We were expecting to sit on this branch through most of the merge window since
the contents was merged into our tree late, but we ended up sitting on all of
our contents so it can go in with the rest.
The contents here is:
- A large branch of cleanups of the CM/PRM blocks on OMAP.
- A couple of patches plumbing up CM/PRM on OMAP5 and DRA7.
- A branch with DT updates for Freescale i.MX. including some shuffling from
.dts to .dtsi (include) files that causes a little churn.

Now that the GPC has been converted to be a full blown irqchip
(and not a mole on the side of the GIC), booting a new kernel
with an old DT is likely to result in a rough ride for the user.
This patch makes sure such a situation is promptly detected and
the user made aware that a DT update is in order.

IMX6 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.
This patch does just this, updating the DT files to actually
reflect what the HW provides.
BIG FAT WARNING: because the DTs were so far lying by not
exposing the fact that the GPC block is actually the first
interrupt controller in the chain, kernels with this patch
applied wont have any suspend-resume facility when booted
with old DTs, and old kernels with updated DTs won't even boot.

Since commit 035a61c314 ("clk: Make clk API return per-user struct clk
instances"), clk API users can no longer check if two struct clk
pointers are pointing to the same hardware clock, i.e. struct clk_hw, by
simply comparing two pointers. That's because with the per-user clk
change, a brand new struct clk is created whenever clients try to look
up the clock by calling clk_get() or sister functions like clk_get_sys()
and of_clk_get(). This changes the original behavior where the struct
clk is only created for once when clock driver registers the clock to
CCF in the first place. The net change here is before commit
035a61c314 the struct clk pointer is unique for given hardware
clock, while after the commit the pointers returned by clk lookup calls
become different for the same hardware clock.
That said, the struct clk pointer comparing in the code doesn't work any
more. Call helper function clk_is_match() instead to fix the problem.

System restart mechanism has been changed with the introduction
of "kernel restart handler call chain support". The imx2 watchdog
based restart handler has been moved to the driver, and these
restart can be removed from the machine layer.
This patch cleans up the device tree version machine reset init with
mxc_arch_reset_init_dt and removes corresponding .restart handler,
for the .init_machine that can be handled by system default after
removing the mxc_arch_reset_init_dt, the .init_machine is also removed.

On imx6qdl, the ENET RMII and PTP clock can come from either internal
ANATOP/CCM or external clock source through pad GPIO_16. But in case
of the external clock source, bit IOMUXC_GPR1[21] needs to be cleared.
The patch adds the support for systems that use an external clock source
and distinguishes above two cases by checking if the PTP clock specified
in device tree is the one coming from the internal ANATOP/CCM.

When system enter suspend, we can set the DDR IO to
high-Z state to save DDR IOs' power consumption, this
operation can save many power(from ~26mA@1.5V to ~15mA@1.5V,
measured on i.MX6Q SabreSD board, R25) of DDR IOs. To
achieve that, we need to copy the suspend code to ocram
and run the low level hardware related code(set DDR IOs
to high-Z state) in ocram.
If there is no ocram space available, then system will
still do suspend in external DDR, hence no DDR IOs will
be set to high-Z.
The OCRAM usage layout is as below,

The imx6q_restart() works fine with normal reboot but will run into
problem with emergency reboot like sysrq-b. In that case, of_iomap()
gets called from interrupt context and hence triggers the BUG_ON in
__get_vm_area_node().
Actually, since commit c1e31d1 (ARM: imx: create
mxc_arch_reset_init_dt() for DT boot), imx6q/dl should try to use
mxc_restart() by calling mxc_arch_reset_init_dt() beforehand, where

Most of the information needed by cpufreq is stored in cpu0 DT node.
So cpu_dev must point to cpu0 device.

This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson:
"This branch contains mostly additions and changes to platform
enablement and SoC-level drivers. Since there's sometimes a
dependency on device-tree changes, there's also a fair amount of
those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad
Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving MSI
arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers"

The CLKO is widely used by imx6q board designs to clock audio codec.
Since most codecs accept 24 MHz frequency, let's initially set up CLKO
with OSC24M (cko <-- cko2 <-- osc). Then those board specific CLKO
setup for audio codec can be removed.
The board dts files also need an update on cko reference in codec node.

To improve the performance and power consumption add an i.MX6
specific L2 cache initialization.
This configuration is taken from Freescale's kernel patch
"ENGR00153601 [MX6]Adjust L2 cache parameter" [1]
with two additional improvements:
a) The L2X0_POWER_CTRL has only the two bits we set. So no need
to read the register before. Remove the register read done
in Freescale's patch.
b) In the L2X0_PREFETCH_CTRL register, besides the double linefill (bit[30]),
additionally enable the instruction and data prefetch (bit[29-28]).

This is the third and smallest of the SoC specific updates.
Changes include:
* SMP support for the Xilinx zynq platform
* Smaller imx changes
* LPAE support for mvebu
* Moving the orion5x, kirkwood, dove and mvebu platforms
to a common "mbus" driver for their internal devices.
It would be good to get feedback on the location of the "mbus"
driver. Since this is used on multiple platforms may potentially
get shared with other architectures (powerpc and arm64), it
was moved to drivers/bus/. We expect other similar drivers to
get moved to the same place in order to avoid creating more
top-level directories under drivers/ or cluttering up the
messy drivers/misc/ even more.

Function imx_anatop_get_digprog() that reads register ANADIG_DIGPROG is
called to identify silicon version. Users might query silicon version
earlier than regmap subsystem is ready. For example, imx6q clock driver
query revision in mx6q_clocks_init(), where regmap is not initialized
yet.
Change imx_anatop_get_digprog() to map anatop block and read
ANADIG_DIGPROG in the native way, so that the function can work at very
early stage.
While at it, let's move imx_print_silicon_rev() back to

This branch contains of devicetree changes for the Freescale i.MX platform.
The base patch of the branch changes the format of the dts files to a
slightly different format that makes it easier to do derivative board
definitions, but it also introduces a lot of churn in the process since
every line of the file is touched.
On top of that are a handful of the regular changes; enabling more boards
as DT-based instead of legacy board files (mx25pdk), enabling another
driver for devicetree and thus adding bindings (onewire), etc.
I'm not happy about the churn, and will likely not take it for other platforms
in the future.

The base patch of the branch changes the format of the dts files to a
slightly different format that makes it easier to do derivative board
definitions, but it also introduces a lot of churn in the process
since every line of the file is touched.
On top of that are a handful of the regular changes; enabling more
boards as DT-based instead of legacy board files (mx25pdk), enabling
another driver for devicetree and thus adding bindings (onewire), etc.
I'm not happy about the churn, and will likely not take it for other
platforms in the future."
