Arnd Bergmann c7a9b09b1a ARM: omap: allow building omap44xx without SMP
The new omap4 cpuidle implementation currently requires
ARCH_NEEDS_CPU_IDLE_COUPLED, which only works on SMP.

This patch makes it possible to build a non-SMP kernel
for that platform. This is not normally desired for
end-users but can be useful for testing.

Without this patch, building rand-0y2jSKT results in:

drivers/cpuidle/coupled.c: In function 'cpuidle_coupled_poke':
drivers/cpuidle/coupled.c:317:3: error: implicit declaration of function '__smp_call_function_single' [-Werror=implicit-function-declaration]

It's not clear if this patch is the best solution for
the problem at hand. I have made sure that we can now
build the kernel in all configurations, but that does
not mean it will actually work on an OMAP44xx.

Rajendra Nayak 196449de0c ARM: OMAP4: Register the OPP table only for 4430 device
The 4430 OPP table was being registered for all other OMAP4 variants
too, like 4460 and 4470 causing issues with cpufreq driver
enabled. 4460 and 4470 devices have different OPPs as compared to
4430, and they should be populated seperately. As long as that
happens, let the OPP table registeration happen only on 4430 device.

Santosh Shilimkar 5b6e3eb576 ARM: OMAP4: sleep: Save the complete used register stack frame
OMAP4 sleep entry code even though itself don't use many CPU registers
makes call to the v7_flush_dcache_all() which uses them. Since
v7_flush_dcache_all() doesn't make use of stack, the caller must take
care of the stack frame. Otherwise it will lead to corrupted stack frame.

Fix it by saving used registers.

Kevin Hilman e0e29fd74c Revert "ARM: OMAP3: PM: call pre/post transition per powerdomain"
This reverts commit 58f0829b71.

Converstion to per-pwrdm per/post transition calls was a bit
premature.  Only tracking MPU, PER & CORE in the idle path means we
lose the accounting for all the other powerdomains which may also
transition in idle.  On OMAP3, due to autodeps, several powerdomains
transition along with MPU (e.g. DSS, USBHOST), and the accounting for
these was lost with this patch.  Since the accounting includes the
context loss counters, drivers for devices in those power domains
would never notice context lost, so would likely hang after any
off-mode transitions.

This patch should be revisited when the upcoming clkdm/pwrmdm/voltdm
use-counting seires is merged since then we can properly do accounting
without relying on a call in the idle path.

In addition, the original patch had another bug because the PER
powerdomain accounting was not updated until after the GPIO resume
hook is called.  Since gpio_resume_after_idle() checks the context
loss count (which is not yet updated) it would not properly restore
context, leaving the GPIO banks in an undefined state.

Kevin Hilman 265a2bc842 ARM: OMAP3: TWL4030: ensure sys_nirq1 is mux'd and wakeup enabled
The SYS_NIRQ1 pin is the interupt line for the PMIC part of the TWL6030
and interrupts from the PMIC are needed as wakeup sources.

Ensure this pin is mux'd as input and has wakeup enabled so PMIC
interupts (e.g. RTC) can be used as wakeup sources.

Tested on 3430/n900, OMAP3530/Overo Fire, 3730/Overo FireSTORM,

Santosh Shilimkar acb11fe80a OMAP2+: Fix random config build break with !ARM_CPU_SUSPEND
The random config builds with PM and !ARM_CPU_SUSPEND breaks with below
error on omap2plus_defconfig.

arch/arm/mach-omap2/sleep44xx.S:323: undefined reference to `cpu_resume'
arch/arm/mach-omap2/omap-mpuss-lowpower.c:278: undefined reference to `cpu_suspend'

This is because recently merged OMAP5 platform shares the common files
with OMAP4 but doesn't select ARM_CPU_SUSPEND. Without the ARM_CPU_SUSPEND
the sleep code is meaningless.

Fix the same by adding ARM_CPU_SUSPEND for OMAP5. The suggestion came from
Russell King in an off-list discussion.

Javier Martinez Canillas a71eb61c9d ARM: OMAP3: igep0020: set GPIO mode for mux mcspi1_cs2 pin
According to the IGEPv2 Rev.C data-sheet the LAN9221i pin 14 (IRQ) is
connected to the OMAP3730 mcspi1_cs2 pin. Since this omap mux pin acts
as an IRQ line, it has to be configured as an input GPIO.

IGEPv2 platform code sets the smsc911x_cfg->gpio_irq to GPIO 176 but
since the mux pin default mode is MODE7 (safe_mode) the driver fails
when trying to register the IRQ with the following error message:

Igor Grinberg c31cc1b764 Revert "ARM: OMAP3530evm: set pendown_state and debounce time for ads7846"
1) The above commit introduced a common ->get_pendown_state() function
into the generic code, but that function was board-specific for the
OMAP3EVM and thus broke most other boards using this code.

2) The above commit was mis-merged introducing another bug which
prevents the ads7846 driver probe function to succeed.
The omap_ads7846_init() function frees the pendown GPIO in case there is
no ->get_pendown_state() function set by the caller (board specific
code), so it can be requested later by the ads7846 driver.
The above commit add a common ->get_pendown_state() function without
removing the gpio_free() call and thus once the ads7846 driver tries
to use the pendown GPIO, it crashes as the pendown GPIO has not been
requested.

3) The above commit introduces NO new functionality as
get_pendown_state() function is already implemented in a suitable way by
the ads7846 driver and the debounce time handling has already been
fixed by commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code).

This reverts commit 16aced80f6.

Conflicts:
	arch/arm/mach-omap2/common-board-devices.c

Solved by taking the working version prior to the above commit.

Linus Torvalds bfdf85dfce ARM: arm-soc: cpuidle enablement for OMAP
Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but
 didn't go in because the pull request ended up rejected. So it just got
 merged, and we got this staged branch that enables the coupled cpuidle
 code on OMAP.
 
 With a stable git workflow from the other maintainer we could have staged
 this earlier, but that wasn't the case so we have had to merge it late.
 
 The alternative is to hold it off until 3.7 but given that the code is
 well-isolated to OMAP and they are eager to see it go in, I didn't push
 back hard in that direction.

Linus Torvalds a6dc77254b Merge branch 'dmaengine' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM DMA engine updates from Russell King:
 "This looks scary at first glance, but what it is is:
   - a rework of the sa11x0 DMA engine driver merged during the previous
     cycle, to extract a common set of helper functions for DMA engine
     implementations.
   - conversion of amba-pl08x.c to use these helper functions.
   - addition of OMAP DMA engine driver (using these helper functions),
     and conversion of some of the OMAP DMA users to use DMA engine.

  Nothing in the helper functions is ARM specific, so I hope that other
  implementations can consolidate some of their code by making use of
  these helpers.

  This has been sitting in linux-next most of the merge cycle, and has
  been tested by several OMAP folk.  I've tested it on sa11x0 platforms,
  and given it my best shot on my broken platforms which have the
  amba-pl08x controller.

  The last point is the addition to feature-removal-schedule.txt, which
  will have a merge conflict.  Between myself and TI, we're planning to
  remove the old TI DMA implementation next year."

Russell King 8a23fa1b95 ARM: omap: remove mmc platform data dma_mask and initialization
DMAengine uses the DMA engine device structure when mapping/unmapping
memory for DMA, so the MMC devices do not need their DMA masks
initialized (this reflects hardware: the MMC device is not the device
doing DMA.)

Santosh Shilimkar b93d70aeb8 ARM: OMAP4: CPUidle: Open broadcast clock-event device.
OMAP4 idle driver uses CLOCK_EVT_NOTIFY_BROADCAST_[ENTER/EXIT]
for broadcast clock events. But _ENTER/_EXIT doesn't really open
broadcast clock events and to explicitly setup the broadcast device,
CLOCK_EVT_NOTIFY_BROADCAST_ON should be used.

Add the missing CLOCK_EVT_NOTIFY_BROADCAST_ON clockevent notifications.
This will setup the broadcast timer in either periodic/oneshot modes
correctly. Recent clockevent infrastructure change 77b0d60 {leave the
broadcast device in shutdown mode when not needed} exposed this bug
leading to boot hangs in oneshot mode. Prior to this, periodic broadcast
mode was also broken. This change fixes both the periodic/oneshot broadcast
modes.

Kevin Hilman 5b4d5bcc68 ARM: OMAP4: CPUidle: add synchronization for coupled idle states
With coupled idle states, a failure for any CPU to hit a low power
state must be coordinated such that all CPUs abort.

On OMAP4, when entering a coupled state, CPU0 has to wait for CPU1 to
enter its low power state before it can enter its low power state.

This is implemented by letting CPU0 wait for the CPU1 powerdomain to
hit off.  However, there are conditions where CPU1 might abort/fail
and not hit off while CPU0 is waiting for it.  For example, a CPU1
wakeup or a failed attempt to hit off due to hardware conditions.

To avoid the deadlock where CPU0 would continually wait for CPU1 to
hit off-mode, this patch adds a flag to signal when each CPU has come
out of its low-power state.  CPU0 then checks whether CPU1 has hit off
*or* has already completed its attempt to hit off.  If the latter,
CPU0 must abort its attempt to hit a low-power state so the coupled
state enter method can return.

In addition, cpuidle_coupled_parallel_barrier() is used to ensure the
clearing of the 'done' flag is synchronized on all CPUs.

Santosh Shilimkar dd3ad97c56 ARM: OMAP4: CPUidle: Use coupled cpuidle states to implement SMP cpuidle.
OMAP4 CPUDILE driver is converted mainly based on notes from the
coupled cpuidle patch series.

The changes include :
- Register both CPUs and C-states to cpuidle driver.
- Set struct cpuidle_device.coupled_cpus
- Set struct cpuidle_device.safe_state to non coupled state.
- Set CPUIDLE_FLAG_COUPLED in struct cpuidle_state.flags for each
  state that affects multiple cpus.
- Separate ->enter hooks for coupled & simple idle.
- CPU0 wait loop for CPU1 power transition.
- CPU1 wakeup mechanism for the idle exit.
- Enabling ARCH_NEEDS_CPU_IDLE_COUPLED for OMAP4.

For coupled cpuidle to work when both cpus are active, it needs a global timer
that can handle events for both cpus.  This timer is used as the broadcast
clock-event when the per-cpu timer hardware stop in low power states.
Set the cpumask of clockevent_gpt to all cpus, set the rating correctly, and
set the irq to allow the clockevent core to determine the affinity of the
timer.

Linus Torvalds f01b9b73f5 arm-soc: new SoC support
This adds support for three new SoC types:
 * The mvebu platform includes Marvell's Armada XP and Armada 370 chips,
   made by the mvebu business unit inside of Marvell. Since the same
   group also made the older but similar platforms we call "orion5x",
   "kirkwood", "mv78xx0" and "dove", we plan to move all of them into
   the mach-mvebu directory in the future.
 * socfpga is Altera's platform based on Cortex-A9 cores and a lot of
   FPGA space. This is similar to the Xilinx zynq platform we already
   support. The code is particularly clean, which is helped by the fact
   that the hardware doesn't do much besides the parts that are
   expected to get added in the FPGA.
 * The OMAP subarchitecture gains support for the latest generation,
   the OMAP5 based on the new Cortex-A15 core. Support is rather
   rudimentary for now, but will be extended in the future.

Merge tag 'newsoc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull support for three new arm SoC types from Arnd Bergmann:

 - The mvebu platform includes Marvell's Armada XP and Armada 370 chips,
   made by the mvebu business unit inside of Marvell.  Since the same
   group also made the older but similar platforms we call "orion5x",
   "kirkwood", "mv78xx0" and "dove", we plan to move all of them into
   the mach-mvebu directory in the future.

 - socfpga is Altera's platform based on Cortex-A9 cores and a lot of
   FPGA space.  This is similar to the Xilinx zynq platform we already
   support.  The code is particularly clean, which is helped by the fact
   that the hardware doesn't do much besides the parts that are expected
   to get added in the FPGA.

 - The OMAP subarchitecture gains support for the latest generation, the
   OMAP5 based on the new Cortex-A15 core.  Support is rather
   rudimentary for now, but will be extended in the future.

Linus Torvalds 4f2d658b2f arm-soc: device tree description updates
This branch contains two kinds of updates: Some platforms in the process
 of getting converted to device tree based booting, and the platform
 specific patches necessary for that are included here. Other platforms
 are already converted, so we just need to update the actual device
 tree source files and the binding documents to add support for new board
 and new drivers.
 In the future we will probably separate those into two branches, and
 in the long run, the plan is to move the device tree source files out
 of the kernel repository, but that has to wait until we have completed
 a much larger portion of the binding documents.
