Add OMAP4460 OPP definitions for voltage and frequencies based on
OMAP4460 ES1.0 DM Operating Condition Addendum Version 0.1
The following exceptions are present:
* Smartreflex support is still on experimental mode: the gains and min
limits are currently pending characterization data. Currently OMAP4430 values
are used.
* Efuse offset for core OPP100-OV setting is not clear in documentation.
* IVA OPPs beyond OPP100 are disabled due to the delta between max OMAP4460
current requirements and Phoenix Max supply on VCORE2 in the default
configuration - boards which have supply which can support this should
explicitly call opp_enable and enable the same.
* MPU OPPs > OPPTURBO can easily be detected using a efuse burnt - currently
disabled pending clock changes to support DCC feature.

Every PMIC has it's own eccentricities, For example, one of the
PMIC has MSB set to 1 for a specific function - voltage enable!
using an hardcoded value specific for TWL when copied over to
such an implementation causes the system to crash as the MSB bit
was 0 and the voltage got disabled!.
Instead we use actual values and depend on the convertion routines
to abstract out the eccentricities of each PMIC.
With this, we can now move the voltages to a common location in
voltage.h as they are no longer dependent on PMICs and expect the
PMIC's conversion routines to set a cap if the voltage is out of
reach for the PMIC.

After commit 24d7b40a60 (ARM: OMAP2+:
PM: MPU DVFS: use generic CPU device for MPU-SS), OPPs are registered
using an existing CPU device, not the omap_device for MPU-SS.
First, fix the board file to use get_cpu_device() as required by the
above commit, otherwise custom OPPs will be added to the wrong device.
Second, the board files OPP init is called from the its init_machine
method, and the generic CPU devices are not yet created when
init_machine is run. Therefore OPP initialization will fail. To fix,
use a device_initcall() for the board file's OPP customization, and
make the device_initcall board-specific by using a machine_is check.

On n900 uart1 pins are not not used for uart, instead they are
used to connect to a cell modem over ssi. Looks like we're
currently missing these signal names for 3430 for some reason,
and only have some of them listed for 3630. Obviously the signals
are there for 3430 if n900 is using them and they are documented
in some TRMs.
Note that these will eventually be replaced by device tree
based pinctrl-single.c driver. But for now these are needed
to verify the SSI pins for devices like Nokia N900.

The runtime PM framework assumes that the hardware state of devices
when initialized is disabled. For all omap_devices, we idle/disable
device by default. However, the console uart uses a "no idle" option
during omap_device init in order to allow earlyprintk usage to work
seamlessly during boot.
Because the hardware is left partially enabled after init (whatever
the bootloader settings were), the omap_device should later be fully
initialized (including mux) and the runtime PM framework should be
told that the device is active, and not disabled so that the hardware
state is in sync with runtime PM state.
To fix, after the device has been created/registered, call
omap_device_enable() to finialize init and use pm_runtime_set_active()
to tell the runtime PM core the device is enabled.
Tested on 2420/n810, 3530/Overo, 3530/Beagle, 3730/OveroSTORM,
3730/Beagle-xM, 4460/PandaES.

On OMAP34xx/35xx, and OMAP36xx chips with ES < 1.2, if the PER
powerdomain goes to OSWR or OFF while CORE stays at CSWR or ON, or if,
upon chip wakeup from OSWR or OFF, the CORE powerdomain goes ON before
PER, the UART3/4 FIFOs and McBSP2/3 SIDETONE memories will be
unusable. This is erratum i582 in the OMAP36xx Silicon Errata
document.
This patch implements one of several parts of the workaround: the
addition of the wakeup dependency between the PER and WKUP
clockdomains, such that PER will wake up at the same time CORE_L3
does.
This is not a complete workaround. For it to be complete:
1. the PER powerdomain's next power state must not be set to OSWR or
OFF if the CORE powerdomain's next power state is set to CSWR or
ON;
2. the UART3/4 FIFO and McBSP2/3 SIDETONE loopback tests should be run
if the LASTPOWERSTATEENTERED bits for PER and CORE indicate that
PER went OFF while CORE stayed on. If loopback tests fail, then
those devices will be unusable until PER and CORE can undergo a
transition from ON to OSWR/OFF and back ON.

Previously the code only acquired spinlock after increasing / decreasing
the usecount value, which is wrong. This leaves a small window where
a task switch may occur between the check of the usecount and the actual
wakeup / sleep of the domain. Fixed by moving the spinlock locking before
the usecount access. Left the usecount as atomic_t if someone wants an
easy access to the parameter through atomic_read.

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal)
changed the interrupts to allow enabling sparse IRQ, but
accidentally added the omap3 INTC base to the local IRQ.
This causes the following:
twd: can't register interrupt 45 (-22)
twd_local_timer_register failed -22
The right fix is to not add any base, as it is a local
timer. For the OMAP44XX_IRQ_LOCALWDT we had defined earlier
there are no users, so no need to fix that.

As suggested by Andrew Morton:
This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.
Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.
lets sort all our select statements alphanumerically. This commit was
created by the following perl:
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
It found two duplicates:
Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry
and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

This series a couple bug fixes and a couple fixes that make this

The 'get_cpu_device' patch is needed due to a change in the OMAP
OMAP PM core code which enforces use of get_cpu_device() instead of
a deprecated OMAP-specific API.
The usage of plat/*.h headers breaks single zImage, so platforms are
cleaning up and/or removing plat/*.h so the driver needs to be fixed
accordingly.

integration issues, and bugs after the arm-soc merges.
* tag 'omap-for-v3.7-rc1/fixes-hwmod-clock-signed-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP4/AM335x: hwmod: fix disable_module regression in hardreset handling
ARM: OMAP3: fix workaround for EMU clockdomain
ARM: OMAP: omap3evm: fix new sparse warning
ARM: OMAP2+: hwmod data: Fix PMU interrupt definitions
ARM: am33xx: clk: Update clkdev table to add mcasp alias
Commit eb05f69129 ("ARM: OMAP: hwmod:
partially un-reset hwmods might not be properly enabled") added code
to skip the IP block disable sequence if all of the block's hardreset
lines weren't asserted. But this did not handle the case when no
hardreset lines were associated with a module, which is the general
case. In that situation, the IP block disable would be skipped. This
is likely to cause PM regressions.
So, modify _omap4_disable_module() and _am33xx_disable_module() to
only bail out early if there are any hardreset lines asserted. And
move the AM33xx test above the actual module disable code to ensure
that the behavior is consistent.

Commit b71c721 (ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU
clockdomain idle problems) added a workaround for the EMU clock domain on
OMAP3/4 devices to prevent the clock domain for transitioning while it is
in use.
In the proposed patch [1] code was added to the omap3xxx_clkdm_clk_enable()
and omap3xxx_clkdm_clk_disable() functions to check for the flag
CLKDM_MISSING_IDLE_REPORTING and perform the appropriate action. However, in the
merged patch it appears that this code was added to the omap2_clkdm_clk_enable()
and omap2_clkdm_clk_disable() functions by mistake.

driver support recently added OMAP-based SoCs.
The 'get_cpu_device' patch is needed due to a change in the OMAP
OMAP PM core code which enforces use of get_cpu_device() instead of
a deprecated OMAP-specific API.
The usage of plat/*.h headers breaks single zImage, so platforms are
cleaning up and/or removing plat/*.h so the driver needs to be fixed
accordingly.
This series is based on the merge of Rafael's pm-for-3.7-rc1 tag into
Linus' master branch: commit 16642a2e7b.

This contains pretty many small commits covering fairly large range of
files in sound/ directory. Partly because of additional API support
and partly because of constantly developed ASoC and ARM stuff.
Some highlights:
- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later
- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)
- HD-audio controller got the support of runtime PM and the support of
D3 clock-stop. Also changing the power_save option in sysfs kicks
off immediately to enable / disable the power-save mode.
- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in HD-audio
are continued cleanups and standardization for the generic auto
parser and bug fixes (HBR, device-specific fixups), in addition to
the support of channel-map API.
- Addition of ASoC bindings for the compressed API, used by the
mid-x86 drivers.
- Lots of cleanups and API refreshes for ASoC codec drivers and
DaVinci.
- Conversion of OMAP to dmaengine.
- New machine driver for Wolfson Microelectronics Bells.
- New CODEC driver for Wolfson Microelectronics WM0010.
- Enhancements to the ux500 and wm2000 drivers
- A new driver for DA9055 and the support for regulator bypass mode.

Currently, a dummy omap_device is created for the MPU sub-system so
that a device node exists for MPU DVFS. Specifically, for the
association of MPU OPPs to a device node, and so that a voltage
regulator can be mapped to a device node.
For drivers to get a handle to this device node, an OMAP-specific API
has been used. However, the kernel already has device nodes for the
CPU(s) in the system, so we can use those instead of an OMAP-specific
dummy device and then drivers (like OMAP CPUfreq) can use generic
APIs.
To use the existing CPU device nodes, modify the OPP creation and
regulator registration to use the CPU0 device node for registraion.
NOTE: this patch always uses CPU0 as the device node. On all
OMAPs today, MPU DVFS scales all CPUs together, so this will
not be a problem, but this assumption will need to be changed
if independently scalable CPUs are introduced.
