This flag is a no-op now (see commit 47b0eeb3dc8a "clk: Deprecate
CLK_IS_ROOT", 2016-02-02) so remove it.

All configurations are lost and the registers will have
default values when the hardware is suspended and resumed,
so saving the private register space context on suspend, and
restoring it on resume.

Since device_add_property_set() now always takes a copy of
the property_set, and also since the fwnode type is always
hard coded to be FWNODE_PDATA, there is no need for the
drivers to deliver the entire struct property_set. The
function can just create the instance of it on its own and
bind the properties from the drivers to it on the spot.
This renames device_add_property_set() to
device_add_properties(). The function now takes struct
property_entry as its parameter instead of struct
property_set.

We forgot to remove the clock tree if something goes wrong in ->probe(). Add a
call to intel_lpss_unregister_clock() on error path in ->probe() to fix the
potential issue.

If the boot firmware does not support ACPI we need a way to pass device
configuration information to the drivers. The unified device properties API
already supports passing platform data via properties so let's take
advantage of that and allow probe drivers to pass set of properties to the
host controller driver.
In order to do that we need to be able to modify the MFD cell corresponding
the host controller, so make the core driver to take copy of the cell
instead of using it directly. Then we can assign info->pset to the
resulting copy of a cell and let the MFD core to assign that to the
resulting device.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic cleanups from Arnd Bergmann:
"The asm-generic changes for 4.4 are mostly a series from Christoph
Hellwig to clean up various abuses of headers in there. The patch to
rename the io-64-nonatomic-*.h headers caused some conflicts with new
users, so I added a workaround that we can remove in the next merge
window.
The only other patch is a warning fix from Marek Vasut"
* tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
asm-generic: temporarily add back asm-generic/io-64-nonatomic*.h
asm-generic: cmpxchg: avoid warnings from macro-ized cmpxchg() implementations
gpio-mxc: stop including <asm-generic/bug>
n_tracesink: stop including <asm-generic/bug>

There are already helper functions to do 64-bit I/O on 32-bit machines, thus we
don't need to reinvent the wheel. In our case we can't use readq() / writeq()
even on 64-bit kernel since there is a hardware limitation (OCP bus is a 32-bit
bus).

The new coming Intel platforms such as Skylake will contain Sunrisepoint PCH.
The main difference to the previous platforms is that the LPSS devices are
compound devices where usually main (SPI, HSUART, or I2C) and DMA IPs are
present.
This patch brings the driver for such devices found on Sunrisepoint PCH.
