fcbcea93ab omap3: zoom 2/3: Change debugboard serial port id
This is now changed to PLAT8250_DEV_PLATFORM (= 0), because
it's the only port that's going to be initialized in
Zoom 2/3 boards.

So, it doesn't make sense to keep the hardcoded 3 value anymore.

The event selection mask for ARMv7 cores [ARMV7_EVTSEL_MASK]
is incorrectly set to 0x7f. This means that the top bit of an
event ID is ignored, so counting branch misses (id=0x10) and
ISBs (id=0x90) give the same results.

This patch sets the event selection mask to the correct value
of 0xff.

ddee87f208 ARM: 5959/1: ARM: perf-events: request PMU interrupts with IRQF_NOBALANCING
If IRQ balancing is used on a multicore ARM system, PMU interrupt
lines may be relocated onto CPUs other than the one causing the
counter overflow. This can result in misattribution of events to
the wrong core and, in the case that the CPU handling the interrupt
has not experience counter overflow, the interrupt can be disabled
because the handler returns IRQ_NONE.

This patch adds the IRQF_NOBALANCING flag to the request_irq call
in perf_events.c.

Commit 5de813b6 (ARM: Eliminate decompressor -Dstatic= PIC hack) among
other things changed the declared type of the error() function to an
extern, conflicting with the forward declartion in the Samsung
plat/uncompress.h which appears to have been relying on the static
being defined away, causing build failures since error() ends up with
a GOT relocation but the linker script discards all GOT relocated
data and functions:

/home/broonie/git/linux-2.6/arch/arm/boot/compressed/../../../../lib/decompress_
+inflate.c:68: undefined reference to `error'

and so on. Fix this by moving the declaration into uncompress/misc.c
where it is shared with the rest of the code, correcting the definition
as we go.

440e6ca79a arm: use generic ptrace_resume code
Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT,
PTRACE_KILL and PTRACE_SINGLESTEP.  This implies defining
arch_has_single_step in <asm/ptrace.h> and implementing the
user_enable_single_step and user_disable_single_step functions, which also
causes the breakpoint information to be cleared on fork, which could be
considered a bug fix.

Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which
it previously wasn't and the single stepping disable only happens if the
tracee process isn't a zombie yet, which is consistent with all
architectures using the modern ptrace code.

baed7fc9b5 Add generic sys_ipc wrapper
Add a generic implementation of the ipc demultiplexer syscall.  Except for
s390 and sparc64 all implementations of the sys_ipc are nearly identical.

There are slight differences in the types of the parameters, where mips
and powerpc as the only 64-bit architectures with sys_ipc use unsigned
long for the "third" argument as it gets casted to a pointer later, while
it traditionally is an "int" like most other paramters.  frv goes even
further and uses unsigned long for all parameters execept for "ptr" which
is a pointer type everywhere.  The change from int to unsigned long for
"third" and back to "int" for the others on frv should be fine due to the
in-register calling conventions for syscalls (we already had a similar
issue with the generic sys_ptrace), but I'd prefer to have the arch
maintainers looks over this in details.

Except for that h8300, m68k and m68knommu lack an impplementation of the
semtimedop sub call which this patch adds, and various architectures have
gets used - at least on i386 it seems superflous as the compat code on
x86-64 and ia64 doesn't even bother to implement it.

0841cb8268 omap: McBSP: Drop unnecessary status/error bit clearing on reg_cacheretrieved register values
The MsBSP register cache will never have any error/status flags set, since
these flags are never written to the reg_cache. So it is kind of not
necessary to clear these flags, which are actually always 0.

In other words, clearing the status/error flags are not necessary, since the
reg_cache will never got these bits set. We can just write back the
register content from the cache as it is when clearing an error condition.

Tested on Amstrad Delta.

aa4b1f6e83 OMAP4: fix temporary hacks that break multi-omap PM
When building for multi-omap, and OMAP4 is enabled, CONFIG_ARCH_OMAP4
will be true and prevent included code from building/running for
OMAP2/3 as well.

This problem exists in io.c where some hwmod/PM/SDRC init code is
prevented from running even on OMAP2/3 when OMAP4 is included in a
multi-OMAP build.

A quick glance suggests that this #ifndef is no longer needed in most
of the cases.  In the remaining cases, the function is wrapped with
"if (cpu_is_omap24xx() || cpu_is_omap34xx())" which will be optimized
out for OMAP4-only builds.

Note that this is only a short-term fix.  Longer-term, OMAP4
needs to create init functions for SDRC and hwmod late-init.

54c44fb7df OMAP2: cpu_is_omap2*: fix compile-time removal of unused code
Currently if omap2420 is defined but not omap2430, cpu_is_omap2430()
is still defined as a macro, instead of #define'd to zero.  This
results in conditional cpu_is_omap2430() code still being compiled,
and leads to possible compile/link errors.  In particular for hwmod
init.

To fix, add extra #ifdefs to CPU check macros to ensure that the
is_omap* macros are zero for each OMAP2 if they are not configured
into the kernel.

29b9a218d0 omap: pass the reboot command to the boot loader
This patch follows the commit be093beb60
by Russell King:

  OMAP wishes to pass state to the boot loader upon reboot in order
  to instruct it whether to wait for USB-based reflashing or not.
  There is already a facility to do this via the reboot() syscall,
  except we ignore the string passed to machine_restart().

The patch adds the missing parameter to omap1_arch_reset() and
omap_prcm_arch_reset(), and modifies the latter to pass the reboot
command parameter to the boot loader instead of reboot mode (which is
for kernel internal use only and cannot be modified by the userspace).

Recent DMA API changes broke compile for tusb6010. While
testing the fixes for tusb6010, I had to update the n8x0
defconfig quite a bit. Might as well merge it while at it
to make it more usable as we're using this to test the
multi-omap booting between V6 and V7 ARMs.

Also, anybody using n8x0 with a current kernel will most
likely want to mount root on the MMC instead of the onenand
to keep the Maemo install intact.

Enable I2C, REGULATOR, MMC, MFD, PM, and USB. Also change the root
to /dev/mmcblk0p2 instead of the onenand.

the early_param() call in board-omap3touchbook.c expands to:

static const char __setup_str_early_touchbook_revision[]
	__section(.init.rodata) _aligned(1) = tbr;
[...]

and we have a non-const variable being added to the
same section:

static struct ehci_hcd_omap_platform_data ehci_pdata
__section(.init.rodata);

because of that, gcc generates a section type conflict
which can (and actually should) be avoided by marking
const every variable marked with __initconst.

This patch fixes that for the ehci_hdc_omap_platform_data.

91a99dfc6b platform-drivers: move probe to .devinit.text in arch/arm
A pointer to a probe callback is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

f1acb878b6 iop-adma: redundant/wrong tests in iop_*_count()?
When we reach the loop, len is at least 1, we only stay in the loop when
len is at least MAX_BYTE_COUNT + 1, MAX_BYTE_COUNT is subtracted in each
iteration. So when we leave the loop, or didn't take it, len is at least 1.
Testing whether len is non-zero appears redundant.

6b727c68ea pxa_camera: remove init() callback
pxa_camera init() callback is sometimes abused to setup MFP for PXA CIF, or
even to request GPIOs to be used by the camera *sensor*. These initializations
can be performed statically in machine init functions.

The current semantics for this init() callback is ambiguous anyways, it is
invoked in pxa_camera_activate(), hence at device node open, but its users use
it like a generic initialization to be done at module init time (configure
MFP, request GPIOs for *sensor* control).

98e12b5a6e ARM: Fix decompressor's kernel size estimation for ROM=y
Commit 2552fc2 changed the way the decompressor decides if it is safe
to decompress the kernel directly to its final location.  Unfortunately,
it took the top of the compressed data as being the stack pointer,
which it is for ROM=n cases.  However, for ROM=y, the stack pointer
is not relevant, and results in the wrong answer.

Fix this by explicitly storing the end of the biggybacked data in the
decompressor, and use that to calculate the compressed image size.

5de813b6cd ARM: Eliminate decompressor -Dstatic= PIC hack
We used to build decompressors with -Dstatic= to avoid any local data
being generated.  The problem is that local data generates GOTOFF
relocations, which means we can't relocate the data relative to the
text segment.

Global data, on the other hand, goes through the GOT, and can be
relocated anywhere.

Unfortunately, with the new decompressors, this presents a problem
since they declare static data within functions, and this leads to
stack overflow.

Fix this by separating out the decompressor code into a separate file,
and removing 'static' from BSS data in misc.c.

Also, discard the .data section - this means that should we end up
with read/write initialized data, the decompressor will fail to link
and the problem will be obvious.

7c43d54728 OMAP4: clock: Add dummy clock nodes for interface clocks
On OMAP4 platform the iclk control is completly under hardware control
and no software control is available.

This difference w.r.t previous OMAP's needs all the common driver
accross OMAP's , cpu_is_xxxx() checks. To avoid poulluting the

30962d9d0c OMAP2+ clock: revise omap2_clk_{disable,enable}()
Simplify the code in the omap2_clk_disable() and omap2_clk_enable()
functions, reducing levels of indentation.  This makes the code easier
to read.  Add some additional debugging pr_debug()s here also to help
others understand what is going on.

Revise the omap2_clk_disable() logic so that it now attempts to
disable the clock's clockdomain before recursing up the clock tree.
Simultaneously, ensure that omap2_clk_enable() is called on parent
clocks first, before enabling the clockdomain.  This ensures that a
parent clock's clockdomain is enabled before the child clock's
clockdomain.  These sequences should be the inverse of each other.

Revise the omap2_clk_enable() logic so that it now cleans up after
itself upon encountering an error.  Previously, an error enabling a
parent clock could have resulted in inconsistent usecounts on the
enclosing clockdomain.

Remove the trivial _omap2_clk_disable() and _omap2_clk_enable() static
functions, and replace it with the clkops calls that they were
executing.

For all this to work, the clockdomain omap2_clkdm_clk_enable() and
omap2_clkdm_clk_disable() code must not return an error on clockdomains
without CLKSTCTRL registers; so modify those functions to simply return 0
in that case.

While here, add some basic kerneldoc documentation on both functions,
and get rid of some old non-CodingStyle-compliant comments that have
existed since the dawn of time (at least, the OMAP clock framework's
time).

43b40992ce OMAP hwmod: add hwmod class support
Add support for categorizing and iterating over hardware IP blocks by

50ebdac2ec OMAP hwmod: convert hwmod to use hardware clock names rather than clkdev dev+con
The OMAP hwmod core code is intended to use SoC IP block description
structures that are autogenerated from TI's OMAP hardware database.
Currently the hwmod code uses clkdev device + connection addressing to
identify clocks.  This causes problems in the hwmod autogeneration
process, since the TI hardware database doesn't use platform_device or
clkdev addressing; it uses a single clock signal name string, which
tends to bear some resemblance to what is used in the OMAP TRMs.  This
patch converts the hwmod code and existing data to use omap_clk_get_by_name(),
introduced in the previous patch.

74be842743 OMAP clock: add omap_clk_get_by_name() for use by OMAP hwmod core code
The OMAP hwmod core code is intended to use SoC IP block description
structures that are autogenerated from TI's OMAP hardware database.
Currently the hwmod code uses clkdev device + connection addressing to
identify clocks.  This causes problems in the hwmod autogeneration
process, since the TI hardware database doesn't use platform_device or
clkdev addressing; it uses a single clock signal name string, which
tends to bear some resemblance to what is used in the OMAP TRMs.  This
patch adds a non-exported function to the OMAP clock code,
omap_clk_get_by_name().  A subsequent patch will convert the hwmod
code to use this function.

This function is for use only by core code, and practically, no other
code outside the hwmod code should need it.  Device driver code in the
kernel must not use this function, which is why it is not exported.
Drivers should use the appropriate clock alias provided by the clkdev
data structures, so driver code can be completely SoC-independent.

51c1954162 OMAP clock: drop RATE_FIXED clock flag
The RATE_FIXED clock flag is pointless.  In the OMAP1 clock code, it
simply causes the omap1_clk_round_rate() function to return the
current rate of the clock.  omap1_clk_round_rate(), however, should
never be called for a fixed-rate clock, since none of these clocks
have a .round_rate function pointer set in their struct clk records.
Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes
the clock code to emit a warning if the OMAP clock maintainer was
foolish enough to add a .round_rate function pointer to a fixed-rate
clock.  "Doctor, it hurts when I pretend that a fixed-rate clock is
rate-changeable."  "Then don't pretend that a fixed-rate clock is
rate-changeable."  It has no functional value.  This patch drops the
RATE_FIXED clock flag, removing it from all clocks that are so marked.

of the virt_prcm_set OPP virtual clock.  On 24xx, these clocks all
need to be changed as part of a group to keep the clock tree
functional - hence the need for the VALID_CONFIG bit, which is not
present on later OMAPs.  These clocks should not be rate-changed
independently.  So prevent these clocks from being changed
independently by dropping their .round_rate and .set_rate function
pointers.  It then turns out that the DELAYED_APP clock flag is no
longer useful, so drop it and the associated code and renumber the

81b34fbecb OMAP2 clock: split OMAP2420, OMAP2430 clock data into their own files
In preparation for multi-OMAP2 kernels, split
mach-omap2/clock2xxx_data.c into mach-omap2/clock2420_data.c and
mach-omap2/clock2430_data.c.  2430 uses a different device space
physical memory layout than past or future OMAPs, and we use a
different virtual memory layout as well, which causes trouble for
architecture-level code/data that tries to support both.  We tried
using offsets from the virtual base last year, but those patches never
made it upstream; so after some discussion with Tony about the best
all-around approach, we'll just grit our teeth and duplicate the
structures.  The maintenance advantages of a single kernel config that
can compile and boot on OMAP2, 3, and 4 platforms are simply too
compelling.

This approach does have some nice benefits beyond multi-OMAP 2 kernel
support.  The runtime size of OMAP2420-specific and OMAP2430-specific
kernels is smaller, since unused clocks for the other OMAP2 chip will
no longer be compiled in.  (At some point we will mark the clock data
__initdata and allocate it during registration, which will eliminate
the runtime memory advantage.)  It also makes the clock trees slightly
easier to read, since 2420-specific and 2430-specific clocks are no
longer mixed together.

This patch also splits 2430-specific clock code into its own file,
mach-omap2/clock2430.c, which is only compiled in for 2430 builds -
mostly for organizational clarity.

While here, fix a bug in the OMAP2430 clock tree: "emul_ck" was
incorrectly marked as being 2420-only, when actually it is present on
both OMAP2420 and OMAP2430.

Thanks to Tony for some good discussions about how to approach this
problem.

657ebfadc1 OMAP3/4 clock: split into per-chip family files
clock34xx_data.c now contains data for the OMAP34xx family, the
OMAP36xx family, and the OMAP3517 family, so rename it to
clock3xxx_data.c.  Rename clock34xx.c to clock3xxx.c, and move the
chip family-specific clock functions to clock34xx.c, clock36xx.c, or
clock3517.c, as appropriate.  So now "clock3xxx.*" refers to the OMAP3
superset.

The main goal here is to prepare to compile chip family-specific clock
functions only for kernel builds that target that chip family.  To get to
that point, we also need to add CONFIG_SOC_* options for those other
chip families; that will be done in future patches, planned for 2.6.35.

OMAP4 is also affected by this.  It duplicated the OMAP3 non-CORE DPLL
clkops structure.  The OMAP4 variant of this clkops structure has been
removed, and since there was nothing else currently in clock44xx.c, it
too has been removed -- it can always be added back later when there
is some content for it.  (The OMAP4 clock autogeneration scripts have been
updated accordingly.)

1a3377176b OMAP2 clock: drop CONFIG_PARTICIPANT clock flag
It turns out that the only purpose of the CONFIG_PARTICIPANT clock
flag is to prevent omap2_clk_set_rate() and omap2_clk_set_parent()
from being executed on clocks with that flag set.  The rate-changing
component can be more directly accomplished by dropping the .set_rate
and .round_rate function pointers from those CONFIG_PARTICIPANT struct
clks.  As far as the parent-changing component is concerned, it turns
out that none of the CONFIG_PARTICIPANT clocks have multiple parent
choices, so all that is necessary is for omap2_clk_set_parent() to
bail out early if the new parent is equal to the old parent.
Implement this change and get rid of the flag, which has always had a
confusing name (it appears to be a Kconfig option, falsely).

94297784ee OMAP2xxx clock: GFX functional clock rates are not independently changeable
According to the OMAP242x TRM Rev X Figure 5-15 "Clock Output Control
- Functional Clocks 2", the GFX functional clocks should be marked
both DELAYED_APP and CONFIG_PARTICIPANT, meaning that their rates must
be reprogrammed as part of a larger OPP set change.

93340a2294 OMAP2/3/4 clock: fix DPLL multiplier value errors; also copyrights, includes, documentation
The maximum DPLL multiplier (M) values for OMAP2xxx and OMAP3xxx are
one increment higher than they should be.  See for example the
OMAP242x TRM Rev X Section 5.10.6 "Clock Generator Registers" and the
OMAP36xx TRM Rev C Table 3-202 "CM_CLKSEL1_PLL".  Programming a 0 into
the DPLL's M register bitfield is valid for OMAP2/3 and indicates that
the DPLL should enter MN-bypass mode.  Also, increase the minimum
multiplier (M) value for the DPLL rate rounding code from 1 to 2, to
ensure that it does not inadvertently put the DPLL into bypass.

Note that the register documentation in the OMAP2xxx and OMAP3xxx TRMs
does not make clear that the actual DPLL divider value (the "N") is
the content of the appropriate register bitfield for the N value,
_plus one_.  (In other words, an N register bitfield of 0 indicates a
DPLL divider value of 1.)  This is only clearly documented in the
OMAP4430 TRM, in, for example, OMAP4430 TRM Rev A Table 3-1167
"CM_CLKSEL_DPLL_USB".

While here, update copyrights, add kerneldoc for struct dpll_data,
drop the unused struct dpll_data.max_tolerance field, remove some
unnecessary #includes in DPLL-related code, and replace the #include
of <linux/module.h> with <linux/list.h>, which is what was really
needed.  The OMAP4 clock autogenerator script has been updated
accordingly.

7356f0b26b OMAP3 clock: add support for 192Mhz DPLL4M2 output
In 3630, DPLL4M2 output can be 96MHz or 192MHz (for SGX to run at
192). This patch has changes to support this feature. 96MHz clock is
generated by dividing 192Mhz clock by 2 using CM_CLKSEL_CORE register.
SGX can select Core Clock, 192MHz clock or CM_96M_FCLK as it's
functional clock. In summary changes done are:
1. Added a feature called omap3_has_192mhz_clk and enabled for 3630
2. Added a new clock node called omap_192m_alwon_ck
3. Made omap_96m_alwon_fck to derive its clock from omap_192m_alwon_ck

a7e069fc5a OMAP3630: Clock: Workaround for DPLL HS divider limitation
This patch implements a workaround for the DPLL HS divider limitation
in OMAP3630 as given by Errata ID: i556.

Errata:
When PWRDN bit is set, it resets the internal HSDIVIDER divide-by value (Mx).
The reset value gets loaded instead of the previous value.
The following HSDIVIDERs exhibit above behavior:
. DPLL4 : M6 / M5 / M4 / M3 / M2 (CM_CLKEN_PLL[31:26] register bits)
. DPLL3 : M3 (CM_CLKEN_PLL[12] register bit).

Work Around:
It is mandatory to apply the following sequence to ensure the write
value will
be loaded in DPLL HSDIVIDER FSM:
The global sequence when using PWRDN bit is the following:
. Disable Mx HSDIVIDER clock output related functional clock enable bits
        (in CM_FCLKEN_xxx / CM_ICLKEN_xxx)
. Enable PWRDN bit of HSDIVIDER
. Disable PWRDN bit of HSDIVIDER
. Read current HSDIVIDER register value
. Write different value in HSDIVIDER register
. Write expected value in HSDIVIDER register
. Enable Mx HSDIVIDER clock output related functional clocks
        (CM_FCLKEN_xxx / CM_ICLKEN_xxx)

358f0e630d OMAP3: hwmod: support to specify the offset position of various SYSCONFIG register bits.
In OMAP3 Some modules like Smartreflex do not have the regular sysconfig
register.Instead clockactivity bits are part of another register at a
different bit position than the usual bit positions 8 and 9.

In OMAP4, a new scheme is available  due to the new protocol
between the PRCM and the IPs. Depending of the scheme, the SYSCONFIG
bitfields position will be different.
The IP_REVISION register should be at offset 0x00.
It should contain a SCHEME field. From this we can determine whether
the IP follows legacy scheme or the new scheme.

31:30 SCHEME  Used to distinguish between old scheme and current.
 Read 0x0:  Legacy protocol.
 Read 0x1:  New PRCM protocol defined for new OMAP4 IPs

For legacy IP
 13:12 MIDLEMODE
 11:8  CLOCKACTIVITY
 6     EMUSOFT
 5     EMUFREE
 4:3   SIDLEMODE
 2     ENAWAKEUP
 1     SOFTRESET
 0     AUTOIDLE

For new OMAP4 IP's, the bit position in SYSCONFIG is (for simple target):
 5:4   STANDBYMODE (Ex MIDLEMODE)
 3:2   IDLEMODE (Ex SIDLEMODE)
 1     FREEEMU (Ex EMUFREE)
 0     SOFTRESET

Unfortunately In OMAP4 also some IPs will not follow any of these
two schemes. This is the case at least for McASP, SmartReflex
and some security IPs.

This patch introduces a new field sysc_fields in omap_hwmod_sysconfig which
can be used by the hwmod structures to specify the offsets for the
sysconfig register of the IP.Also two static structures
omap_hwmod_sysc_type1 and omap_hwmod_sysc_type2 are defined
which can be used directly to populate the sysc_fields if the IP follows
legacy or new OMAP4 scheme. If the IP follows none of these two schemes
a new omap_hwmod_sysc_fields structure has to be defined and
passed as part of omap_hwmod_sysconfig.

Current implementation defines clock idle state indicators based on the
cpu information (cpu_is_omap24xx() or cpu_is_omap34xx()) in a system wide
manner. This patch extends the find_idlest() function in clkops to pass
back the idle state indicator for that clock, thus allowing idle state
indicators to be defined on a per clock basis if required.

This is specifically needed on AM35xx devices as the new IPSS clocks
indicates the idle status (0 is idle, 1 is ready) in a way just
opposite to how its handled in OMAP3 (0 is ready, 1 is idle).

cde08f81b1 OMAP3 PM: Adding counters for power domain logic off and mem off during retention.
This patch adds counters to keep track of whether the powerdomain
logic or software controllable memory banks are turned off when
the power domain enters retention. During power domain retention
if logic gets turned off, the scenario is known as Open Switch Retention.
Also during retention s/w controllable memory banks of a power
domain can be chosen to be kept in retention or off.

This patch adds one counter per powerdomain to track the power domain
logic state during retention. Number of memory bank state counters
added depends on the number of software controllable memory banks
of the powerdomain. To view these counters do

0007122ad8 OMAP: omap_device: add omap_device_is_valid()
The omap_device struct contains a 'struct platform_device'.  Normally,
converting a platform_device pointer to an omap_device pointer
consists of simply doing a container_of(), as is done currently by the
to_omap_device() macro.

However, if this is attempted when using platform_device that has not
been created as part of the omap_device creation, the container_of()
will point to a memory location before the platform_device pointer
which will contain random data.

Therefore, we need a way to detect valid omap_device pointers.  This
patch solves this by using the simple magic number approach.

111588f830 arm/imx/iomux-v1: rename header file
Addionally make iomux-mx*.h headers stand-alone and similar to iomux-v3
platform files should include their platform iomux header from now on.
For now iomux.h simply includes all iomux-v1 platform headers and so
provides compatibility until all files are converted.
