51c404b2c5 omap4: prcm: Fix the CPUx clockdomain offsets
CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base.
The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power
domain control register

Fix the same.

The autogen scripts is fixed thanks to Benoit Cousson

With the old value, the clockdomain code would access the
*_PWRSTCTRL.POWERSTATE field when it thought it was accessing the
*_CLKSTCTRL.CLKTRCTRL field.  In the worst case, this could cause
system power management to behave incorrectly.

cbc9438075 OMAP2+: clocksource: fix crash on boot when !CONFIG_OMAP_32K_TIMER
OMAP2+ kernels built without CONFIG_OMAP_32K_TIMER crash on boot after the
2.6.38 sched_clock changes:

[    0.000000] LR is at sched_clock_poll+0x2c/0x3c

Without CONFIG_OMAP_32K_TIMER, the kernel has an clockevent and
clocksource resolution about three orders of magnitude higher than
with CONFIG_OMAP_32K_TIMER set.  The tradeoff is that the lowest
power consumption states are not available.

Fix by calling init_sched_clock() from the GPTIMER clocksource init code.

97594b0f35 ARM: 6757/1: fix tlb.h induced linux/swap.h build failure
Commit

	06824ba (ARM: tlb: delay page freeing for SMP and ARMv7 CPUs)

introduced a build failure for builds with CONFIG_SWAP=n:

	In file included from arch/arm/mm/init.c:27:
	arch/arm/include/asm/tlb.h: In function 'tlb_flush_mmu':

as linux/swap.h doesn't include linux/pagemap.h but actually needs it
(see comments in linux/swap.h as to why this is.)

Fix that by #including <linux/pagemap.h> in <asm/pgalloc.h> as it's done
by x86.

ea68c00e26 OMAP2/3: clock: fix fint calculation for DPLL_FREQSEL
In OMAP35X TRM Rev 2010-05 Figure 7-18 "DPLL With EMI Reduction
Feature", it is shown that the internal frequency is calculated by
CLK_IN/(N+1). However, the value passed to _dpll_test_fint() is
already "N+1" since Linux is using the values to divide by. In the
technical reference manual, "N" is referring to the divider's register
value (0-127).

During power management testing, it was observed that programming the
wrong jitter correction value can cause the system to become unstable
and eventually crash.

06824ba824 ARM: tlb: delay page freeing for SMP and ARMv7 CPUs
We need to delay freeing any mapped page on SMP and ARMv7 systems to
ensure that the data is not accessed by other CPUs, or is used for
speculative prefetch with ARMv7.  This includes not only mapped pages
but also pages used for the page tables themselves.

This avoids races with the MMU/other CPUs accessing pages after they've
been freed but before we've invalidated the TLB.

dc810efb0c ARM: 6740/1: Place correctly notes section in the linker script
Commit 18991197b4 added --build-id
linker option when toolchain supports it. ARM one does, but for some
reason places the section at 0 when linker script doesn't mention it
explicitly.

The 1e621a8e37 worked around the problem
removing this section from binary image with explicit objcopy options,
but it still exists in vmlinux, confusing tools like debuggers and perf.

This problem was discussed here:
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
but the proposed changes to the linker script were substantial.

This patch simply places NOTES (36 bytes long, at least when compiled
with CodeSourcery toolchain) between data and bss, which seem to be
the right place (and suggested by the sample linker script in
include/asm-generic/vmlinux.lds.h).

It is enough to place it correctly in vmlinux (so debuggers are happy):

Section Headers:
  [11] .data             PROGBITS        c07ce000 7ce000 020fc0 00  WA  0   0 32

9a27c27ce4 ARM: 6743/1: errata: interrupted ICALLUIS may prevent completion of broadcasted operation
On versions of the Cortex-A9 prior to r3p0, an interrupted ICIALLUIS
operation may prevent the completion of a following broadcasted
operation if the second operation is received by a CPU before the
ICIALLUIS has completed, potentially leading to corrupted entries in
the cache or TLB.

This workaround sets a bit in the diagnostic register of the Cortex-A9,
causing CP15 maintenance operations to be uninterruptible.

885028e4ba ARM: 6741/1: errata: pl310 cache sync operation may be faulty
The effect of cache sync operation is to drain the store buffer and
wait for all internal buffers to be empty. In normal conditions, store
buffer is able to merge the normal memory writes within its 32-byte
data buffers.  Due to this erratum present in r3p0, the effect of cache
sync operation on the store buffer still remains when the operation
completes. This means that the store buffer is always asked to drain
and this prevents it from merging any further writes.

This can severely affect performance on the write traffic esp. on
Normal memory NC one.

The proposed workaround is to replace the normal offset of cache sync
operation(0x730) by another offset targeting an unmapped PL310
register 0x740.

edca314f27 ARM: mx23: dynamically allocate mx23 auart device
i.MX23 Reference Manaul starts auart index from 1 than 0.  Changing
the index to start from 0 requires corresponding changes on base
address, irq, and iomux definitions, and will probably confuse people
who reads codes and hardware documents together.

This patch introduced the field 'hwid' to distinguish the driver id
and controller id.  These two ids are different on mx23 while
identical on mx28.

15490ef8ff ARM: Avoid building unsafe kernels on OMAP2 and MX3
OMAP2 (armv6) and MX3 turn off support for the V6K instructions, which
when they include support for SMP kernels means that the resulting
kernel is unsafe on SMP and can result in corrupted filesystems as we
end up using unsafe bitops.

Re-enable the use of V6K instructions on such kernels, and let such
kernels running on V6 CPUs eat undefined instruction faults which will
be much safer than filesystem corruption.  Next merge window we can fix
this properly (as it requires a much bigger set of changes.)

e66a022a80 arm/ixp4xx: Rename FREQ macro to avoid collisions
FREQ is a ridiculously short name for a platform-specific macro in a
generic header, and it now conflicts with an enumeration in the
gspca/ov519 driver.

Also delete conditional reference to ixp4xx_get_board_tick_rate()
which is not defined anywhere.

Panda uses both twl6030 otg phy(vbus, id) and internal

twl6030 otg driver working since current otg code only supports
one global transceiver. Otherwise, musb doesn't work without

719078a6bf OMAP1: Fix non-working LCD on OMAP310
This patch fixes bug introduced in revision:

f8e9e98454
omap1: DMA: move LCD related code from plat-omap to mach-omap1

The code introduced by this patch didn't consider any other CPUs but OMAP1510,
which rendered OMAP310 -- which has the same LCD controller -- non-working. Use
cpu_is_omap15xx() instead of cpu_is_omap1510() to squash this issue.

Bug found on Palm Zire 71 hardware.

daf7aabcc1 OMAP3: Devkit8000: Change lcd power pin
This patch fixes a wrongly used lcd enable pin.

The Devkit8000 uses twl4030_ledA configured as output gpio only for
the lcd enable line. twl4030_gpio.1 is used through the generic
gpio functions while ledA is used via low level twl4030 calls.

This patch removes the low level calls and use the generic gpio functions
for initialization and use of ledA. This patch also fixes a bug where the
lcd would not power down when blanking.

Further this patch fixes an indentation issue. The comment line uses
eight whitespace and is replaced with a hard tab.

gpio_request + gpio_direction_output are replaced with gpio_request_one.
The return value of gpio_request_one is used to set the value of the
gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the
unsuccessful request. But already successful requested gpios are not freed.

Disable the initrd if the passed address already overlaps the reserved

that an initrd is located at mem+4MB, but this overlaps the BSS,
resulting in the kernels in-use BSS being freed.

This should be applied to v2.6.37-stable.

617fcc9802 OMAP3: PM: fix save secure RAM to restore MPU power state
Currently, on HS/EMU devices, MPU power state forced to on during PM
init by the save secure RAM code.  Rather than forcing the state of
MPU powerdomain to on, simply read the current value and restore it
after the ROM code has run.

This only affects the !CPUidle case since when CPUidle is enabled, the
MPU power state is dynamically changed by CPUidle.  In the !CPUidle
case, MPU power state is initialized once at init and never touched.

d14dd7e20d ARM: oprofile: Fix backtraces in timer mode
Always allow backtraces when using oprofile on ARM, even if a PMU
isn't present. Restores functionality originally introduced in commit
1b7b56982f ("oprofile: Always allow
backtraces on ARM") by Richard Purdie.

It is not that obvious, but there is now only one oprofile_arch_init()
function. So the .backtrace callback is available also in timer mode.

Implemented by removing code and using stubs for oprofile_perf_{init,
exit} provided by <linux/oprofile.h>. This allows cleaning of other
architecture specific implementations too.

ac751efa6a console: rename acquire/release_console_sem() to console_lock/unlock()
The -rt patches change the console_semaphore to console_mutex.  As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()

This commit makes things use more neutral function names which dont make
implications about the underlying lock.

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()

This patch also paves the way to switching console_sem from a semaphore to
a mutex.

fd015480c2 ARM: 6636/1: ep93xx: default multiplexed gpio ports to gpio mode
The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface
peripheral.  At power-up they default into non-GPIO mode with the Key
Matrix controller enabled so these ports are unusable for GPIO.  Note
that the Keypad Interface peripheral is only available in the EP9307,
EP9312, and EP9315 processor variants.

The keypad support will clear the DeviceConfig bits appropriately to
enable the Keypad Interface when the driver is loaded.  And, when the
driver is unloaded it will set the bits to return the ports to GPIO mode.

To make these ports available for GPIO after power-up on all EP93xx
processor variants, set the KEYS and GONK bits in the DeviceConfig
register.

Similarly, the E, G, and H ports are multiplexed with the IDE Interface
peripheral.  At power-up these also default into non-GPIO mode.  Note
that the IDE peripheral is only available in the EP9312 and EP9315
processor variants.

Since an IDE driver is not even available in mainline, set the EONIDE,
GONIDE, and HONIDE bits in the DeviceConfig register so that these
ports will be available for GPIO use after power-up.

baaece2245 ARM: 6635/2: Configure reference clock for Versatile Express timers
Timers on Versatile Express mainboard are used as system clock/event
sources. Driver assumes that they are clocked with 1MHz signal.
Old V2M firmware apparently configured it by default, but on newer
boards one can observe that "sleep 1" command takes over 30 seconds
to finish, as the timers are fed with 32kHz instead...

This patch performs required magic and also removes code clearing
timer's control registers, as exactly the same operations are
performed by the timer driver few jiffies later.

As no one seems to really know which configuration options tie up with

out.  After discussion with some folk in linaro, I think I have this
nailed.

The names are updated to use the name on the front of the appropriate
board user guide for the various baseboards, which I've taken to be
the official name for each board.

I haven't significantly updated the descriptions for the tiles as that
is even less clear - as far as I can see on ARMs website, there is no
Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S,

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

4fb699b408 omap: DMA: clear interrupt status correctly
When clearing the DMA channel, clear all status bits.

When handling a DMA interrupt, clear only the interrupt
status bits that have been read and are passed to the
channel's interrupt handler, not every status bit.

4912cf04b2 omap1: Fix sched_clock implementation when both MPU timer and 32K timer are used
Earlier patches select HAVE_SCHED_CLOCK for omaps. To have working sched_clock
also for MPU timer, we need to implement it in a way where the right one gets
selected during the runtime.

05b5ca9b10 omap1: Fix booting for 15xx and 730 with omap1_defconfig
For omap15xx and 730 we need to use the MPU timer
as the 32K timer is not available. For omap16xx
we want to use the 32K timer because of PM. Fix this
by allowing to build in both timers.
