Some samsung platforms/drivers use "samsung,<chip>-<ip>", others "samsung,<ip>-<chip>". I don't personally care much one way or another, but it really should be consistent. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I remember there are no versions in datasheet for some IPs but something have like i2s and mfc. So "samsung,<ip>-<version>" is used for only i2s and mfc. But actually there are versions for Samsung IPs, no comments for that in datasheet. So I think, if Samsung can provide the specific version of Samsung IPs, we can use that like other platforms. I will prepare some table for that after meeting with Samsung hardware IP team so that samsung platform use one format "samsung,<ip>-<version>".

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. Best regards, Tomasz

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. 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.

datasheets are all NDAed anyway.

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 majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
