e43ee86efb ARM: shmobile: R-Mobile: Consolidate rmobile_pd_suspend_*()
Consolidate the identical rmobile_pd_suspend_*() routines that just
return -EBUSY to prevent a PM domain from being powered down into a
single rmobile_pd_suspend_busy().

8c6067355f arm: boot: dts: dra7: enable dwc3 suspend PHY quirk
Whenever Suspend PHY bit is set on DRA7x devices,
USB will not work due to Set EP Configuration command
always failing.

This was only found after a recent commit 2164a47 (usb:
dwc3: set SUSPHY bit for all cores, which will be merged
for v3.19) added a missing *required* step to dwc3
initialization. Synopsys Databook requires that we enable
Suspend PHY bit after initialization but that, unfortunately,
breaks DRA7x.

Note that the same regression was already patched for AM437x.

4dd32e6d24 ARM: at91: dts: sama5d3: add ov2640 camera sensor support
According to v4l2 dt document, we add:
  a camera host: ISI port.
  a i2c camera sensor: ov2640 port.
to sama5d3xmb.dtsi.

The ov2640 node defines the pinctrls, clocks and refer to isi port.
The ISI node also has a reference to the ov2640 port.

fbe18601a5 ARM: at91: dts: sama5d3: change name of pinctrl of ISI_MCK
For sama5d3xmb board, the pins: pinctrl_isi_pck_as_mck is pck1, and
used to provide MCK for camera sensor.

We change its name to: pinctrl_pck1_as_isi_mck.

As we want camera sensor instead of ISI to configure the pck1 (ISI_MCK) pin.
So we remove this pinctrl from ISI DT node. It will be added in sensor's
DT node.

97889b14ed ARM: at91: dts: sama5d3: change name of pinctrl_isi_{power,reset}
For sama5d3xmb board, the pins: pinctrl_isi_{power,reset} is used to
power-down or reset camera sensor.
So we should let camera sensor instead of ISI to configure the pins.

This patch will change pinctrl name from pinctrl_isi_{power,reset} to
pinctrl_sensor_{power,reset}. And remove these two pinctrl from ISI's
DT node. We will add these two pinctrl to sensor's DT node.

29828c8756 ARM: shmobile: sh73a0 dtsi: Add memory-controller nodes
Add device nodes for the two SDRAM Bus State Controllers.
The SBSCs are located in the A4BC0 resp. A4BC1 PM domains, which must
not be powered down, else the system will crash.

References to the A4BC0 and A4BC1 PM domains will be added later.

f4c6d004ea ARM: shmobile: r8a7740 dtsi: Add memory-controller node
Add a device node for the DDR3 Bus State Controller (DBSC3).
The DBSC3 is located in the A4S PM domain, which must not be powered
down, else the system will crash.

This has no visible effect for now, as A4S was never turned off anyway
because its child PM domain A3SM contains the CPU core.

2173fc7cb6 ARM: shmobile: R-Mobile: Add DT support for PM domains
Populate the PM domains from DT, and provide support to hook up devices
to their respective PM domain.

The always-on power area (e.g. C5 on r8a7740) is created as a PM domain
without software control, to allow Run-Time management of module clocks
for hardware blocks inside this area.

Special cases like PM domains containing CPUs, the console device, or
Coresight-ETM, are handled by scanning the DT topology.

As long as the ARM debug/perf code doesn't use resource management with
runtime PM support, the power area containing Coresight-ETM (e.g. D4 on
r8a7740) must be kept powered to avoid a crash during resume from s2ram
(dbg_cpu_pm_notify() calls reset_ctrl_regs() unconditionally, causing an
undefined instruction oops).

Initialization is done from core_initcall(), as the
"renesas,intc-irqpin" driver uses postcore_initcall().

643165c8bb Merge tag 'uaccess_for_upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost into asm-generic
Merge "uaccess: fix sparse warning on get/put_user for bitwise types" from Michael S. Tsirkin:

At the moment, if p and x are both tagged as bitwise types,
some of get_user(x, p), put_user(x, p), __get_user(x, p), __put_user(x, p)
might produce a sparse warning on many architectures.
This is a false positive: *p on these architectures is loaded into long
(typically using asm), then cast back to typeof(*p).

When typeof(*p) is a bitwise type (which is uncommon), such a cast needs
__force, otherwise sparse produces a warning.

Some architectures already have the __force tag, add it
where it's missing.

I verified that adding these __force casts does not supress any useful warnings.

Specifically, vhost wants to read/write bitwise types in userspace memory
using get_user/put_user.
At the moment this triggers sparse errors, since the value is passed through an
integer.

For example:
    __le32 __user *p;
    __u32 x;

both
    put_user(x, p);
and
    get_user(x, p);
should be safe, but produce warnings on some architectures.

While there, I noticed that a bunch of architectures violated
coding style rules within uaccess macros.
Included patches to fix them up.
