ARM: OMAP2+: hwmod: Change hardreset soc_ops for AM43XX

am43xx reset register layout is more similar to am33xx than omap4 so
use the am33xx functions for hwmod hardreset soc_ops rather than the
currently used omap4 functions. Without this, assert_hardreset and
deassert_hardreset will not work on am43xx.

ARM: dts: Enable twl4030 off-idle configuration for selected omaps

N900 now seems to shut down the external oscillator when hitting
off-idle.

And Beagle XM seems to have OSC_EN pin connected to allow shutting
down the oscillator looking at the schematics. The oscillator
output is cut off in off-idle and you can monitor it from R56 on
the bottom side of the board near the power jack. Note that for
beagle we need to also enable the UART wake-up event, the others
have that enabled in earlier patches.

OMAP37XX EVM (TMDSEVM3730) does not seem to have twl4030 clken
pin connected, so there is no point trying to enable shutting
down of the oscillator on it for the extra latency it adds.

Merge tag 'for-v3.16-rc/omap-fixes-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.16/fixes

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.

Basic build, boot, and PM test logs are available here:

ARM: dts: omap5: Update CPU OPP table as per final production Manual

As per the Final production Data Manual for OMAP5432,
SWPS050F(APRIL 2014)

There are only two OPPs - 1GHz and 1.5GHz. the older OPP_LOW has been
completely descoped. The Nominal voltages are still correct though.
However, expectation for final production configuration is operation
with Adaptive Body Bias (ABB) and Adaptive Voltage Scaling Class 0
operation.

There are no IDcode or version change information encoded to
programmatically detect this and software is supposed to NOT use
OPP_LOW(500MHz) anymore for all devices (legacy and production
samples).

ARM: OMAP2+: Fix parser-bug in platform muxing code

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

Patch should apply to linus' latest master down to rather old linux-2.6
trees.

irqchip: armada-370-xp: Mask all interrupts during initialization.

Until now, the irq-armada-370-xp irqchip driver was not masking all
interrupts at initialization. While in most cases this is not a
problem because the bootloader has probably masked all interrupts, it
becomes a problem when you use kexec: you're in kernel A, with many
interrupts enabled, and then kexec into kernel B, without going
through the bootloader. So during the boot process, if an interrupt
occurs while the corresponding driver has not been loaded, you would
get spurious interrupts.

This commit fixes that by ensuring all interrupts are properly masked
when the irqchip driver is initialized. Note that interrupt masking
takes place at two level: at the global level (main_int_base) and at
the per-CPU level (per_cpu_int_base).

there.

Fix by enabling the new options as needed.
