Here's the big char/misc driver pull request for 4.2-rc1.
Lots of mei, extcon, coresight, uio, mic, and other driver updates in
here. Full details in the shortlog. All of these have been in
linux-next for some time with no reported problems.

This patch adds new power supply charger driver support
for X-Power AXP288 PMIC integrated charger.
This driver interfaces with the axp20x mfd driver as a cell
and listens to extcon cable events for setting up charging.

This patch adds the extcon support for AXP288 PMIC which
has the BC1.2 charger detection capability. Additionally
it also adds the USB mux switching support b/w SOC and PMIC
based on GPIO control.

Add support for the AXP22x PMIC devices to the existing AXP20x driver.
This includes the AXP221 and AXP223, which are identical except for
the external data bus. Only AXP221 is added for now. AXP223 will be
added after it's Reduced Serial Bus (RSB) interface is supported.
AXP22x defines a new set of registers, power supplies and regulators,
but most of the API is similar to the AXP20x ones.
A new irq chip definition is used, even though the available interrupts
on AXP22x is a subset of those on AXP20x. This is done so the interrupt
numbers match those on the datasheet.
This patch only enables the interrupts, system power-off function, and PEK
sub-device. The regulator driver must first support different variants
before we enable it from the mfd driver.

X-Powers AXP288 is a customized PMIC for Intel Baytrail-CR platforms. Similar
to AXP202/209, AXP288 comes with USB charger, more LDO and BUCK channels, and
AD converters. It also provides extended status and interrupt reporting
capabilities than the devices currently supported in axp20x.c.
In addition to feature extension, this patch also adds ACPI binding for
enumeration.
This consolidated driver should support more X-Powers' PMICs in both device
tree and ACPI enumerated platforms.

This patch introduces the preliminary support for PMICs X-Powers AXP202
and AXP209. The AXP209 and AXP202 are the PMUs (Power Management Unit)
used by A10, A13 and A20 SoCs and developed by X-Powers, a sister company
of Allwinner.
The core enables support for two subsystems:
- PEK (Power Enable Key)
- Regulators
