Drivers using pinctrl-single,pins have #pinctrl-cells = <1>, while
pinctrl-single,bits need #pinctrl-cells = <2>.
Note that this patch can be optionally applied separately from the
driver changes as the driver supports also the legacy binding without
#pinctrl-cells.

Some omap5 variants have more than 2GB of memory available as

The ID pin GPIO comes from the PMIC. Let's configure it as a GPIO
for the driver to use, and also make sure the PMIC GPIO pin muxing
is correct. The PMIC pad1 and 2 values for omap5-uevm and igepv5 are
0x5a and 0x1b, we only need to clear bit 2 in pad1 register to make
the ID pin GPIO work.

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:
"Node /memory has a reg or ranges property, but no unit name"
The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it should not have
functional changes.

These are all the updates to device tree files for 32-bit platforms,
which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
changesets, 450 files changed, 23340 insertions, 5216 deletions.
The three platforms that are added with the "soc" branch are here as well,
and we add some related machine files:
- For Aspeed AST2400/AST2500, we get the evaluation platform and
the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
- For Oxnas 810SE, the Western Digital "My Book World Edition"
is added as the only platform at the moment.
- For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
are supported
On the ARM Realview development platform, we now support all machines
with device tree, previously only the board files were supported, which
in turn will likely be removed soon.
Qualcomm IPQ4019 is the second generation ARM based "Internet Processor",

The L3 Error handling on OMAP5 for the most part is very similar
to that of OMAP4, and had leveraged common data structures and
register layout definitions so far. Upon closer inspection, there
are a few minor differences causing an incorrect decoding and
reporting of the master NIU upon an error:
1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies
11 bits on OMAP5 as against 8 bits on OMAP4, with the master
NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR
field.
2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3
input sources on OMAP5. The common DEBUGSS source is at a
different input on each SoC.
Fix the above issues by using a OMAP5-specific compatible property
and using SoC-specific data where there are differences.

- A branch with DT updates for Freescale i.MX. including some shuffling from

from Tero Kristo <t-kristo@ti.com>.
This sets gets us into a better position for further clean-up:
- Gets PRCM code closer to being device drivers
- Allows to move the remainig clock code to drivers/clk for v4.2
- Starts enforcing interconnect hierarchy in the SoC specific .dts
files to enforce device drivers are only accesing registers in
the related hardware module
This patchset has seen quite a few revisions but did not come into
mergeable shape until recently. As other patchsets for clock specific
device drivers depend on this, it would be good to get this merged
although it's a bit late for the v4.1 merge window.
Note that as the device entries in the .dts files are moved around,
this is based on earlier non-urgent fixes to avoid a non-trivial
merge conflict.

Merge tag 'omap-for-v4.1/prcm-dts' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/late
Pull "Clean-up for omap PRCM (Power Reset Clock Management) and interconnects" from Tony Lindgren
Patches originally from Tero Kristo <t-kristo@ti.com>.
This sets gets us into a better position for further clean-up:
- Gets PRCM code closer to being device drivers
- Allows to move the remainig clock code to drivers/clk for v4.2
- Starts enforcing interconnect hierarchy in the SoC specific .dts
files to enforce device drivers are only accesing registers in
the related hardware module
This patchset has seen quite a few revisions but did not come into
mergeable shape until recently. As other patchsets for clock specific
device drivers depend on this, it would be good to get this merged
although it's a bit late for the v4.1 merge window.
Note that as the device entries in the .dts files are moved around,
this is based on earlier non-urgent fixes to avoid a non-trivial
merge conflict.

irqchip core change for v4.1 (round 3) from Jason Cooper
Purge the gic_arch_extn hacks and abuse by using the new stacked domains
NOTE: Due to the nature of these changes, patches crossing subsystems have
been kept together in their own branches.

This patch creates the l4_cfg and l4_wkup interconnects for OMAP5, and
moves some of the generic peripherals under it. System control module
support is added to the device tree also, and the existing SCM related
functionality is moved under it.

OMAP4/5 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 WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.

in the thermal zone polling intervals. OMAP5 has a different counter

Without this patch, the polling interval information is simply ignored,

In order to handle errata I688, a page of sram was reserved by doing a
static iotable map. Now that we use gen_pool to manage sram, we can
completely remove all of these static mappings and use gen_pool_alloc()
to get the one page of sram space needed to implement errata I688.
omap_bus_sync will be NOP until SRAM initialization happens.

The RFBI node for OMAP DSS was left out when adding the rest of the DSS

However, it seems that if there is a HWMOD for a device, we also need a
DT node for it. Otherwise, at boot, we get:

There are only two OPPs - 1GHz and 1.5GHz. the older OPP_LOW has been

However, expectation for final production configuration is operation
with Adaptive Body Bias (ABB) and Adaptive Voltage Scaling Class 0

As with previous release, this continues to be among the largest branches
we merge, with lots of new contents.
New things for this release are among other things:
- DTSI contents for the new SoCs supported in 3.16 (see SoC pull request)
- Qualcomm APQ8064 and APQ8084 SoCs and eval boards
- Nvidia Jetson TK1 development board (Tegra T124-based)
Two new SoCs that didn't need enough new platform code to stand out
enough for me to notice when writing the SoC tag, but that adds new DT
contents are:
- TI DRA72
- Marvell Berlin 2Q

Add the mailbox device DT node for OMAP5 SoC. The OMAP5 mailbox
IP is identical to that used in OMAP4.
The OMAP5 hwmod data no longer publishes the module address space,
so this patch fixes the WARN_ON backtrace associated with the
following trace during the kernel boot:
"omap_hwmod: mailbox: doesn't have mpu register target base".
Otherwise we get a warning like this:
WARNING: CPU: 0 PID: 1 at arch/arm/mach-omap2/omap_hwmod.c:2538 _init+0x1c0/0x3dc()
