On OMAP SOCs using PL310 controllers, power_ctrl register is not
accessible from non-secure software even on PL310 versions which
support it. The secure code takes care of setting it up correctly
and power transitions are proven on these devices.
For example, AM437x has L2C-310 version r3p3 and ROM code on that
device does not support writing to L2C-310 power control register.
The L2C driver, however, tries writing to this register for all
revisions >= r3p0.
This leads to a warning dump on boot which leads most users to believe
that L2 cache is non-functional.
Since the problem is understood, and cannot be addressed through
software, replace the warning with a pr_info() while maintaining the
WARN_ON() for other truly unexpected scenarios.

The DSP platform device for TI DSP/Bridge is currently
created unconditionally whenever CONFIG_TIDSPBRIDGE is
enabled. This device should only be created on OMAP34xx/
OMAP36xx SoCs, and not for other OMAP3 derived SoCs or when

Pull ARM SoC fixes from Olof Johansson:
"This week's arm-soc fixes:
- A set of of OMAP patches that we had missed Tony's pull request of:
* Reset fix for am43xx
* Proper OPP table for omap5
* Fix for SoC detection of one of the DRA7 SoCs
* hwmod updates to get SATA and OCP to work on omap5 (drivers
merged in 3.16)
* ... plus a handful of smaller fixes
- sunxi needed to re-add machine specific restart code that was
removed in anticipation of a watchdog driver being merged for 3.16,
and it didn't make it in.
- Marvell fixes for PCIe on SMP and a big-endian fix.
- A trivial defconfig update to make my capri test board boot with
bcm_defconfig again.
... and a couple of MAINTAINERS updates, one to claim new Keystone
drivers that have been merged, and one to merge MXS and i.MX (both
Freescale platforms).
The largest diffs come from the hwmod code for omap5 and the re-add of
the restart code on sunxi. The hwmod stuff is quite late at this
point but it slipped through cracks repeatedly while coming up the
maintainer chain and only affects the one SoC so risk is low"

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)
Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
eventually get rid of CACHE_PL310, surround these errata options with an
if CACHE_L2X0 conditional rather than repeating the dependency against
each.

Commit d941f86fad ("ARM: l2c: AM43x: add L2 cache support") enabled
the L2 cache support for the am43xx SoC, but caused a build regression
when the driver for that cache controller is disabled:
arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
:(.init.text+0xb20): undefined reference to `omap_l2_cache_init'
This did not happen for OMAP4, which has the same call, but enables
the l2x0 driver unconditionally. We could do the same thing for
am43xx, but it seems better to allow turning it off and make the
code work in either case.
This adds an inline wrapper for omap_l2_cache_init for the disabled
case, and removes the 'select' from OMAP4 so it becomes a user
visible option.

Fix a parser-bug in the omap2 muxing code where muxtable-entries will be
wrongly selected if the requested muxname is a *prefix* of their
m0-entry and they have a matching mN-entry. Fix by additionally checking
that the length of the m0_entry is equal.
For example muxing of "dss_data2.dss_data2" on omap32xx will fail
because the prefix "dss_data2" will match the mux-entries "dss_data2" as
well as "dss_data20", with the suffix "dss_data2" matching m0 (for
dss_data2) and m4 (for dss_data20). Thus both are recognized as signal
path candidates:
Relevant muxentries from mux34xx.c:
_OMAP3_MUXENTRY(DSS_DATA20, 90,
"dss_data20", NULL, "mcspi3_somi", "dss_data2",
"gpio_90", NULL, NULL, "safe_mode"),
_OMAP3_MUXENTRY(DSS_DATA2, 72,
"dss_data2", NULL, NULL, NULL,
"gpio_72", NULL, NULL, "safe_mode"),
This will result in a failure to mux the pin at all:
_omap_mux_get_by_name: Multiple signal paths (2) for dss_data2.dss_data2

Two OMAP hwmod patches for early v3.16-rc kernels.
There's one OMAP SoC integration fix for the AM43xx SoC, without
which, IP blocks can't be placed into hard-reset.
There is also one OMAP5 SoC data addition patch that should have gone
in for v3.16. Normally I wouldn't send this as part of an -rc series,
since it's not technically a fix. But I'd like to make an exception in
this case because:
- it's intended to go in very early in the v3.16-rc series (or even
pre-rc1);
- it's a fairly small change;
- the impact is limited to a single SoC and a single device;
- the only reason that it didn't go in earlier is because it "slipped
through the cracks," rather than for any technical reason.

Upon shutdown, the pwm-backlight driver will now power off the

concise GPIO handling.
A large chunk of these changes also converts platforms to use the
lookup mechanism rather than relying on the global number space to

Duty Cycle Correction(DCC) needs to be enabled if the MPU is to run at
frequencies beyond 1.4GHz for OMAP5, DRA75x, DRA72x.
MPU DPLL has a limitation on the maximum frequency it can be locked
at. Duty Cycle Correction circuit is used to recover a correct duty
cycle for achieving higher frequencies (hardware internally switches
output to M3 output(CLKOUTHIF) from M2 output (CLKOUT)).
For further information, See the note on OMAP5432 Technical Reference
Manual(SWPU282U) chapter 3.6.3.3.1 "DPLLs Output Clocks Parameters",
and also the "OMAP543x ES2.0 DM Operating Conditions Addendum v0.5"
chapter 2.1 "Micro Processor Unit (MPU)". Equivalent information is
present in relevant DRA75x, 72x documentation(SPRUHP2E, SPRUHI2P).

Pull ARM updates from Russell King:
- Major clean-up of the L2 cache support code. The existing mess was
becoming rather unmaintainable through all the additions that others
have done over time. This turns it into a much nicer structure, and
implements a few performance improvements as well.
- Clean up some of the CP15 control register tweaks for alignment
support, moving some code and data into alignment.c
- DMA properties for ARM, from Santosh and reviewed by DT people. This
adds DT properties to specify bus translations we can't discover
automatically, and to indicate whether devices are coherent.
- Hibernation support for ARM
- Make ftrace work with read-only text in modules
- add suspend support for PJ4B CPUs
- rework interrupt masking for undefined instruction handling, which
allows us to enable interrupts earlier in the handling of these
exceptions.
- support for big endian page tables
- fix stacktrace support to exclude stacktrace functions from the
trace, and add save_stack_trace_regs() implementation so that kprobes
can record stack traces.
- Add support for the Cortex-A17 CPU.
- Remove last vestiges of ARM710 support.
- Removal of ARM "meminfo" structure, finally converting us solely to
memblock to handle the early memory initialisation.

Pull USB driver updates from Greg KH:
"Here is the big USB driver pull request for 3.16-rc1.
Nothing huge here, but lots of little things in the USB core, and in
lots of drivers. Hopefully the USB power management will be work
better now that it has been reworked to do per-port power control
dynamically. There's also a raft of gadget driver updates and fixes,
CONFIG_USB_DEBUG is finally gone now that everything has been
converted over to the dynamic debug inteface, the last hold-out
drivers were cleaned up and the config option removed. There were
also other minor things all through the drivers/usb/ tree, the
shortlog shows this pretty well.
All have been in linux-next, including the very last patch, which came
from linux-next to fix a build issue on some platforms"

"The bulk of this branch is updates for Renesas Shmobile. They are
still doing some enablement for classic boards first, and then come up
with DT bindings when they've had a chance to learn more about the
hardware. Not necessarily a bad way to go about it, and they're
looking at moving some of the temporary board code resulting from it
to drivers/staging instead to avoid the churn here.
As a result of the shmobile clock cleanups, we end up merging quite a
bit of SH code here as well. We ended up merging it here instead of
in the cleanup branch due to the other board changes depending on it"

L2 cache initialization for OMAP4 redundantly sets the cache policy to
Round-Robin. This is not needed since thats the PL310 default anyway.
Removing this reduces the number of platform specific aux control
settings.

Avoid reading directly from the L2 registers in platform code. The L2
code will have already saved the register values itself into the
l2x0_saved_regs structure, so platform code should just move these
values to where they're required.
This is safe because the L2x0 will have been initialised by an early
initcall, whereas the OMAP4 PM code is initialised late.

Since we now always enable NS access to the unlock registers, this can
be removed from OMAP4. Remove the NS access bit for the interrupt
registers from OMAP4 as well - nothing in the kernel accesses that yet,
and we can add it in core code when we have the need.

The cache size should already be present in the L2 cache auxiliary
control register: it is part of the integration process to configure
the hardware IP. Most platforms get this right, yet still many
cargo-cult program, and assume that they always need specifying to
the L2 cache code. Remove them so we can find out which really need
this.

Since we now automatically enable early BRESP in core L2C-310 code when
