Resolve this kernel boot message:
omap_hwmod: mcpdm: cannot be enabled for reset (3)
The McPDM on OMAP4 can only receive its functional clock from an
off-chip source. This source is not guaranteed to be present on the
board, and when present, it is controlled by I2C. This would
introduce a board dependency to the early hwmod code which it was not
designed to handle. Also, neither the driver for this off-chip clock
provider nor the I2C code is available early in boot when the hwmod
code is attempting to enable and reset IP blocks. This effectively
makes it impossible to enable and reset this device during hwmod init.
At its core, this patch is a workaround for an OMAP hardware problem.
It should be possible to configure the OMAP to provide any IP block's
functional clock from an on-chip source. (This is true for almost
every IP block on the chip. As far as I know, McPDM is the only
exception.) If the kernel cannot reset and configure IP blocks, it
cannot guarantee a sane SoC state. Relying on an optional off-chip
clock also creates a board dependency which is beyond the scope of the
early hwmod code.
This patch works around the issue by marking the McPDM hwmod record
with the HWMOD_EXT_OPT_MAIN_CLK flag. This prevents the hwmod
code from touching the device early during boot.

Add HWMOD_EXT_OPT_MAIN_CLK flag to indicate that this IP block is
dependent on an off-chip functional clock that is not guaranteed to be
present during initialization. IP blocks marked with this flag are
left in the INITIALIZED state during kernel init.
This is a workaround for a hardware problem. It should be possible to
guarantee that at least one clock source will be present and active
for any IP block's main functional clock. This ensures that the hwmod
code can enable and reset the IP block. Resetting the IP block during
kernel init prevents any bogus bootloader, ROM code, or previous OS
configuration from affecting the kernel. Hopefully a clock
multiplexer can be added on future SoCs.
N.B., at some point in the future, it should be possible to query the
clock framework for this type of information. Then this flag should
no longer be needed.

When waking up from off-mode, some IP blocks are reset automatically by
hardware. For this reason, software must wait until the reset has
completed before attempting to access the IP block.
This patch fixes for example the bug introduced by commit
6c31b2150f ("mmc: omap_hsmmc: remove access
to SYSCONFIG register"), in which the MMC IP block is reset during
off-mode entry, but the code expects the module to be already available
during the execution of context restore.

Since CAM domain (ISS) has no module wake-up dependency
with any other clock domain of the device and the dynamic
dependency from L3_main_2 is always disabled, the domain
needs to be in force wakeup in order to be able to access
it for configure (sysconfig) it or use it.
Also since there is no clock in the domain managed automatically
by the hardware, there is no use to configure automatic
clock domain transition. SW should keep the SW_WKUP domain
transition as long as a module in the domain is required to
be functional.

Using the 'o' memory constraint in inline assembly can result in GCC
generating invalid immediate offsets for memory access instructions with
reduced addressing capabilities (i.e. smaller than 12-bit immediate
offsets):
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54983
As there is no constraint to specify the exact addressing mode we need,
fallback to using 'Q' exclusively for halfword I/O accesses. This may
emit an additional add instruction (using an extra register) in order
to construct the address but it will always be accepted by GAS.

After commit 846a136881 ("ARM: vfp: fix
saving d16-d31 vfp registers on v6+ kernels"), the OMAP 2430SDP board
started crashing during boot with omap2plus_defconfig:
[ 3.875122] mmcblk0: mmc0:e624 SD04G 3.69 GiB
[ 3.915954] mmcblk0: p1
[ 4.086639] Internal error: Oops - undefined instruction: 0 [#1] SMP ARM

[ 4.103149] PC is at vfp_reload_hw+0x1c/0x44
[ 4.107666] LR is at __und_usr_fault_32+0x0/0x8
It turns out that the context save/restore fix unmasked a latent bug
in commit 5aaf254409 ("ARM: 6203/1: Make
VFPv3 usable on ARMv6"). When CONFIG_VFPv3 is set, but the kernel is
booted on a pre-VFPv3 core, the code attempts to save and restore the
d16-d31 VFP registers. These are only present on non-D16 VFPv3+, so
this results in an undefined instruction exception. The code didn't
crash before commit 846a136 because the save and restore code was
only touching d0-d15, present on all VFP.
Fix by implementing a request from Russell King to add a new HWCAP
flag that affirmatively indicates the presence of the d16-d31
registers:
http://marc.info/?l=linux-arm-kernel&m=135013547905283&w=2
and some feedback from Måns to clarify the name of the HWCAP flag.

The scheduler imposes a requirement to sched_clock()
which is to stop the clock during suspend, if we don't
do that any RT thread will be rescheduled in the future
which might cause any sort of problems.
This became an issue on OMAP when we converted omap-i2c.c
to use threaded IRQs, it turned out that depending on how
much time we spent on suspend, the I2C IRQ thread would
end up being rescheduled so far in the future that I2C
transfers would timeout and, because omap_hsmmc depends
on an I2C-connected device to detect if an MMC card is
inserted in the slot, our rootfs would just vanish.
arch/arm/kernel/sched_clock.c already had an optional
implementation (sched_clock_needs_suspend()) which would
handle scheduler's requirement properly, what this patch
does is simply to make that implementation non-optional.
Note that this has the side-effect that printk timings
won't reflect the actual time spent on suspend so other
methods to measure that will have to be used.
This has been tested with beagleboard XM (OMAP3630) and
pandaboard rev A3 (OMAP4430). Suspend to RAM is now working
after this patch.

Devices that use spitz_pm.c will fail to resume
from STR (Suspend To Ram) when the charger plug is inserted
or removed when a device is in STR mode. The culprit is
a misconfigured gpio line - GPIO18. GPIO18 should be configured as a
regular GPIO input but it gets configured as an alternate function
GPIO18_RDY. And then later in postsuspend() it gets configured as
a regular GPIO18 input line.
Fix this by removing the GPIO18_RDY configuration so that GPIO18
only gets configured as a regular gpio input.

Recent changes to PXA PWM support changed the PXA27X PWM device
numbering scheme.
The linux-3.5 PXA PWM driver followed the hardware numbering scheme for
the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear
numbering scheme:
Address Hardware 3.5 pwm_id 3.6-rc1 pwm_id
0x40b00000 PWM0 0 0
0x40b00010 PWM2 2 1
0x40c00000 PWM1 1 2
0x40c00010 PWM3 3 3
The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id
must be changed from 1 to 2.
This patch fixes the backlight PWM device number and at the same time
moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).

As Russell has pointed out, that commit isn't fixing
Software Flow Control at all, and it actually makes
it even more broken.

After commit 24d7b40a60 (ARM: OMAP2+:
PM: MPU DVFS: use generic CPU device for MPU-SS), OPPs are registered
using an existing CPU device, not the omap_device for MPU-SS.
First, fix the board file to use get_cpu_device() as required by the
above commit, otherwise custom OPPs will be added to the wrong device.
Second, the board files OPP init is called from the its init_machine
method, and the generic CPU devices are not yet created when
init_machine is run. Therefore OPP initialization will fail. To fix,
use a device_initcall() for the board file's OPP customization, and
make the device_initcall board-specific by using a machine_is check.

On n900 uart1 pins are not not used for uart, instead they are
used to connect to a cell modem over ssi. Looks like we're
currently missing these signal names for 3430 for some reason,
and only have some of them listed for 3630. Obviously the signals
are there for 3430 if n900 is using them and they are documented
in some TRMs.
Note that these will eventually be replaced by device tree
based pinctrl-single.c driver. But for now these are needed
to verify the SSI pins for devices like Nokia N900.

Fixes the following errors:

[ 2.324432] omap-mcbsp 49024000.mcbsp: invalid rx DMA channel
Which is because we failed to link the sidetone hwmod for McBSP2/3. The
missing sidetone hwmod link will prevent omap_device_alloc() to append the
DMA resources since we - accidentally - end up having the same number of
resources provided from DT (IO/IRQ) as we have in hwmod for the McBSP ports
without the ST resources.

The runtime PM framework assumes that the hardware state of devices
when initialized is disabled. For all omap_devices, we idle/disable
device by default. However, the console uart uses a "no idle" option
during omap_device init in order to allow earlyprintk usage to work
seamlessly during boot.
Because the hardware is left partially enabled after init (whatever
the bootloader settings were), the omap_device should later be fully
initialized (including mux) and the runtime PM framework should be
told that the device is active, and not disabled so that the hardware
state is in sync with runtime PM state.
To fix, after the device has been created/registered, call
omap_device_enable() to finialize init and use pm_runtime_set_active()
to tell the runtime PM core the device is enabled.
Tested on 2420/n810, 3530/Overo, 3530/Beagle, 3730/OveroSTORM,
3730/Beagle-xM, 4460/PandaES.

On OMAP34xx/35xx, and OMAP36xx chips with ES < 1.2, if the PER
powerdomain goes to OSWR or OFF while CORE stays at CSWR or ON, or if,
upon chip wakeup from OSWR or OFF, the CORE powerdomain goes ON before
PER, the UART3/4 FIFOs and McBSP2/3 SIDETONE memories will be
unusable. This is erratum i582 in the OMAP36xx Silicon Errata
document.
This patch implements one of several parts of the workaround: the
addition of the wakeup dependency between the PER and WKUP
clockdomains, such that PER will wake up at the same time CORE_L3
does.
This is not a complete workaround. For it to be complete:
1. the PER powerdomain's next power state must not be set to OSWR or
OFF if the CORE powerdomain's next power state is set to CSWR or
ON;
2. the UART3/4 FIFO and McBSP2/3 SIDETONE loopback tests should be run
if the LASTPOWERSTATEENTERED bits for PER and CORE indicate that
PER went OFF while CORE stayed on. If loopback tests fail, then
those devices will be unusable until PER and CORE can undergo a
transition from ON to OSWR/OFF and back ON.

When booting a secondary CPU, the primary CPU hands two sets of page
tables via the secondary_data struct:
(1) swapper_pg_dir: a normal, cacheable, shared (if SMP) mapping
of the kernel image (i.e. the tables used by init_mm).
(2) idmap_pgd: an uncached mapping of the .idmap.text ELF
section.
The idmap is generally used when enabling and disabling the MMU, which
includes early CPU boot. In this case, the secondary CPU switches to
swapper as soon as it enters C code:
struct mm_struct *mm = &init_mm;
unsigned int cpu = smp_processor_id();
/*
* All kernel threads share the same mm context; grab a
* reference and switch to it.
*/
atomic_inc(&mm->mm_count);
current->active_mm = mm;
cpumask_set_cpu(cpu, mm_cpumask(mm));
cpu_switch_mm(mm->pgd, mm);
This causes a problem on ARMv7, where the identity mapping is treated as
strongly-ordered leading to architecturally UNPREDICTABLE behaviour of
exclusive accesses, such as those used by atomic_inc.
This patch re-orders the secondary_start_kernel function so that we
switch to swapper before performing any exclusive accesses.

Previously the code only acquired spinlock after increasing / decreasing
the usecount value, which is wrong. This leaves a small window where
a task switch may occur between the check of the usecount and the actual
wakeup / sleep of the domain. Fixed by moving the spinlock locking before
the usecount access. Left the usecount as atomic_t if someone wants an
easy access to the parameter through atomic_read.

ARM: shmobile: r8a7779: use __iomem pointers for MMIO
ARM: shmobile: armadillo800eva: __io abuse cleanup
s3c2440_clk_add is a subsys_interface method and calls clkdev_add_table,
which is marked as __init. The modpost script complains about this
because we must not call an __init function from a function in the .text
section, and we cannot reference an __init function from a subsys_interface
pointer.
I have verified that the only code path into s3c2440_clk_add() is
from "int __init s3c2440_init(void)", so s3c2440_clk_add can be marked
__init_refok instead.
Without this patch, building mini2440_defconfig results in:
WARNING: vmlinux.o(.text+0x9848): Section mismatch in reference from the function s3c2440_clk_add() to the function .init.text:clkdev_add_table()
The function s3c2440_clk_add() references
the function __init clkdev_add_table().
This is often because s3c2440_clk_add lacks a __init
annotation or the annotation of clkdev_add_table is wrong.

Commit a5238e360b (spi: s3c64xx: move controller information into driver

spi controller but forgot to set these in the relevant machines.
To fix this introduce a s3c64xx_spi_setname function and populate all
Samsung arches with the correct names. The function resides in a new
header, as the s3c64xx-spi.h contains driver platform data and should
therefore at some later point move out of the Samsung include dir.

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal)
changed the interrupts to allow enabling sparse IRQ, but
accidentally added the omap3 INTC base to the local IRQ.
This causes the following:
twd: can't register interrupt 45 (-22)
twd_local_timer_register failed -22
The right fix is to not add any base, as it is a local
timer. For the OMAP44XX_IRQ_LOCALWDT we had defined earlier
there are no users, so no need to fix that.

Change the type of variable from "unsigned long" to "u64".
This avoids the overflow while clock rate calculating.

Commit 9e3c0066 (ARM: dts: imx6q-arm2: add pinctrl for uart and enet)
defines NANDF_CS pins as gpio in 'hog', assuming these two pins are
always used by usdhc3 in gpio mode as card-detection and
write-protection on ARM2 board. But it's not true. These pins are
shared by usdhc3 and gpmi-nand. We should have the pins functional
for gpmi-nand when usdhc3 is disabled.
Move the pins out of 'hog', so that pins only work in gpio mode as CD
and WP when usdhc3 is enabled, and otherwise they are available for
gpmi-nand.
