This patchset enables a exynos4 usbphy and hsotg DT node for exynos4. The usb
phy node uses generic exynos phy driver. The driver uses PMU syscon and SYSREG
syscon phandles.

But since syscon driver uses compatible "syscon" and once the syscon driver is probed, the exynos PMU platform driver [1] will NEVER be probed. So my question is, can we have 2 compatible strings for a DT node, and both the compatible strings are used for probing purpose? Recently I faced this issue on exynos5250, where i was testing PMU driver [1] and I noticed that PMU driver [1] was NEVER probed, if I enable syscon driver in menuconfig.

No, it is not possible to bind two drivers with different compatible strings to the same node. Basically this is because only one platform driver can be bound to particular platform device. The rule is that the most specific compatible string (e.g. the first from the left) that matches should be used, but I'm not sure if this is implemented this way in Linux kernel, especially considering that a platform driver usually probes when it is being registered. So we might have a race here, which you can work around by making sure that your PMU driver is always registered first (e.g. by lowering its initcall level).

I can see whichever driver registers platform driver first, it's probe is getting called. As in this particular case, PMU has two compatibility string as "samsung, exynosxxx-pmu", "syscon". But since "syscon" driver registers it's platform driver in postcore_initcall where as PMU platform driver [1], was registering as arch_initcall, only "syscon" probe got called. In my V2 patch for converting PMU as driver form, I dropped idea of converting into platform driver, because we can't remove "syscon" from binding as many other driver wants to access PMU register via regmap handle. By lowering it's initcall level may be I can make PMU probe gets called but then how other drivers will be able to access PMU regmap handles? > Best regards, > Tomasz > > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 11+ messages in thread
