changes (in addition to MFD, driver core and DMA changes) for v4.3
from Lee Jones.
* tag 'ib-mfd-base-acpi-dma-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd:
mfd: Add support for Intel Sunrisepoint LPSS devices
dmaengine: add a driver for Intel integrated DMA 64-bit
mfd: make mfd_remove_devices() iterate in reverse order
driver core: implement device_for_each_child_reverse()
klist: implement klist_prev()
Driver core: wakeup the parent device before trying probe
ACPI / PM: Attach ACPI power domain only once
PM / QoS: Make it possible to expose device latency tolerance to userspace
