[PATCH 0/3] dt-bindings: display: panel: constrain 'reg'

[PATCH 0/3] dt-bindings: display: panel: constrain 'reg'

[Krzysztof Kozlowski]

Hi,

Cleanups for display panel bindings.

Rob, maybe you could take entire set if it applies? I based it on
linux-next, so letl me know if I need to rebase on your for-next.

I actually do not know if devices affected here take more than one chip
select or DSI virtual channel number. I assume DTS and examples are
correct here. Worst case this can be fixed later - maxItems:2.

Best regards,
Krzysztof

[PATCH 1/3] dt-bindings: display: samsung,ams495qa01: add missing SPI properties ref

[Krzysztof Kozlowski]

Samsung AMS495QA01 panel is a SPI device, so it should reference
spi-peripheral-props.yaml schema to allow and validate the SPI device
properties.

[PATCH 2/3] dt-bindings: display: panel: constrain 'reg' in SPI panels

[Krzysztof Kozlowski]

SPI-attached devices could have more than one chip-select, thus their
bindings are supposed to constrain the 'reg' property to match hardware.
Add missing 'reg' constrain for SPI-attached display panels.

[PATCH 3/3] dt-bindings: display: panel: constrain 'reg' in DSI panels

[Krzysztof Kozlowski]

DSI-attached devices could respond to more than one virtual channel
number, thus their bindings are supposed to constrain the 'reg' property
to match hardware.  Add missing 'reg' constrain for DSI-attached display
panels, based on DTS sources in Linux kernel (assume all devices take
only one channel number).

It's most likely fine, but was there an ack from drm-misc maintainers?

> Documentation/devicetree/bindings/display/panel/lg,sw43408.yaml

Because those were added to drm-misc during the last cycle. So ideally
the patch should have gone through drm-misc.

Exact there's a conflict on today's next, Rob can you drop them so I can apply them via drm-misc ?
