The patch titled
Subject: mfd: devicetree: bindings: add pm8xxx RTC description
has been removed from the -mm tree. Its filename was
mfd-devicetree-bindings-add-pm8xxx-rtc-description.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Josh Cartwright <joshc@xxxxxxxxxxxxxx>
Subject: mfd: devicetree: bindings: add pm8xxx RTC description
The PM8xxx family of PMICs contain an RTC. This RTC is described as a
subnode of the PM8xxx. Document these bindings, and replace the pwrkey
node in the example with the RTC, which is now described in this document.
While we're here, add a short description to the device tree bindings
describing what the the PM8xxx devices are and how they are expected to be
used.
