Daniel Lezcano f79b5d8abf ARM: OMAP3: cpuidle - remove the 'valid' field
With the previous changes all the states are valid, except the last
state which is now handled at runtime by next_valid_state() based on
the errata flags.

Daniel Lezcano 92b18d9753 ARM: OMAP3: cpuidle - remove errata check in the init function
The errata check is done in the next_valid_state function, no need to check
that in the omap3_idle_init function.

Daniel Lezcano 231900afba ARM: OMAP3: cpuidle - remove rx51 cpuidle parameters table
As suggested, this table is an optimized version for rx51 and we
remove it in order to consolidate the cpuidle code between omap3
and omap4, we remove this specific data definition which is used
to override the default omap3 latencies but at the cost of extra
code and complexity.

In order to not lose the values which probably took time to be
measured, the table is converted into a comment with an array
description.

We are storing the 'omap4_idle_data' in the private data field
of the cpuidle device. As we are using this variable only in this file,
that does not really make sense. Let's use the global variable directly.

least one of the CORE clockdomains from going idle, which causes PM

Paul Walmsley 2221b5cddc ARM: OMAP2+: hwmod: add support for link registration
Add support for direct IP block interconnect ("link") registration to
the hwmod code via a new function, omap_hwmod_register_links().  This
will replace direct registration of hwmods, and a subsequent patch
will remove omap_hwmod_register().

This change will allow a subsequent patch to remove the hwmod data
link arrays.  This will reduce the size of the hwmod static data and
also make it easier to generate the data files.  It will also make it
possible to share some of the struct omap_hwmod records across
multiple SoCs, since the link array pointers will be removed from the
struct omap_hwmod.

The downside is that boot time will increase.  Minimizing boot time
was the reason why the link arrays were originally introduced.
Removing them will require extra computation during boot to allocate
memory and associate IP blocks with their interconnects.  However,
since the current kernel development focus is on reducing the number
of lines in arch/arm/mach-omap2/, boot time impact is now seemingly
considered a lower priority.

This patch contains additional complexity to reduce the number of
memory allocations required for this change.  This reduces the boot
time impact: total hwmod link registration time was ~ 2655
microseconds with a simple allocation strategy, but is now ~ 549
microseconds[1] with the approach taken by this patch.

1. Measured on a BeagleBoard 35xx @ 500MHz MPU/333 MHz CORE, average
   of 7 samples.  Total uncertainty is +/- 61 microseconds.

Paul Walmsley 747834ab83 ARM: OMAP2+: hwmod: revise hardreset behavior
Change the way that hardreset lines are handled by the hwmod code.
Hardreset lines are generally associated with initiator IP blocks.
Prior to this change, the hwmod code expected to control hardreset
lines itself, asserting them on shutdown and deasserting them upon
enable.  But driver authors inside TI have commented to us that their
drivers require direct control over these lines.  Unfortunately, these
drivers haven't been posted publicly yet, so it's hard to determine
exactly what is needed, a priori.  This change attempts to set forth
some reasonable semantics that should be an improvement over the
current code.

The semantics implemented by this patch are as follows:

- If the hwmod is not marked with HWMOD_INIT_NO_RESET, then assert all
  associated hardreset lines during IP block setup.  This is intended
  to place the IP blocks into a known state that will not interfere
  with other devices during kernel boot.

- IP blocks with hardreset lines will not be automatically enabled or
  idled during setup.  Instead, they will be left in the INITIALIZED
  state.

- When the hwmod code is asked to enable, idle, or shutdown an IP
  block with asserted hardreset lines, the hwmod code will do nothing.
  The driver integration code must do the remaining work needed to
  control these IP blocks.  Once this driver integration code is posted
  to the lists, hopefully we can consolidate it and move it inside the
  hwmod code.

Custom reset functions for IP blocks with hardreset lines still should
be supported and are strongly endorsed.  It is intended that every
subsystem with hardreset lines should have a custom reset function
that can place their subsystem into quiescent idle with the hardreset
lines deasserted.

This reverts most of commit 5365efbe29
("OMAP: hwmod: Add hardreset management support").  Later code
reorganizations caused the sequencing of the code from this patch to
be changed, anyway.

Paul Walmsley 30e105c000 ARM: OMAP2+: hwmod: revise the IP block reset process
Revise the IP block reset process.  This patch ensures that the
OCP_SYSCONFIG registers are reloaded after a custom reset.  Since
OCP_SYSCONFIG bits are cleared during reset, they should be
reprogrammed unless the IP block is being left in reset.  (The only IP
blocks that are left in reset are IP blocks with hardreset lines and
no custom reset function.)  If the IP block is left in reset, then it
is inaccessible to the MPU, and an access to the OCP_SYSCONFIG
register will cause an abort.

This version incorporates comments from Omar Ramirez Luna
<omar.ramirez@ti.com> to skip the OCP_SYSCONFIG access after asserting
hardreset lines.  This allows the MMU (IOMMU) IP block, which has
both hardreset lines and an OCP_SYSCONFIG register.

Also, ignore _ocp_softreset() errors if the IP block doesn't include a
softreset bit.  This is needed since a subsequent patch will start
taking the return value of the _reset() function seriously.

After this change, the hwmod code will reset processor IPs at the

example, if the IVA device driver code wishes to place one of the
sequencer cores into reset, while leaving the other active, it must do
so itself by calling the appropriate PRM functions.

Thanks to Jarkko Nikula for some comments on the sscanf() warnings.
It seems that the kernel sscanf() ignores the field width anyway for the
%d format, so those changes have been dropped from this second version.

Thanks to Daniel Marjamäki <daniel.marjamaki@gmail.com> for pointing
out that a variable was unnecessarily marked static in the
board-omap3evm.c change.

Santosh Shilimkar 5ae256dcd9 ARM: OMAP: serial: Fix the ocp smart idlemode handling bug
The current serial UART code, while fidling with ocp idlemode bits,
forget about the smart idle wakeup bit even if it is supported by
UART IP block. This will lead to missing the module wakeup on OMAP's
where the smart idle wakeup is supported.

This was the root cause of the console sluggishness issue, I have been
observing on OMAP4 devices and also can be potential reason for some
other UART wakeup issues.

Govindraj.R bce492c04b ARM: OMAP2+: UART: Fix incorrect population of default uart pads
Commit (7496ba3  ARM: OMAP2+: UART: Add default mux for all uarts)
wrongly added muxing of default pads for all uarts. This causes
breakage on multiple boards using uart pins for alternate functions.

For example, on zoom3 random oopses can be seen with nfsroot as
the smsc911x ethernet FIFO timings on GPMC bus are controlled
by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these
pads to uart4 functionality as commit 7496ba3 was doing.

Not all boards tend to use all uarts and most of unused uart pins
are muxed for other purpose. This commit breaks the modules which
where trying to use unused uart pins on their boards.

So remove the default pad muxing. Note that this is not a complete
fix, as we now rely on bootloader set muxing for the uart wake-up
events. Further patching is needed to enable wake-up events for
uarts that are already muxed to uart mode.

Paul Walmsley 355f8eee48 ARM: OMAP2+: GPMC: resolve type-conversion warning from sparse
arch/arm/mach-omap2/gpmc.c passes a return value from ioremap() as the
fifth argument to request_irq() without casting it.  This causes
sparse to generate the following warning:

arch/arm/mach-omap2/gpmc.c:759:63: warning: incorrect type in argument 5 (different address spaces)
arch/arm/mach-omap2/gpmc.c:759:63:    expected void *dev
arch/arm/mach-omap2/gpmc.c:759:63:    got void [noderef] <asn:2>*static [toplevel] [assigned] gpmc_base

It turns out that it's not necessary to pass this.  gpmc_base is a
file-scoped static variable, the ISR is located in the same file ... and
the ISR doesn't even touch the passed-in variable.  So, just replace it with
NULL in request_irq().

Archit Taneja 1f5e6247ca ARM: OMAP2/3: VENC hwmods: Remove OCPIF_SWSUP_IDLE flag from VENC slave interface
The clocks for all DSS slave interfaces were recently changed to "dss_ick" on
OMAP2 and OMAP3, this clock can be autoidled by PRCM. The VENC interface
previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and
hence the OCPIF_SWSUP_IDLE flag was needed.

Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is
now "dss_ick".  This allows the PRCM hardware to autoidle the VENC
interface clocks when they are not active, rather than relying on the
software to do it, which can keep the interface clocks active
unnecessarily.

This reverts commit f9a2f9c3fa.  This
commit caused a regression in the I2C hwmod reset on OMAP2/3/4,
logging messages similar to these during boot:

[    0.200378] omap_hwmod: i2c1: softreset failed (waited 10000 usec)
[    0.222076] omap_hwmod: i2c2: softreset failed (waited 10000 usec)

While the original patch was intended to fix some reset-related timing
issues, it's believed that these problems were actually fixed by
commit 2800852a07 ("ARM: OMAP2+: hwmod:

Fernando Guzman Lugo d99de7f552 ARM: OMAP2+: hwmod: add softreset delay field and OMAP4 data
Due to HW limitation, some IPs should not be accessed just after a
softreset. Since the current hwmod sequence is accessing the sysconfig
register just after the reset, it might lead to OCP bus error in
that case.

Add a new field in the sysconfig structure to specify a delay in usecs
needed after doing a softreset.

In the case of the ISS and FDIF modules, the L3 OCP port will be
disconnected upon a SW reset. That issue was confirmed with HW simulation
and an errata should be available soon. The HW recommendation to avoid
that is to wait for 100 OCP clk cycles, before accessing the IP.

Considering the worse case (OPP50), the L3 bus will run at 100 MHz,
so a 1 usec delay is needed. Add an x2 margin to be safe.

Linus Torvalds 314489bd4c ARM: SoC fixes for 3.4-rc2
A bunch of fixes for regressions (and a few other problems) in 3.4-rc1:
 
 * Fix for regression of mach/io.h cleanup on platforms with PCI or PCMCIA
   (adding back the include file on those for now)
 * AT91 fixes for usb and spi
 * smsc911x ethernet fixes for i.MX
 * smsc911x fixes for OMAP
 * gpio fixes for Tegra
 * A handful of build error and warning fixes for various platforms
 * cpufreq kconfig dependencies, build and lowlevel debug fixes for
   Samsung platforms
 
 In other words, more or less the regular collection of -rc1/2 type
 material. A few of them, in particular the smsc911x for OMAP series, aren't
 technically regressions for 3.4, but they're valid fixes and we're still
 relatively early in the rc cycle so it seems appropriate to include them.

Some modules doesn't have SYSC_HAS_ENAWAKEUP bit available (ex: usb

Configure sysc if SYSC_HAS_ENAWAKEUP is available and for other cases
try enabling/disabling wakeup from mux_pad pins.

Commit b1cbdb00d ("OMAP: clockdomain: Wait for powerdomain to be ON
when using clockdomain force wakeup") was assuming that
pwrdm_state_switch() does wait for the powerdomain transition which is
not the case.  The missing wait for the powerdomain transition
violates the sequence which the hardware expects, which causes power
management failures on some devices.

Fix this API by adding the pwrdm_wait_transition().

Grazvydas Ignotas ac387330a6 ARM: OMAP3xxx: clock data: fix DPLL4 CLKSEL masks
Commit 2a9f5a4d45 "OMAP3 clock: remove unnecessary duplicate of dpll4_m2_ck,
added for 36xx" consolidated dpll4 clock structures between 34xx and 36xx,
but left 34xx CLKSEL masks for most dpll4 related clocks, which causes
clock code to not behave correctly when booting on DM3730 with higher
(36xx only) divisors set:
[    0.000000] WARNING: at arch/arm/mach-omap2/clkt_clksel.c:375 omap2_init_clksel_parent+0x104/0x114()

[    0.000000] clock: Could not find fieldval 0 for clock dpll4_m3_ck parent dpll4_ck

Fix this by switching to 36xx masks, as valid divisors will be limited
by clksel_rate lists.

Grazvydas Ignotas 26c547fd13 ARM: OMAP3xxx: HSMMC: avoid erratum workaround when transceiver is attached
If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems
2.1.1.128 erratum doesn't apply and there is no data corruption,
probably because of different signal timing. The workaround for this
erratum disables multiblock reads, which causes dramatic loss of
performance (over 75% slower), so avoid it when transceiver is present.

Linus Torvalds 820d41cf0c ARM: cleanups of io includes
Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes,
 moving some of the oft-repeated macros to a common location and removing a bunch of
 boiler plate. This is another step closer to a common zImage for multiple platforms.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

Linus Torvalds 34800598b2 ARM: driver specific updates
These are all specific to some driver. They are typically the platform
 side of a change in the drivers directory, such as adding a new driver
 or extending the interface to the platform. In cases where there is no
 maintainer for the driver, or the maintainer prefers to have the
 platform changes in the same branch as the driver changes, the patches
 to the drivers are included as well.
 
 A much smaller set of driver updates that depend on other branches
 getting merged first will be sent later.
 
 The new export of tegra_chip_uid conflicts with other changes in fuse.c.
 In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with
 the cleanup of the interrupt handling of that driver.

Linus Torvalds 1bfecd9358 ARM: board specific updates
These changes are all specific to one board only. We're trying to keep
 the number of board files low, but generally board level updates are
 ok on platforms that are working on moving towards DT based probing,
 which will eventually lead to removing them.
 
 The board-ams-delta.c board file gets a conflict between the removal of
 ams_delta_config and the addition of a lot of other data. The Kconfig
 file has two changes in the same line, and in exynos, the power domain
 cleanup conflicts with the addition of the image sensor device.

   - Getting rid of the NO_IRQ crap from AMBA primecell stuff.

Nishanth Menon 9fa2df6b90 ARM: OMAP2+: OPP: allow OPP enumeration to continue if device is not present
On platforms such as OMAP3, certain variants may not have IVA, SGX
or some specific component. We currently have a check to aid fixing
wrong population of OPP entries for issues such as typos. This however
causes a conflict with valid requirement where the SoC variant does
not actually have the module present.

So, reduce the severity of the print to a debug statement and skip
registering that specific OPP, but continue down the list.

Santosh Shilimkar 68523f4233 ARM: OMAP4: Workaround the OCP synchronisation issue with 32K synctimer.
On OMAP4, recently a synchronisation bug is discovered by hardware
team, which leads to incorrect timer value read from 32K sync timer
IP when the IP is comming out of idle.

The issue is due to the synchronization methodology used in the SYNCTIMER IP.
The value of the counter register in 32kHz domain is synchronized to the OCP
domain register only at count up event, and if the OCP clock is switched off,
the OCP register gets out of synch until the first count up event after the
clock is switched back -at the next falling edge of the 32kHz clock.

Further investigation revealed that it applies to gptimer1 and watchdog timer2
as well which may run on 32KHz. This patch fixes the issue for all the
applicable modules.

The BUG has not made it yet to the OMAP errata list and it is applicable to
OMAP1/2/3/4/5. OMAP1/2/3 it is taken care indirectly by autodeps.

By enabling static depedency of wakeup clockdomain with MPU, as soon as MPU
is woken up from lowpower state(idle) or whenever MPU is active, PRCM forces
the OCP clock to be running and allow the counter value to be updated properly
in the OCP clock domain.

The bug is going to fixed in future OMAP versions.

Linus Torvalds b2094ef840 Updates of sound stuff for 3.4-rc1
Here is the first big update chunk of sound stuff for 3.4-rc1.
 
 In the common sound infrastructure, there are a few changes for
 dynamic PCM support (used in ASoC) and a few clean-ups.  Majority of
 changes are found, as usual, in HD-audio and ASoC.
 
 Some highlights of HD-audio changes:
 - All the long-standing static quirk codes for Realtek codec were
 finally removed by fixing and extending the Realtek auto-parser.
 
 - The mute-LED control is standardized over all HD-audio codec
   drivers using the extended vmaster hook.
 
 - The vmaster slave mixer elements are initialized to 0dB as default
   so that the user won't be annoyed by the silent output after
   updates, e.g. due to the additions of new elements.
 
 - Other many fix-ups for the misc HD-audio devices.
 
 In the ASoC side, this is a very active release, including a quite a
 few framework enhancements.  Some highlights:
 
 - Support for widgets not associated with a CODEC, an important part
   of the dynamic PCM framework.
 
 - A library factoring out the common code shared by dmaengine based
   DMA drivers contributed by Lars-Peter Clausen.  This will save a lot
   of code and make it much easier to deploy enhancements to
   dmaengine.
 
 - Support for binary controls, used for providing runtime
   configuration of algorithm coefficients.
 
 - A new DAPM widget type for regulator supplies allowing drivers for
   devices that can power down unused supplies while active to do
   without any per-driver code.
 
 - DAPM widgets for DAIs, initially giving a speed boost for playback
   startup and shutdown and also the basis for CODEC<->CODEC DAI link
   support.
 
 - Support for specifying the number of significant bits on audio
   interfaces, useful for allowing applications to know how much effort
   to put into generating data for a larger sample format.
 
 - Conversion of the FSI driver used on some SH processors to
   DMAEngine.
 
 - Conversion of EP93xx drivers to DMAEngine.
 
 - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
   WM2200.
 
 - Move audmux driver from arc/arm to sound/soc
 
 - McBSP move from arch/ to sound/ and updates
 
 Also, a few small updates and fixes for other drivers like au88x0,
 ymfpci, USB 6fire, USB usx2yaudio are included.

Benoit Cousson 9d4a4199e7 ARM: OMAP2+: board-omap4-*: Do not use anymore TWL6030_IRQ_BASE in board files
With the introduction of dynamically allocated IRQ in the twl6030 driver,
the board files can no longer rely of static IRQ defines like before.

Retrieve the value dynamically allocated from the mmc -> twl6030 init
callback.

Note: The Panda board does not seems to use the card detect IRQ.

Linus Torvalds c207f3a431 Generialize powerpc's irq_host as irq_domain
This branch takes the PowerPC irq_host infrastructure (reverse mapping
 from Linux IRQ numbers to hardware irq numbering), generalizes it,
 renames it to irq_domain, and makes it available to all architectures.
 
 Originally the plan has been to create an all-new irq_domain
 implementation which addresses some of the powerpc shortcomings such
 as not handling 1:1 mappings well, but doing that proved to be far
 more difficult and invasive than generalizing the working code and
 refactoring it in-place.  So, this branch rips out the 'new'
 irq_domain and replaces it with the modified powerpc version (in a
 fully bisectable way of course).  It converts all users over to the
 new API and makes irq_domain selectable on any architecture.
 
 No architecture is forced to enable irq_domain, but the infrastructure
 is required for doing OpenFirmware style irq translations.  It will
 even work on SPARC even though SPARC has it's own mechanism for
 translating irqs at boot time.  MIPS, microblaze, embedded x86 and c6x
 are converted too.
 
 The resulting irq_domain code is probably still too verbose and can be
 optimized more, but that can be done incrementally and is a task for
 follow-on patches.

This is a fix for the regression caused by fixing an earlier

The OMAP McBSP driver stack used to contain two different

the IP, while the other driver was the ASoC DAI driver.
There were global, shared structures, in different places,
the McBSP instances are reffered with id numbers (sometimes
0 based, in other cases 1 based id numbers).

Create one single driver for OMAP McBSP with name: omap-mcbsp.
Convert the old omap-mcbsp driver initially to be a library
for the omap-mcbsp DAI driver. With this change we can get rid
of all global variables, structures.

Remove the omap_mcbsp_init function call which was called from
mach-omap1/2/mcbsp.c to register the platform driver for the just
created platform device in the same function.

commit e4b0b2cbbb (ARM: OMAP2+: gpmc-smsc911x: add required smsc911x
regulators) added regulators which are registered during
gpmc_smsc911x_init().  However, some platforms (OMAP3/Overo) have more
than one instance of the SMSC911x and result in attempting to register
the same regulator more than once which causes a panic().

Fix this by only registering the regulator when the platform_data id
field is zero, indicating its the first instance.

Kevin Hilman c15f1d84bb ARM: OMAP2+: voltage: ensure voltage used is exact voltage from OPP table
When using the SMPS regulators to scale voltages, the regulator
framework may pass a minimum voltage that is not an exact OPP voltage.
For the VC/VP controlled voltage domains, we must ensure that the
voltage requested is the exact voltage from the OPP table.  This is
especially critical when using SR.

To fix, voltdm_scale() uses the target voltage passed to walk through
the OPP voltages until it finds a voltage that is >= one of the OPP
voltages.

sys clocks available.

In the voltage processor, the SPMSUpdateWait is calculated based on
the slew rate and the voltage step (SMPSUpdateWait = slew rate *
Voltage Step). After the voltage processor receives the SMPS_Ack
signal, the Voltage Controller will wait for SMPSUpdateWait clock
cycles for the voltage to settle to the new value. For all
practical purposes, the waittime parameter is the OMAP hardware
translation of what the slew rate on the PMIC is.

As an example, with TPS62361 on OMAP4460,
step_size = 10000
slew_rate = 32000
sys_clk_rate = 38400

Our current computation results in the following:
 = ((step_size / slew_rate) * sys_clk_rate) / 1000
 = ((10000 / 32000) * 38400 / 1000
 = 0

Fix the same using DIV_ROUND_UP as an extra wait clock cycle
is better than lesser clock cycle. For the above example, this
translates to:
 = (10000 * 38400) / (1000 * 32000)
 = 12

Kevin Hilman bb1dbe7cfd ARM: OMAP2+: PM: fix wakeupgen warning when hotplug disabled
When CONFIG_HOTPLUG_CPU=n, there are unused functions in wakeupgen:

arch/arm/mach-omap2/omap-wakeupgen.c:181: warning: 'wakeupgen_irqmask_all' defined but not used

Fix this by moving all the functions only used when CONFIG_HOTPLUG_CPU=y
together and wrapping in an #ifdef.

No functional changes.

Kevin Hilman 1f3b372b3c ARM: OMAP2+: PM: fix section mismatch with omap2_init_processor_devices()
Fix the below warning by making omap2_init_processor_devices() __init.
It is called by an __init function and calls only __init functions, so
it should also be init.

WARNING: arch/arm/mach-omap2/built-in.o(.text+0x183c): Section mismatch in reference from the function omap2_init_processor_devices() to the function .init.text:_init_omap_device()
The function omap2_init_processor_devices() references
the function __init _init_omap_device().
This is often because omap2_init_processor_devices lacks a __init
annotation or the annotation of _init_omap_device is wrong.

If platform data is provided by the caller gpio_pendown is put into
unused static ads7846_config structure and effectively has no effect.
Of course caller can set gpio_pendown field in platform data himself
but it seems natural to do this in ads7846_init to remove duplication.

It turned out wrong OMAP HSUSB port was configured on pandora,
but still managed to work somehow. This was noticed after enabling
in-kernel mux, where USB muxing was causing other devices not to work,
because hsusb1 pins (instead of hsusb2) were wrongly remuxed, which
are used for other things on pandora.

Determine SoC type, i.e. whether GP or HS

Note: cpu_is_34xx() is true for am33xx also. Doing
cpu_is_am33xx() check after cpu_is_34xx() will not
achieve what we want due to the above reason.
Hence cpu_is_am33xx() is done before cpu_is_34xx()
