Jon Hunter 34cceb7464 ARM: OMAP2+: Fix realtime_counter_init warning in timer.c
In commit fa6d79d (ARM: OMAP: Add initialisation for the real-time
counter), the function realtime_counter_init() was added. However, if
the kernel configuration option CONFIG_SOC_OMAP5 is not selected then
the following compiler warning is observed.

  CC      arch/arm/mach-omap2/timer.o
  arch/arm/mach-omap2/timer.c:489:20: warning: ‘realtime_counter_init’
  defined but not used [-Wunused-function]

Commit fa6d79d also introduced the kernel configuration option
CONFIG_SOC_HAS_REALTIME_COUNTER. If this option is not selected then the
a stub function for realtime_counter_init() is defined.

For non-OMAP5 devices, there is no realtime counter and so
realtime_counter_init() function and stub function are not used for
these devices. Therefore, fix this warning by only allowing the kernel
configuration option CONFIG_SOC_HAS_REALTIME_COUNTER to be enabled for
OMAP5 devices.

Linus Torvalds a11da7df65 ARM: arm-soc: power management and clock changes
This branch contains a largeish set of updates of power management and
 clock setup. The bulk of it is for OMAP/AM33xx platforms, but also a
 few around hotplug/suspend/resume on Exynos.
 
 It includes a split-up of some of the OMAP clock data into separate
 files which adds to the diffstat, but gross delta is fairly reasonable.

 at commit c9d501e5cb are here:
 
 http://www.pwsan.com/omap/testlogs/common_clk_devel_3.8_rebase/20121112192516/
 
 However, cleanup-prcm at c9d501e5 does not include some fixes
 that are needed for a successful test.  With several reverts,
 fixes, and workarounds applied, the following test logs were
 obtained:
 
 http://www.pwsan.com/omap/testlogs/TEST_common_clk_devel_3.8_rebase/20121112192300/
 
 which indicate that the series tests cleanly.
 
 N.B. The common clock data addition patches result in many
 checkpatch warnings of the form "WARNING: static const char *
 array should probably be static const char * const".  However, it
 appears that resolving these would require changes to the CCF
 itself.  So the resolution of these warnings is being postponed
 until that can be coordinated.
 
 These patches result in a ~55KiB increase in runtime kernel memory
 usage when booting omap2plus_defconfig kernels.

Russell King b1b3f49ce4 ARM: config: sort select statements alphanumerically
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.

We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)

The real time counter also called master counter, is a free-running
counter. It produces the count used by the CPU local timer peripherals
in the MPU cluster. The timer counts at a rate of 6.144 MHz.

The ratio registers needs to be configured based on system clock
only onetime. After initialisation, hardware takes care of adjusting
the clock in different low power modes to keep counter rate constant.

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.

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.

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.

- 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.

   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.

Vaibhav Hiremath 1c213ba16e ARM: OMAP2+: am33xx: Make am33xx as a separate class
Initially, we decided to make am33xx family of device to fall
under omap3 class (cpu_is_omap34xx() = true), since it carries
Cortex-A8 core. But while adding complete baseport support
(like, clock, power and hwmod) support, it is observed that,
we are creating more and more problems by treating am33xx device
as omap3 family, as nothing matches between them
(except cortex-A8 mpu).

So,  after long discussion we have came to the conclusion that,
we should not consider am33xx device as omap3 family, instead
create separate class (SOC_AM33XX) under OMAP2PLUS.
This means, for am33xx device, cpu_is_omap34xx() will return false,
and only cpu_is_am33xx() will be true.

commit 164e0cbf60 (ARM: OMAP3/4: consolidate cpuidle Makefile) added
an OMAP-specific dependency from CPU_IDLE to CONFIG_PM.  This causes
some randconfig warnings when CONFIG_PM has unmet dependencies:

warning: (ARCH_OMAP3 && ARCH_OMAP4) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME)

Fix this by making the dependency on CONFIG_PM_RUNTIME (which in turn
will enable CONFIG_PM.)

Daniel Lezcano 164e0cbf60 ARM: OMAP3/4: consolidate cpuidle Makefile
The current Makefile compiles the cpuidle34xx.c and cpuidle44xx.c files
even if the cpuidle option is not set in the kernel.

This patch fixes this by creating a section in the Makefile where these
files are compiled only if the CONFIG_CPU_IDLE option is set.

This modification breaks an implicit dependency between CPU_IDLE and PM as
they belong to the same block in the Makefile. This is fixed in the Kconfig
by selecting explicitely PM is CPU_IDLE is set.

The linux coding style recommend to use no-op functions in the headers
when the subsystem is disabled instead of adding big section in C files.

This patch fix this also.

Tony Lindgren fe57ab0605 ARM: OMAP2: Remove legacy USB FS support
The FS (Full Speed) USB controller is available on 2420 and 2430,
but not being used.

Out of the 2420 based boards only Nokia N8X0 are seeing active
development and they have external HS (High Speed) TUSB controller.
On omap 2430sdp there is MUSB HS controller, so there's no need
to use the legacy USB FS controller.

That leaves only H4 and Apollon boards that could use the FS USB
controller. As both H4 and Apollon boards are old proprietary
development boards, it's unlikely that we have any active
developers working on those boards using the USB.

So remove the FS USB support for omap2 machines. Patches are
welcome if somebody wants to instead fix it all up to the
current standards.

Santosh Shilimkar a78a4cbd41 ARM: OMAP2PLUS: Enable HIGHMEM
HIGMEM support in kernel is quite mature now and we have boards
like ZOOM, PANDA, SDP where 1 GB memories are installed. With
HIGHMEM disabled not all of the 1GB of RAM (only ~700MB) can be
accessed. Hence, enable HIGMEM to make use of the entire memory.

On the boards which doesn't have more than 768 MB memory, all
the memory is directly mapped in "lowmem" and highmem isn't
exercised. Hence, there should be no impact by enabling HIGHMEM
for boards that do not need it.

Tested on OMAP4460 Panda-ES.

If we don't have ARCH_OMAP2, 3 or 4 selected randconfig will always
fail with multiple errors as the CPU and MACHINE are not set.

Fix this by changing arch/arm/Makefile to build mach-omap2 based on
ARCH_OMAP2PLUS. And let's introduce SOC_OMAP and SOC_OMAP_NOOP that
allow randconfig to generate buildable .config files.

Note that we can also remove few uncecssary ARCH_OMAP2PLUS lines
as they are all within if ARCH_OMAP2PLUS block.

Will Deacon a092f2b153 ARM: 7291/1: cache: assume 64-byte L1 cachelines for ARMv7 CPUs
To ensure correct alignment of cacheline-aligned data, the maximum
cacheline size needs to be known at compile time.

Since Cortex-A8 and Cortex-A15 have 64-byte cachelines (and it is likely
that there will be future ARMv7 implementations with the same line size)
then it makes sense to assume that CPU_V7 implies a 64-byte L1 cacheline
size. For CPUs with smaller caches, this will result in some harmless
padding but will help with single zImage work and avoid hitting subtle
bugs with misaligned data structures.
