Ups, I completely forgot about Josh's patch, thanks for the reminder. 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.
