[PATCH] dt-bindings: display: panel: constrain 'reg' in DSI panels (part two)

[PATCH] dt-bindings: display: panel: constrain 'reg' in DSI panels (part two)

[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).

Few bindings missed previous fixup: LG SW43408 and Raydium RM69380.

Applied, thanks!
