As Russell pointed out, we should never #define a macro starting
with CONFIG_ in a source file, as that is rather confusing.
This renames the macro to avoid the symbol clash.

For USB gadget on port A (device mode):
- pin PA31 is configured as an input GPIO which triggers an interrupt when
vbus is detected on USB port A.
- pin PB9 is configured as an output GPIO and set to low level so the
board doesn't supply vbus to USB port A.
For USB host:
- pin PB10 is configured as an output GPIO and is active at high level.
The ohci driver will activate this pin so the board supplies vbus to USB
port B.
- pin PB9 should be configured as an output GPIO and active at high level
to use to USB port A in host mode (conflicts with USB gadget).

In the final versions of the Porter board (called "PORTER_C") Renesas
decided to get rid of the Maxim Integrated MAX3355 OTG chip and didn't
add any other provision to differ the host/gadget mode, so we'll have to
remove no longer valid "renesas,enable-gpio" property from the HS-USB
device node. Hopefully, the earlier revisions of the board were never
seen in the wild...

Let the non boot cpus call into idle with the corresponding hotplug state, so
the hotplug core can handle the further bringup. That's a first step to
convert the boot side of the hotplugged cpus to do all the synchronization
with the other side through the state machine. For now it'll only start the
hotplug thread and kick the full bringup of the cpu.

All pinctrl nodes for the Atmel pinctrl controller need to have their
bias configuration explicitly defined. Otherwise, the pinctrl mapping
is not valid.
It works for now as the pinctrl driver proceeds even with invalid
mappings, but this can become an issue, if the pinctrl driver starts
to require valid mappings. Additionally, the pin is not protected from
being remapped later by an other driver.
There is an external 1kOhms pull-up to 3.3V, so no bias is required on
the Ethernet PHY's interrupt line.

After adding cpufreq-dt support to Exynos542x, the Odroid XU3-Lite can
be easily overheated when launching eight CPU-intensive tasks:
thermal thermal_zone3: critical temperature reached(121 C),shutting down
This seems to be specific to Odroid XU3-Lite board which officially
supports lower frequencies than regular XU3 or XU4. When working at
maximum CPU speed (1800 MHz big and 1300 MHz LITTLE) in warmer place for
longer time, the fan fails to cool down the board and it reaches
critical temperature.
Add CPU cooling to Exynos5422/5800 to fix this issue. When reaching last
interrupt-driven trip-point (70 degrees of Celsius) start passive
cooling in polling mode (slowing CPU by 2 steps). When reaching 85
degrees of Celsius, start slowing even more, down to 600 MHz.

Programming the active state in the (re)distributor can be an
expensive operation so it makes some sense to try and reduce
the number of accesses as much as possible. So far, we
program the active state on each VM entry, but there is some
opportunity to do less.
An obvious solution is to cache the active state in memory,
and only program it in the HW when conditions change. But
because the HW can also change things under our feet (the active
state can transition from 1 to 0 when the guest does an EOI),
some precautions have to be taken, which amount to only caching
an "inactive" state, and always programing it otherwise.
With this in place, we observe a reduction of around 700 cycles
on a 2GHz GICv2 platform for a NULL hypercall.

So far, our handling of cache maintenance by VA has been pretty
simple: Either the access is in the guest RAM and generates a S2
fault, which results in the page being mapped RW, or we go down
the io_mem_abort() path, and nuke the guest.
The first one is fine, but the second one is extremely weird.
Treating the CM as an I/O is wrong, and nothing in the ARM ARM
indicates that we should generate a fault for something that
cannot end-up in the cache anyway (even if the guest maps it,
it will keep on faulting at stage-2 for emulation).
So let's just skip this instruction, and let the guest get away
with it.

This patch provides unique model identifiers for revision B1 of

All the generic L2 cache handling code is encapsulated by a
check if the L2 cache is enabled. If it's enabled already, the code
is skipped. The write to the L2-Cache controller from non-secure
world causes an imprecise external abort. This is needed in
scenarios where one of the cores runs an other OS, e.g. an RTOS.

the cpu_suspend() helper, we otherwise get a harmless

This moves the option to the SOC_IMX6 option that actually

Since the switch from mmp_pdma to pxa_dma driver for pxa architectures,
the pxa_dma requires 2 arguments, namely the requestor line and the
requested priority.
Fix the only left device node which was still passing only one argument,
making the pxa3xx-nand driver misbehave in a device-tree configuration,
ie. failing all data transfers.
Fixes: c943646d1f ("ARM: dts: pxa: add dma engine node to pxa3xx-nand")

The core clock does not depend on corediv, so enabling corediv
based on the clock is not really correct. Move the corediv
config option from the clock driver Kconfig to the mvebu Kconfig
so that it can be enabled by the MACH option instead.
This also enables corediv on Armada 375 and 38X, which was
previously missing.

APB0 is bearly mentioned in H3 User Manual and it is only setup in the

gate for R_PIO exists and works, though. There are probably other gates
there but I don't know their order right now and I don't have access to
their peripherals on my board to test them.
After some experiments and reviewing how this is organized on other
sunxi SoCs, I couldn't actually find any way to disable clocks for R_PIO
and they are working properly without doing anything so I assume they
are connected straight to the 24Mhz oscillator for now.

K2G is the newest addition of TI's Keystone 2 product family. It is a
single core Cortex A15 and a C66x DSP.
K2G supports standard peripherals such as SPI, UART, MMC and USB 2.0.
Includes two dual-core Programmable Real-time Unit and Industrial
Communication Subsystems (PRU-ICSS).
The technical reference manual for K2G can be found here:
http://www.ti.com/lit/ug/spruhy8/spruhy8.pdf
This device is targeted for a variety of applications which include, but
are not limited to:
Home audio
Professional audio
Industrial Programmable Logic Control
The peripheral nodes that have been included in this patch have been
tested during bring-up. Since all peripherals will not necessarily be
used on all boards, disable all peripherals by default. This allow
the board dts to selectively choose which peripherals it wants to
enable.
This SoC now uses the next generation of power management architecture
with the PM functionality located in a microcontroller embedded in the SOC.
Support for this new PM architecture along with other peripherals will be
added in future patches.

and now is

The problem:
On -rt, an emulated LAPIC timer instances has the following path:
1) hard interrupt
2) ksoftirqd is scheduled
3) ksoftirqd wakes up vcpu thread
4) vcpu thread is scheduled
This extra context switch introduces unnecessary latency in the
LAPIC path for a KVM guest.
The solution:
Allow waking up vcpu thread from hardirq context,
thus avoiding the need for ksoftirqd to be scheduled.
Normal waitqueues make use of spinlocks, which on -RT
are sleepable locks. Therefore, waking up a waitqueue
waiter involves locking a sleeping lock, which
is not allowed from hard interrupt context.

This patch reduces the average latency in my tests from 14us to 11us.

This patch adds USB HS support in host mode only.
This port supports OTG mode, but the device more is not working
properly as of now.
Once the device mode fixed, the node will be updated to support OTG.

KVM/ARM fixes for 4.5-rc6
- Fix per-vcpu vgic bitmap allocation
- Do not give copy random memory on MMIO read
- Fix GICv3 APR register restore order
Add a custom reset handler for DRA7x PCIeSS. This
handler is required to deassert PCIe hardreset lines
after they have been asserted.
This enables the PCIe driver to access registers after
PCIeSS has been runtime enabled without having to
deassert hardreset lines itself.
With this patch applied, used lspci to make sure
connected PCIe device enumerates on DRA74x and DRA72x
EVMs.

This patch cleans up various map.h under mach-exynos, mach-s3c24xx and
plat-samsung by removing unused register offset. This patch also does a
minor nitpick of changing EXYNOS4 to EXYNOS from comment section of
header file "mach-exynos/include/mach/map.h".

This includes trivial cleanup in exynos files such as
- remove unused header files inclusion from exynos.c, s5p-dev-mfc.c,
firmware.c, pm.c.
- move inclusion of of.h from common.h to pm.c where it is really
required
