Santosh Shilimkar 0ae28542a8 ARM: OMAP4: Don't compile cm2xxx_3xxx.c for OMAP4 only builds.
Since OMAP4 code base now makes use of OMAP4 specific PRCM functions,
cm2xxx_3xxx.c need not be compiled for OMAP4 only builds.

Paul Walmsley 6ba5a69ee9 ARM: OMAP2+: clockdomains: make {prm,cm}_clkdm common
The PRM and CM implicit clockdomains will soon be used by OMAP44xx.
So, make them common to OMAP2+ and modify the OMAP4 clockdomains code
so use of these clockdomains doesn't crash the system.

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.

During kernel init, we reset all IP blocks on the OMAP that we can,
even if there is no driver compiled for that IP block.  Unlike most IP
blocks, the I2C block requires some extra programming for this to
work.  This reset code is incorrectly omitted when the I2C driver is
deselected.  In this circumstance, the build breaks.  Fix by compiling
the I2C reset code unconditionally.

Tero Kristo 0a84a91c37 ARM: OMAP: PRCM: add support for chain interrupt handler
Introduce a chained interrupt handler mechanism for the PRCM
interrupt, so that individual PRCM event can cleanly be handled by
handlers in separate drivers. We do this by introducing PRCM event
names, which are then matched to the particular PRCM interrupt bit
depending on the specific OMAP SoC being used.

PRCM interrupts have two priority levels, high or normal. High priority
is needed for IO event handling, so that we can be sure that IO events
are processed before other events. This reduces latency for IO event
customers and also prevents incorrect ack sequence on OMAP3.

Note that existing TI8168 EVM file (board-ti8168evm.c) is updated with machine
info for TI8148 EVM.

Santosh Shilimkar 9827266097 ARM: OMAP4: PM: Add CPUidle support
Add OMAP4 CPUIDLE support. CPU1 is left with defualt idle and
the low power state for it is managed via cpu-hotplug.

This patch adds MPUSS low power states in cpuidle.

	C1 - CPU0 ON + CPU1 ON + MPU ON
	C2 - CPU0 OFF + CPU1 OFF + MPU CSWR
	C3 - CPU0 OFF + CPU1 OFF + MPU OSWR

OMAP4460 onwards, MPUSS power domain doesn't support OFF state any more
anymore just like CORE power domain. The deepest state supported is OSWr.
Ofcourse when MPUSS and CORE PD transitions to OSWR along with device
off mode, even the memory contemts are lost which is as good as
the PD off state.

On OMAP4 because of hardware constraints, no low power states are
targeted when both CPUs are online and in SMP mode. The low power
states are attempted only when secondary CPU gets offline to OFF
through hotplug infrastructure.

Thanks to Nicole Chalhoub <n-chalhoub@ti.com> for doing exhaustive
C-state latency profiling.

Santosh Shilimkar fcf6efa3ff ARM: OMAP4: PM: Add WakeupGen module as OMAP gic_arch_extn
OMAP WakeupGen is the interrupt controller extension used along
with ARM GIC to wake the CPU out from low power states on
external interrupts.

The WakeupGen unit is responsible for generating the wakeup event
from the incoming interrupts and enable bits. It is implemented
in the MPU always ON power domain. During normal operation,
WakeupGen delivers the external interrupts directly to the GIC.

WakeupGen specification has one restriction as per Veyron version 1.6.
It is SW responsibility to program interrupt enabling/disabling
coherently in the GIC and in the WakeupGen enable registers. That is, a
given interrupt for a given CPU is either enable at both GIC and WakeupGen,
or disable at both, but no mix. That's the reason the WakeupGen is
implemented as an extension of GIC.

Tomi Valkeinen 13662dc5b1 ARM: OMAP: HWMOD: Unify DSS resets for OMAPs
This patch adds a custom DSS reset function used on OMAPs from OMAP2
forward.

The function doesn't actually do a reset, it only waits for the reset to
complete. The reason for this is that on OMAP4 there is no possibility
to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets
all the other DSS modules also, thus breaking the HWMOD model where
every DSS module is handled independently.

This fixes the problem with DSS reset on OMAP4, caused by the fact that
because there's no SW reset for dss_core on OMAP4, the HWMOD framework
doesn't try to reset dss_core and thus the DSS clocks were never enabled
at the same time. This causes causes the HWMOD reset to fail for
dss_dispc and dss_rfbi.

The common reset function will also allow us to fix another problem in
the future: before doing a reset we need to disable DSS outputs, which
are in some cases enabled by the bootloader, as otherwise DSS HW seems
to get more or less stuck, requiring a power reset to recover.

In commit 7538e3db6e (PM: add support

Rather than using the platform_bus dev_pm_ops overrides

implementation over to using device power domains.

Since OMAP is the only user of platform_bus_set_pm_ops(), that
interface can be removed (and will be in a forthcoming patch.)

Paul Walmsley c0718df4d6 OMAP2+: voltage: reorganize, split code from data
This is a first pass at reorganizing mach-omap2/voltage.c:

- Separate almost all of the data from the code of mach-omap2/voltage.c.
  The code remains in mach-omap2/voltage.c.  The data goes into one
  of several places, depending on what type of data it is:

  - Silicon process/validation data: mach-omap2/opp*_data.c
  - VC (Voltage Controller) data: mach-omap2/vc*_data.c
  - VP (Voltage Processor) data: mach-omap2/vp*_data.c
  - Voltage domain data: mach-omap2/voltagedomains*_data.c

  The ultimate goal is for all this data to be autogenerated, the same
  way we autogenerate the rest of our data.

- Separate VC and VP common data from VDD-specific VC and VP data.

- Separate common voltage.c code from SoC-specific code; reuse common code.

- Reorganize structures to avoid unnecessary memory loss due to unpacked
  fields.

There is much left to be done.  VC code and VP code should be separated out
into vc*.c and vp*.c files.  Many fields in the existing structures are
superfluous, and should be removed.  Some code in voltage.c seems to be
duplicated; that code should be moved into functions of its own.  Proper
voltage domain code should be created, as was done with the powerdomain

Thanks to Shweta Gulati <shweta.gulati@ti.com> for comments.  Thanks
to Rajendra Nayak <rnayak@ti.com> for finding and fixing some bugs
that prevented OMAP4 from booting:

between patches.  Thanks also to Kevin Hilman <khilman@ti.com> for
finding and fixing a compile problem when !CONFIG_PM:
