Update the CMT clockevent rating from 125 to 80.
This resolves a boot-failure regression for kzm9g-reference in v3.10-rc1
introduced by f7db706b13 ("ARM: 7674/1: smp:
Avoid dummy clockevent being preferred over real").
The patch noted above reduces the rating of dummy clockevent from 400 to 100.
This patch reduces the rating of CMT so that it is once again less than that
of the dummy clockevent.

These are cleanups and smaller changes that either depend on earlier
feature branches or came in late during the development cycle.
We normally try to get all cleanups early, so these are the exceptions:
- A follow-up on the clocksource reworks, hopefully the last time
we need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc cleanup
series because of interdependencies with timer drivers now moved out
of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes
for Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10.

These patches are all for Renesas shmobile, and depend on the earlier
pinctrl updates. Remarkably, this adds support for three new SoCs:
r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is
for pinctrl (using the new subsystem) and for clocks (not yet using the
common clock subsystem). The latter will have to get converted in one
of the upcoming releases, but shmobile is not ready for that yet.
The series also contains Renesas shmobile board changes, adding one
board file for each of the three new SoCs. These boards are using a
mix of classic and device-tree based probing, as there is still a lot of
infrastructure in shmobile that has not been converted to DT yet. Once
those are resolved to the degree that no board specific setup code is
needed, they can get folded into the respective SoC setup files.

This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem
specific interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into
platform specific interface, or to get called from platform specific
code, as long as all information about the hardware is provided
through a device tree.
Most of the drivers we touch this time are for clocksource. Since
now most of them are part of drivers/clocksource, I expect that we
won't have to touch these again from arm-soc and can let the
clocksource maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the
merge conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface
for taking devices on the SoC out of reset or back into reset.

window, and we are going to have other platforms (at least tegra

Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver changes from Olof Johansson:
"This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem specific
interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into platform
specific interface, or to get called from platform specific code, as
long as all information about the hardware is provided through a
device tree.
Most of the drivers we touch this time are for clocksource. Since now
most of them are part of drivers/clocksource, I expect that we won't
have to touch these again from arm-soc and can let the clocksource
maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the merge
conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface for
taking devices on the SoC out of reset or back into reset. Patches to
use this interface on i.MX follow later in this merge window, and we
are going to have other platforms (at least tegra and sirf) get
converted in 3.11. This will let us get rid of platform specific
callbacks in a number of platform independent device drivers."

This has a nasty set of conflicts with the exynos MCT code, which was
moved in a separate branch, and then fixed up when merged in, but still
conflicts a bit here. It should have been sorted out by this merge though.
We no longer need to set up the reset pin for the st1232 in the board
code, but can pass the GPIO number via the platform data to the driver.
This results in a cleaner grouping of the device setup.

This converts arm and arm64 to use CLKSRC_OF DT based initialization for
the arch timer. A new function arch_timer_arch_init is added to allow for
arch specific setup.
This has a side effect of enabling sched_clock on omap5 and exynos5. There
should not be any reason not to use the arch timers for sched_clock.

Add the GPIO I/O memory range to the r8a7790 PFC device.
This extra I/O memory range is needed when using the PFC
tables to drive both pin functions (using PINCTRL or
function GPIO for old code) and actual GPIO. The goal is
however to use a separate GPIO driver in the long run
and when that happens this extra I/O memory range can
be removed.

Here is the big Gadget & PHY pull request. Many of us have
been really busy lately getting multiple drivers to a better
position.
Since this pull request is so large, I will divide it in sections
so it's easier to grasp what's included.
- cleanups:
. UDC drivers no longer touch gadget->dev, that's now udc-core
responsibility
. Many more UDC drivers converted to usb_gadget_map/unmap_request()
. UDC drivers no longer initialize DMA-related fields from gadget's
device structure
. UDC drivers don't touch gadget.dev.driver directly
. UDC drivers don't assign gadget.dev.release directly
. Removal of some unused DMA_ADDR_INVALID
. Introduction of CONFIG_USB_PHY
. All phy drivers have been moved to drivers/usb/phy and renamed to
a common naming scheme
. Fix PHY layer so it never returns a NULL pointer, also fix all
callers to avoid using IS_ERR_OR_NULL()
. Sparse fixes all over the place
. drivers/usb/otg/ has been deleted
. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
usage
- new features:
. UDC core now provides a generic way for tracking and reporting
UDC's state (not attached, resuming, suspended, addressed,
default, etc)
. twl4030-usb learned that it shouldn't be enabled during init
. Full DT support for DWC3 has been implemented
. ab8500-usb learned about pinctrl framework
. nop PHY learned about DeviceTree and regulators
. DWC3 learned about suspend/resume
. DWC3 can now be compiled in host-only and gadget-only (as well as
DRD) configurations
. UVC now enables streaming endpoint based on negotiated speed
. isp1301 now implements the PHY API properly
. configfs-based interface for gadget drivers which will lead to
the removal of all code which just combines functions together
to build functional gadget drivers.
. f_serial and f_obex were converted to new configfs interface while
maintaining old interface around.
- non-critical fixes:
. UVC gadget driver got fixes for Endpoint usage and stream calculation
. ab8500-usb fixed unbalanced clock and regulator API usage
. twl4030-usb got a fix for when OMAP3 is booted with cable connected
. fusb300_udc got a fix for DMA usage
. UVC got fixes for two assertions of the USB Video Class Compliance
specification revision 1.1
. build warning issues caused by recent addition of __must_check to
regulator API
These are all changes which deserve a mention, all other changes are related
to these one or minor spelling fixes and other similar tasks.

usb: patches for v3.10 merge window
Here is the big Gadget & PHY pull request. Many of us have
been really busy lately getting multiple drivers to a better
position.
Since this pull request is so large, I will divide it in sections
so it's easier to grasp what's included.
- cleanups:
. UDC drivers no longer touch gadget->dev, that's now udc-core
responsibility
. Many more UDC drivers converted to usb_gadget_map/unmap_request()
. UDC drivers no longer initialize DMA-related fields from gadget's
device structure
. UDC drivers don't touch gadget.dev.driver directly
. UDC drivers don't assign gadget.dev.release directly
. Removal of some unused DMA_ADDR_INVALID
. Introduction of CONFIG_USB_PHY
. All phy drivers have been moved to drivers/usb/phy and renamed to
a common naming scheme
. Fix PHY layer so it never returns a NULL pointer, also fix all
callers to avoid using IS_ERR_OR_NULL()
. Sparse fixes all over the place
. drivers/usb/otg/ has been deleted
. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
usage
- new features:
. UDC core now provides a generic way for tracking and reporting
UDC's state (not attached, resuming, suspended, addressed,
default, etc)
. twl4030-usb learned that it shouldn't be enabled during init
. Full DT support for DWC3 has been implemented
. ab8500-usb learned about pinctrl framework
. nop PHY learned about DeviceTree and regulators
. DWC3 learned about suspend/resume
. DWC3 can now be compiled in host-only and gadget-only (as well as
DRD) configurations
. UVC now enables streaming endpoint based on negotiated speed
. isp1301 now implements the PHY API properly
. configfs-based interface for gadget drivers which will lead to
the removal of all code which just combines functions together
to build functional gadget drivers.
. f_serial and f_obex were converted to new configfs interface while
maintaining old interface around.
- non-critical fixes:
. UVC gadget driver got fixes for Endpoint usage and stream calculation
. ab8500-usb fixed unbalanced clock and regulator API usage
. twl4030-usb got a fix for when OMAP3 is booted with cable connected
. fusb300_udc got a fix for DMA usage
. UVC got fixes for two assertions of the USB Video Class Compliance
specification revision 1.1
. build warning issues caused by recent addition of __must_check to
regulator API
These are all changes which deserve a mention, all other changes are related
to these one or minor spelling fixes and other similar tasks.

This patch adds SMSC ethernet support on Bock-W
Bock-W SMSC needs FPGA settings which enables interrupt.
This patch does it on bockw_init() function.
As notes for future, this FPGA settings should be updated,
since this FPGA is using cascaded interrupt.
Current code is assuming that this FPGA interrupt user is only SMSC.

This patch adds r8a7778_init_irq_extpin() for IRQ0 - IRQ3.
But this patch doesn't enable DT settings on r8a7778.dts,
because R8A7778 chip external IRQ depends on
IRQ0 - IRQ3 pin encoding which came from platform board

MMCIF and SDHI1 share the same slot on mackerel. One of them is selected
by a jumper, which cannot be queried from software. Currently in software
one of the two interfaces is selected, depending whether or not the MMCIF
driver is enabled. This is not optimal, since the kernel has to be rebuilt
to switch from one interface to another. Still, so far there isn't a
better option. At least make this selection consistent.

R-Car H1 has many clocks, and it is possible to read/use clock ratio
of these clocks from FRQMRx as DIV4 clocks.
But, these ratio are fixed value and these are decided
by MD pin status.
This means that we can use fixed ratio clock via MD pin status,

- Kconfig: select ARM_GIC and RENESAS_INTC_IRQPIN
- intc-r8a7740: Throw out all legacy INTC code and init the GIC. We need
to mask out all shared IRQs as it is needed by the
shared intc_irqpin driver.
- setup-r8a7740: Add 4 irqpin devices to handle external IRQs and update
all IRQ numbers to point to the GIC SPI.

Provide alternate board code for the kzm9g to demonstrate
how DT may be used given the current state of driver
device tree support. This is intended to act as a reference
for mach-shmobile developers.
Some notes:
* Brings up the GIC interrupt handler using device tree
* Brings up the following device using device tree:
- MMCIF (MMC)
* Does not bring up the INTC interrupt controller at all,
thus external devices may not be used. In particular,
the SMSC ethernet device may not be used and thus
NFS root may not be used.
* Uses existing C code and not device tree to initialise the following,
which are needed for a working board:
- SCIF (Serial)
- CMT (Clock)
- PFC (GPIO)
To use this alternate board code instead of the normal board code,
CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config.
And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used.

Update the r8a7779 IRQ code to make use of the
INTC External IRQ pin driver for external
interrupt pins IRQ0 -> IRQ3.
The r8a7779 SoC can like older SH SoCs configure
to use the IRQ0 -> IRQ3 signals as individual
interrupts or a combined IRL mode.
Without this patch the r8a7779 SoC code does
not fully support external IRQ pins in individual
IRQ mode. The r8a7779 PFC code does not yet have
gpio_to_irq() support so no need to update such
code.
At this point the DT reference implementations
are not covered. In the future such code shall
tie in the INTC External IRQ pin driver via
DT, so this kind of verbose code is not needed
for the long term DT case.
