Krzysztof Hałasa 6e30de84ab IXP4xx: change the timer base frequency to 66.666000 MHz.
Clock generators used by IXP4xx processors are usually 33.333 MHz, sometimes
33.33 MHz and few platforms use 33 MHz. The timers tick twice as fast,
that means 66.666, 66.66 or 66 MHz. Current 66.666666 MHz means 10 ppm
offset from the usual 66.666 MHz.

Russell King 6060e8df51 ARM: I-cache: flush executable mappings in flush_cache_range()
Dirk Behme reported instability on ARM11 SMP (VIPT non-aliasing cache)
caused by the dynamic linker changing protection on text pages to write
GOT entries.  The problem is due to an interaction between the write
faulting code providing new anonymous pages which are incoherent with
the I-cache due to write buffering, and the I-cache not having been
invalidated.

a4db94d plugs the hole with the data cache coherency.  This patch
provides the other half of the fix by flushing the I-cache in
flush_cache_range() for VM_EXEC VMAs (which is what we have when the
region is being made executable again.)  This ensures that the I-cache
will be up to date with the newly COW'd pages.

Note: if users are writing instructions, then they still need to use
the ARM sys_cacheflush API to ensure that the caches are correctly
synchronized.

Russell King ea201dbb78 ARM: I-cache: avoid flushing in flush_cache_mm()
flush_cache_mm() is called in two cases:
1. when a process exits, just before the page tables are torn down.
   We can allow the stale lines to evict themselves over time without
   causing any harm.

2. when a process forks, and we've allocated a new ASID.
   The instruction cache issues are dealt with as pages are brought
   into the new process address space.  Flushing the I-cache here is
   therefore unnecessary.

However, we must keep the VIPT aliasing D-cache flush to ensure that
any dirty cache lines are not written back after the pages have been
reallocated for some other use - which would result in corruption.

The I and D caches for copy-on-write pages on processors with

Mark Brown e9c08f0d57 ARM: S3C64XX: Redo voltage ranges for cpufreq
The documentation for the S3C6410 CPU voltage scaling is rather
unclear, with omitted values for several speed settings. Originally
the code was using only quoted values, resulting in some fairly odd
settings. The S3C6410 is also unusual in that the both the maximum
and minimum voltages quoted scale as the frequency rises, rather
than just the minimum voltage.

Clean this up a bit by always using the specified typical settings
as the minimum voltage (ignoring any specified minimum voltage) in
order to avoid running near the edge of the processor capabilities.
Also use the next quoted maximum voltages rather than the typical
voltages where no maximum voltage is quoted, allowing operation on
a greater range of systems.

To ease merge issues since this uses the newly added dev_name supply
configuration from the regulator API (currently in -next only) the
fixed voltage regulator is ifdefed out when the regulator API is not

Add a driver to provide DVS for the Simtec Osiris module to reduce
the power consumption whilst idling.

The DVS driver alters the voltage supplied to the ARM core depending
on the frequency it is running at. The driver itself does not do any
of the frequency alteration, which is left up to the cpufreq driver.

Russell King cc155c6f2c [ARM] pxa: allow platforms to control which uarts are registered
For some platforms, it is inappropriate to register all PXA UARTs.
In some cases, the UARTs may not be used, and in others we may want
to avoid registering the UARTs to allow other drivers (eg, FICP) to
make use of the UART.

In addition, a while back there was a request to be able to pass
platform data to the UART driver.

This patch enables all of this by providing functions platforms can
call to register each individual UART.

Ilya Loginov 2d4dc890b5 block: add helpers to run flush_dcache_page() against a bio and a request's pages
Mtdblock driver doesn't call flush_dcache_page for pages in request.  So,
this causes problems on architectures where the icache doesn't fill from
the dcache or with dcache aliases.  The patch fixes this.

The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid
pointless empty cache-thrashing loops on architectures for which
flush_dcache_page() is a no-op.  Every architecture was provided with this
flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is
equal 1 or do nothing otherwise.

See "fix mtd_blkdevs problem with caches on some architectures" discussion
on LKML for more information.

Sekhar Nori 13d5e27a44 davinci: DA850/OMAP-L138: avoid using separate initcall for initializing regulator
Using a device_initcall() for initializing the voltage regulator
on DA850 is not such a good idea because it gets called for all
platforms - even those who do not have a regulator implemented.
This leads to a big fat warning message during boot-up when
regulator cannot be found.

Instead, tie initialization of voltage regulator to cpufreq init.
Define a platform specific init call which in case of DA850 gets
used for initializing the regulator. On other future platforms it
can be used for other purposes.

The patch adds support for DaVinci cpu idle driver.

Two idle states are defined:
1. Wait for interrupt
2. Wait for interrupt and DDR self-refresh (or power down)

Some DaVinci SoCs support putting DDR in self-refresh (eg Dm644x, DM6467)
while others support putting DDR in self-refresh and power down (eg DM35x,
DA8xx).

Putting DDR (or mDDR) in power down saves more power than self-refresh.

The patch has been tested on DA850/OMAP-L138 EVM.

Sudhakar Rajashekhara 1ef203c324 davinci: DA8XX/OMAP-L1XX: fix compiler warning
When kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y
option, using da8xx_omapl_defconfig, some warnings are
observed:

WARNING: vmlinux.o(.text+0xc2a4): Section mismatch in reference
from the function da850_evm_setup_nor_nand() to the variable
.init.data:da850_nand_pins
The function da850_evm_setup_nor_nand() references
the variable __initdata da850_nand_pins.
This is often because da850_evm_setup_nor_nand lacks a __initdata
annotation or the annotation of da850_nand_pins is wrong.

This patch fixes such warnings.

Sekhar Nori bae105879f davinci: DA850/OMAP-L138 EVM: implement autodetect of RMII PHY
Implement autodetection of RMII PHY by shifting the decision
to use the RMII PHY to da850_evm_ui_expander_setup() from
da850_evm_init() earlier.

Without this patch, selecting RMII PHY in the UI expander menu
will make the MII PHY unusable even though UI board is not
connected.

The actual configuration and registration of the EMAC device
is delayed to device_initcall() so it happens after the UI card
detection is complete.

Chaithrika U S 2206771c43 davinci: RMII support for DA850/OMAP-L138 EVM
DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY
is enabled by proper programming of the IO Expander (TCA6416) ports. Also for
RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the
PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds
support for RMII PHY.

This patch also adds a menuconfig option to select one or no peripheral
connected to expander. Currently, sub-options in this menu are RMII and no
peripheral.This menuconfig option is similar to the one present for UI card on
DA830/OMAP-L137 EVM.

Sekhar Nori 683b1e1f0e davinci: DA850/OMAP-L138: add frequency scaling support
Adds basic frequency scaling support for DA850/OMAP-L138.

Currently, frequency scaling only on PLL0 is supported. No scaling of PLL1
as yet.

Peripherals like MMC/SD which have a clock input synchronous with
ARM clock will not work well since the clock will change behind their backs.
Support for notification to such devices to adjust themselves to the
new frequency will be added in later patches. Current defconfigs keep
CPUFreq disabled so it will not affect normal operation.

The OPP defintions assume clock input of 24MHz to the SoC. This is inline
with hardcoding of input frequency in the <soc>.c files. At some point
this will need to move into board dependent code as new boards appear with
a different reference clock.

Tested on OMAP-L138 EVM with ondemand governer and a shell script to
vary processor load.
