Sorry, I don't think this is a good idea, unless you can force the IP team to release a version table containing version of _every_ IP for _every_ released SoC, including those historical ones, like S3C24xx and S3C64xx. Of course such tables should be available publicly. It's different issue and I agree with Mark Brown's comments. In addition, there might be other funny things going on with IPs and their surroundings, that could make a need to create several separate compatible values for the same IP revision, but on different SoCs, because it was integrated in a slightly different way. I believe we have choses the samsung,chip-ip scheme to avoid being dependent upon data that is not always publicly available, which is more future- (and past-) proof and also solves the integration problem. Well, I don't think so, because Samsung is no more just SoC vendor. Actually Samsung is providing just IP to customers, I think, they don't like to use the name, exynos for their SoC or Chip, because exynos, s3c or s5p whatever is Samsung's SoC brand name. If so, I think, my suggestion is more reasonable. See the example of Synopsys and ARM primecell...that's why I will try to do it. But I know I need to get agreement from DT guys and maybe I need more time than I expect ;-) Thanks, Kukjin -- To unsubscribe from this list: send the line unsubscribe linux-samsung-soc in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hmm, I just did a quick git grep over arch/arm/boot/dts and could not really find the samsung,ip-chip pattern. Except MFC (and without Padma's patch also I2S), which used samsung,ip- ip version, all the compatible values I can see are based on samsung,chip-ip pattern. I believe we discussed this issue several times already and finally agreed to use samsung,chip-ip for any new compatible values.
