Do we have some obstacles to not use a "common mailbox framework" for this IPC (shared memory) communication. It looks that it fits very well with our needs for this rpm-regulator and future submitting of smd driver? -- regards, Stan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Some > code already merged in arm-soc for creation of drivers/soc/qcom/ Hi Kumar, I do see rpm as somewhat equivalent to a pmic and that was why I followed suite and put it in mfd, but I can of course move it if you prefer. Lately I've been working on rpm, rpm-smd, smem, smd, smsm, smp2p patches for mainline. It could be argued that smd is a bus and should go in drivers/bus, but for the rest I fear that we just created drivers/soc/qcom as another dumping ground for things; a "Qualcomm specific drivers/mfd". But maybe that is the purpose of it ;) If I move the rpm driver, are there any conclusion to where I should move the dt binding documentation?

Rather than adding yet another mfd driver, how about we put this in drivers/soc/qcom as a much better location for the low level rpm code.
