3ead4679e5 ARM: OMAP: Remove CONFIG_OMAP_MCBSP references
The McBSP driver stack has been moved to ASoC. The CONFIG_OMAP_MCBSP will
be removed since the CONFIG_SND_OMAP_SOC_MCBSP will trigger to build the
McBSP (audio) drivers.

40c0764b18 ARM: OMAP2+: McBSP: Correct CLKR/FSR clock source mux configuration
On OMAP2/3 McBSP1 port has 6 pin setup, while on OMAP4 the port is McBSP4.
Implement the CLKR/FSR clock mux selection for OMAP4, and make sure that
we add the correct callback for the correct port across supported OMAP
versions.

45656b44f6 ASoC: omap-mcbsp: Create a single driver for McBSP
The OMAP McBSP driver stack used to contain two different
drivers. One of them was used as kind low-level access to
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.

Further cleanup is coming...

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.

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.

3223d007a3 ARM: OMAP3+: PM: VP: fix integer truncation error
commit 2f34ce81b8
(OMAP3: PM: Adding voltage driver support.)
introduced runtime computation of waittime to handle all potential
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

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.

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

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.

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()

The platform_suspend_ops can be shared across OMAP2, 3, and 4, along
with all of the functions referenced in that structure.  This patch
shares them.  It also removes the suspend_state file-scoped variable
in the OMAP2 and 3 PM code; it does not appear to be actually needed
by anything.

e68e8093ed ARM: OMAP2+: PM: clean up omap_set_pwrdm_state()
Clean up a few different parts of omap_set_pwrdm_state():

- Remove a superfluous call to pwrdm_state_switch().  Not needed
  unless LOWPOWERSTATECHANGE is used, because the state switch code is
  called by either clkdm_sleep() or clkdm_allow_idle().

- Add code to wait for the power state transition in the OMAP4+ low
  power state change.  This is speculative, so I would particularly
  appreciate feedback on this part.

- Remove a superfluous call to pwrdm_read_pwrst().

- Update variable names to be more meaningful (hopefully) and precise.

- Fix an error path bug that would not place the clockdomain back into
  hardware-supervised idle or sleep mode if the power state could not
  be programmed.

The documentation for this function still needs major improvements;
that's left for a later patch.
