Nevermind, the intention of the patch set was to get agreement on the approach of the qpnp-spmi driver. The rtc is just slightly reworked to platform driver downstream rtc driver. And last but not least I've used rtc to test the approach and as a example of PMIC function/peripheral driver. I will see what efforts are needed to reuse rtc-pm8xxx. > [1] > http://lists.infradead.org/pipermail/linux-arm-kernel/2013-October/207665.html > -- regards, Stan -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
