I guess there's nothing to explicitly state if it's a sink or a source in the port nodes? The table made it nice and clear which were sink/source ... and that gets a bit obfuscated here. Of course it's mentioned as they are "Input" or "Output" nodes, but I liked the clarity the table had. Not a blocker though I don't think.... > + > + properties: > + endpoint: > + $ref: /schemas/media/video-interfaces.yaml# > + unevaluatedProperties: false > + > + properties: > + clock-lanes: > + maxItems: 1 > + > + data-lanes: > + minItems: 1 > + maxItems: 4 > + > + required: > + - clock-lanes > + - data-lanes > + > + port@b: > + $ref: /schemas/graph.yaml#/$defs/port-base > + unevaluatedProperties: false > + description: > + Output port node, single endpoint describing the CSI-2 transmitter TXB.

The 'main' has to be 70, and probably kept first, which is probably why I split it into two lines at least.... Is there a specific reason it's been joined up to a single line here? Anyway, I don't see any blockers here - just discussion points really, and I'm pleased to see it converted.

I explicitly chose to use input / output port here instead of source / sink as the later is V4L2 specific while input / output is used in the hardware manual. I have no strong opinion here so can change if we can find a larger consensus for what word to use for media bindings. > > > > + > > + properties: > > + endpoint: > > + $ref: /schemas/media/video-interfaces.yaml# > > + unevaluatedProperties: false > > + > > + properties: > > + clock-lanes: > > + maxItems: 1 > > + > > + data-lanes: > > + minItems: 1 > > + maxItems: 4 > > + > > + required: > > + - clock-lanes > > + - data-lanes > > + > > + port@b: > > + $ref: /schemas/graph.yaml#/$defs/port-base > > + unevaluatedProperties: false > > + description: > > + Output port node, single endpoint describing the CSI-2 transmitter TXB. > > I do like that we managed to align TXA = port 10 = a and TXB = port 11 = > b... I find it annoying that we went over 10 nodes, as port@a { reg = <10>; } is really not straight forward ;-) > > > > > + > > + properties: > > + endpoint: > > + $ref: /schemas/media/video-interfaces.yaml# > > + unevaluatedProperties: false > > + > > + properties: > > + clock-lanes: > > + maxItems: 1 > > + > > + data-lanes: > > + maxItems: 1 > > + > > + required: > > + - clock-lanes > > + - data-lanes > > + > > +allOf: > > + - if: > > + properties: > > + compatible: > > + contains: > > + const: adi,adv7481 > > + then: > > + properties: > > + interrupts: > > + minItems: 1 > > + maxItems: 3 > > + > > + interrupt-names: > > + minItems: 1 > > + items: > > + - enum: [ intrq1, intrq2, intrq3 ] > > + - enum: [ intrq1, intrq2, intrq3 ] > > + - enum: [ intrq1, intrq2, intrq3 ] > > + else: > > + properties: > > + interrupts: > > + minItems: 1 > > + maxItems: 2 > > + > > + interrupt-names: > > + minItems: 1 > > + items: > > + - enum: [ intrq1, intrq2 ] > > + - enum: [ intrq1, intrq2 ] > > + > > +additionalProperties: false > > Ah yes, this is actually an improvement on the earlier version as now > it's clear that there is a difference between the number of IRQs which > wasn't evident before. > > > + > > +required: > > + - compatible > > + - reg > > + - ports > > + > > +examples: > > + - | > > + #include <dt-bindings/interrupt-controller/irq.h> > > + > > + i2c { > > + #address-cells = <1>; > > + #size-cells = <0>; > > + > > + video-receiver@70 { > > + compatible = "adi,adv7482"; > > + reg = <0x70 0x71 0x72 0x73 0x74 0x75 0x60 0x61 0x62 0x63 0x64 0x65>; > > I know this was like that before, but it seems odd having 0x70-75, then > 0x60-65. > > The 'main' has to be 70, and probably kept first, which is probably why > I split it into two lines at least.... > > Is there a specific reason it's been joined up to a single line here? Not really it fitted on one line within 80 characters so I probably did it with out thinking when fixing the formating. But I agree it makes more sens to align it will reg-names splitting.
