/ti,pruss.yaml > @@ -100,7 +100,6 @@ patternProperties: > properties: > reg: > minItems: 2 # On AM437x one of two PRUSS units don't contain Shared RAM. > - maxItems: 3 > items: > - description: Address and size of the Data RAM0. > - description: Address and size of the Data RAM1. > @@ -111,7 +110,6 @@ patternProperties: > > reg-names: > minItems: 2 > - maxItems: 3 > items: > - const: dram0 > - const: dram1 regards Suman
