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.

Mark Brown 43f1069ef9 ARM: S3C64XX: Separate out regulator and frequency latencies
Currently the transition latency reported by the S3C64xx cpufreq
driver includes both the time for the CPU to reclock itself and
the time for a regulator to change voltage. This means that if
a regulator is not in use then the transition latency reported
is excessively high.

In future the regulator API will be extended to report latencies
so the driver will be able to query the performance of a given
regulator.

Mark Brown 42015c133b ARM: SMDK6410: Hook up regulator supplies for WM8580
DVDD is supplied by supplies derived from the PMIC, AVDD and PVDD are
supplied from the main wall supply on the base board which runs at
5V. No option is currently supported for running without a PMIC card,
the assumption is that the regulator API will be built out when no
soft PMIC card is in use.

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
enabled.

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.

range single board computer that unleashes laptop-like performance and
expandability without the bulk, expense, or noise of typical desktop
machines. Its architecture shares much in common with other OMAP3 boards.

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.

DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY

PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds
support for RMII PHY.

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

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.

Sandeep Paulraj 6b0cf4e93c DaVinci: EDMA: Fix Bug in edma_alloc_cont_slots API
The edma_alloc_cont_slots API is used for obtaining a set of
contiguous slots. When we use the "_ANY" option with this
API, by definition of this option it is suppossed to start
looking for a set of contiguous slots starting from slot 64 for
DaVinci SOC's and 32 for DA8xx SOC's. This has been explained in
the API description in the driver itself. So when we use the
"_ANY" option with this API, the slot number passed as
an argument should be a "don't care".
This patch takes care of this condition mentioned above.
When checking to see if the starting slot is a valid number,
it checks to make sure that the "_ANY" option is not used.

On ARMv7, it is invalid to map the same physical address multiple times

However, DMA memory maps it as "strongly ordered".  Fix this by introducing

Jean PIHET 3336f4f08e ARM: 5793/1: ARM: Check put_user fail in do_signal when enable OABI_COMPAT
Using OABI, the call to put_user in do_signal can fail causing the
calling app to hang.

The solution is to check if put_user fails and force the app to
seg fault in that case.

Tested with multiple sleeping apps/threads (using the nanosleep syscall)
and suspend/resume.

Daniel Mack 52939c03e5 ARM: MX3: fix CPU revision number detection
The macro mx31_revision() used to take the global variable system_rev to
determine the CPU revision number. However, this number is expected to
be set by the bootloader and is usually zero (at least on my MX31 based
boards here). More than that, it is usually taken to identify the
board's revision, not the CPU's.

Fix that by reading the the CPU's SREV register instead.

Right now, mx31_read_cpu_rev() is called from mx31_clocks_init() which
is admittedly not a good place for it. However, we need to enable the
IIM clock first, and the clock code also has conditional code that
depends on mx31_revision() returning the right thing.

vikram pandita 5f35fbe8b8 omap3: zoom: Introduce zoom3 board support
Zoom3 is the next version of Zoom2 board.
There has been a silicon update from zoom2 to zoom3.
        Zoom2 has OMAP34xx
        Zoom3 has OMAP3630 [1]
Zoom3 = OMAP3630 SOM board [2] + same zoom2 main board [3] + same debugboard

Zoom3 has a SDRAM part from Hynix
Zoom2 had SDRAM part from micron

Hynix memory timings are contributed by:
Chalhoub, Nicole and Bour, Vincent

Reuse the zoom2 files as much for zoom3, as at board level,
there is no change at all.

The I2C-1 bus frequency on zoom2/zoom3/sdp3630 should be 2.4 MHz.
The speed is limited by TWL5030/GAIA; a higher speed could lead to errors
on the interface.

The maximum I2C speed depends on the system clock for GAIA:
2.2 MHz (sys-clk = 19.2 MHz)
2.4 MHz (sys-clk = 26 MHz)
2.9 MHz (sys-clk = 38.4 MHz)

For Zoom2/Zoom3/SDP3630 the system clock is 26Mhz
and hence choose 2.4Mhz for I2C1 bus speed

The image size is now 1.9 MB down from 2.4 MB earlier, and
the number of modules is 8, down from 203. Build time also
scales proportionally.

Other support (OneNAND, etc) can be enabled as needed.

Charulatha V 058af1ea98 omap: GPIO module enable/disable
This patch disables a GPIO module when all pins of a GPIO
module are inactive (clock gating forced at module level) and
enables the module when any gpio in the module is requested.

The module is enabled only when "mod_usage" indicates that no GPIO
in that  module is currently active and the GPIO being requested
is the 1st one to be active in that module.

Each module would be disabled in omap_gpio_free() API when all
GPIOs in a particular module becomes inactive. The module is
re-enabled in omap_gpio_request() API when a GPIO is requested
from the module that was previously disabled.

Since individual GPIO's bookkeeping is added in this patch
via "mod_usage", the same is used in omap_set_gpio_debounce()
& omap_set_gpio_debounce_time() APIs to ensure that the gpio being
used is actually "requested" prior to being used (Nishant Menon's
<nm@ti.comSuggestion)

GPIO module level details are specific to hardware and hence
introducing this patch in low level layer (plat-omap/gpio.c)

Paul Walmsley 13a0322957 omap3: drop all IVA-related address base definitions
All of the OMAP3 IVA physical address macros in
plat-omap/include/plat/omap34xx.h are wrong[1]:

OMAP34XX_IVA_INTC_BASE: The IVA interrupt controller does not appear
to be accessible from the L3 interconnect, and in any case is
definitely not at 0x40000000; the latter address appears to be the
internal IVA physical address base for the OMAP2420's interrupt control[2].

OMAP34XX_DSP_BASE: The section of L3 physical address space mapped to
the IVA starts at 0x5c000000, not 0x58000000.

OMAP34XX_DSP_MEM_BASE: It's not clear what this refers to, but it's not
in the L3 IVA address space.

OMAP34XX_DSP_IPI_BASE: The Intrusive Port Interface is a relic from
the OMAP2420 days and no longer applies to OMAP3.

OMAP34XX_DSP_MMU_BASE: The DSP MMU is mapped at 0x5d000000, not 0x5a000000.


Nothing that uses these can possibly be working, so drop them.  When
future code needs these, correct versions can be added in.
