There are a few of_* functions in include/linux/of_platform.h that are only defined when CONFIG_OF=y: of_platform_device_create() of_platform_device_destroy() of_platform_bus_probe() of_device_alloc() Rob, Frank, do you want me to create static inline dummy versions of these?

No, because generally you should not be using these functions directly. Yes, there are some users, but if you look at the tree, there are few or isolated (PowerPC) users. Using of_platform_populate/of_platform_depopulate is preferred.

Using > of_platform_populate/of_platform_depopulate is preferred. of_platform_device_destroy() is also used by sound/soc/qcom/qdsp6/* which is why I suggested this patch: https://marc.info/?l=alsa-devel&m=152932497413567 that adds "depends on OF" for SND_SOC_QDSP6 in sound/soc/qcom/Kconfig. Or do you think that a better solution would be to modify sound/soc/qcom/qdsp6/* so that it instead uses of_platform_populate()/of_platform_depopulate()? (Or perhaps this isn't even an option, I'm not at all familiar with the QDSP6 code).

As you said we could also do it with simple platform device too. I think adding compatible seems to be better option here along with of_platform_populate()/of_platform_depopulate(), I will try this! thanks, srini > But if you want to add empty functions for just > of_platform_device_{create,destroy}, I guess that is fine. > > Rob > -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Since commit cab673583d96 ("soc: Unconditionally include qcom Makefile"), we unconditionally include the soc/qcom/Makefile. This opens up the possibility to compile test the code even when building for other architectures. This patch series prepares and enables all but two Kconfigs to be compile tested even when building for other architectures. Changes since v1: Added two new patches, "ASoC: qdsp6: Add depends on OF" and "soc: qcom: Remove bogus depends on OF". Patch "soc: qcom: Allow COMPILE_TEST of all drivers" now adds "depends on ARCH_QCOM || COMPILE_TEST" to the menu entry.
