When multiple CPUs are related in one cpufreq policy, the first online
CPU will be chosen by default to handle cpufreq operations. Let's take
cpu0 and cpu1 as an example.
When cpu0 is offline, policy->cpu will be shifted to cpu1. cpu1's perf
capabilities should be initialized. Otherwise, perf capabilities are 0s
and speed change can not take effect.
This patch copies perf capabilities of the first online CPU to other
shared CPUs when policy shared type is CPUFREQ_SHARED_TYPE_ANY.

coreboot firmware
This patch adds generic device information to the DMI table of
the cros_ec_lpc driver, needed for Chromebooks/boxes using a
custom coreboot firmware.
The DMI info would not contain "Google_*" as BIOS version string,
instead the system vendor string would still be "GOOGLE", so this
seems to be a reasonable match for every Chromebook/box running
a custom firmware.

Instead of using platform device and deferrals to handle the case when i2C
adapters appear late in the game, and not handling device unbinding all

at that time.
In case when we have 2 Designware adapters in the system (Acer C720),
instead of counting and hoping they get enumerate din the right order,
let's switch to using their PCI devids (slot/function) that should be

During setup, qdio takes control of the presented ccw device and replaces
the device's IRQ handler with its own. To avoid any interference with
conccurent activity on the device, this should be done while holding the

During shutdown, qdio returns its ccw device back to control by the
upper-layer driver. But there is a remote chance that by the time where the
IRQ handler gets switched back, the interrupt for the preceding
ccw_device_{clear,halt} hasn't been presented yet.
Upper-layer drivers would then need to handle this IRQ - and since the IO
is issued with an intparm, it could very well be confused with whatever
intparm mechanism the driver uses itself (eg intparm == request address).
So when switching over the IRQ handler, also clear the intparm and have
upper-layer drivers deal with any such delayed interrupt as if it was
unsolicited.

The way we are supposed to put controller to sleep and wake it up does not
depend on the platform, but rather on controller itself, so we want to get
rid of suspend mode in platform data (and eventually get rid of platform
data completely). Unfortunately some early chromebooks (the original Pixel,
Acer C720) were shipped with config that requires manually re-enabling
touch reporting in T9. We will sort it out, but in the meantime let's
switch to a simple DMI quirk.
We'll keep pdata->suspend_mode for now and remove it when we rework
chromeos-laptop driver.

Pull ARM SA1100 updates from Russell King:
"We have support for arbitary MMIO registers providing platform GPIOs,
which allows us to abstract some of the SA11x0 CF support.
This set of updates makes that change"
* 'for-linus-sa1100' of git://git.armlinux.org.uk/~rmk/linux-arm:
ARM: sa1100/simpad: switch simpad CF to use gpiod APIs
ARM: sa1100/shannon: convert to generic CF sockets
ARM: sa1100/nanoengine: convert to generic CF sockets
ARM: sa1100/h3xxx: switch h3xxx PCMCIA to use gpiod APIs
ARM: sa1100/cerf: convert to generic CF sockets

Stephen reports that an x86 allmodconfig build fails to build the
of_pmem driver due to a missing definition of of_node_to_nid(). That
helper is currently only exported in the OF_NUMA=y case. In other cases,
ppc and sparc, it is a weak symbol, and outside of those platforms it is
a static inline.
Until an OF_NUMA=n configuration can reliably support usage of
of_node_to_nid() in modules across architectures, mark this driver as
'bool' instead of 'tristate'.
