Hi, Thanks for the patches. I think "lge" it's the same prefix as "lg". There is no sense in having multiple vendor prefixes just because company splits inside business units or subsidiaries. The same as with other conglomerates, e.g. Samsung - if we wanted to be specific, there will be 4-5 Samsung vendors... Not mentioning that company organisation is not always disclosed and can change. We already have lg for several components, also made by LG Electronics. What about these? There is only one device with "lge", added back in 2016 without adding vendor prefix. I would propose to fix that one, instead of keeping duplicated "lg". Best regards, Krzysztof

Also worth noting that Google uses "LGE" in the Android device tree[1] or in the model name in the LG G Watch R kernel sources ("LGE APQ 8026v2 LENOK rev-1.0"). I don't have a strong opinion either way so I'm fine with either. If we decide to go with "lg" do we want to change the Nexus 5 devicetree (hammerhead) also, that one has the lge name in at least compatible and filename (I don't know how much of a breaking change that would be considered as). > We already have lg for several components, also made by LG Electronics. > What about these? > > There is only one device with "lge", added back in 2016 without adding > vendor prefix.

Have we sorted this lg- vs. lge- ?

This would make a mess and affect other DTS users. Most of existing usages of "lg" prefix are panels which are coming from another subsidiary of LG - LG Display. We all use there "lg" prefix, not "lgd". Plus mention before Bullhead mobile phone which is coming from LG Electronics. If we use generalized "lg" prefix for one subsidiary (LG Display), then let's do the same for another subsidiary - LG Electronics. Plus entire branding of LG Electronics products is LG: the website, the logo, advertisements. Everywhere except legal footer. I vote for using "lg" for both subsidiaries: LG Display and LG Electronics. Best regards, Krzysztof

This would make a mess and affect other DTS users. If wanted I can send a patch renaming the Nexus 5 to just LG, this would adjust both compatible in the file (which shouldn't really affect anything) and the filename (which probably will affect various scripts and whatnot used by existing users of the dtb). Is this something that can be done in mainline or should we rather just let it be? I'm not sure what the policies there are.

I'm not sure what the policies there are. The "lge" compatible is already in the bindings, so it should not be changed without valid reason. Imagine there is an user-space code parsing compatibles to adjust some power-management settings to different models. It would be broken now. What could be done is to mark it as deprecated and a add new one: compatible = "lg,hammerhead", "lge,hammerhead", "qcom,msm8974"; This should be safe for user-space and allow transition to common "lg".

I don't have an opinion on the filename. It does not matter to me. :) You can change it to "lg" or keep "lge". I don't see much benefits of changing it but I don't mind keeping it consistent.
