Sekhar Nori 39e1455004 davinci: am18x/da850/omap-l138: add support for higher speed grades
AM18x/DA850/OMAP-L138 SoCs have variants that can operate
at a maximum of 456 MHz at 1.3V operating point. Also the
1.2V operating point has a variant that can support a maximum
of 375 MHz.

This patch adds three new OPPs (456 MHz, 408 MHz and 372 MHz)
to the list of DA850 OPPs.

Not all silicon is qualified to run at higher speeds and
unfortunately the maximum speed the chip can support can only
be determined from the label on the package (not software
readable).

Because of this, we depend on the maximum speed grade information
to be provided to us in some board specific way. The board informs
the maximum speed grade information by setting the da850_max_speed
variable.

Sekhar Nori 6ef62f8204 davinci: am18x/da850/omap-l138: use 'NOM' voltage defined in datasheet as min voltage
For each DA850 OPP, the normal ('NOM') voltage defined in the tecnical
reference manual (TRM) is actually the minimum voltage the frequency
is supported at.

The minimum ('MIN') voltage defined in TRM is meant to take care of
voltage fluctuations and the device should not be run at this voltage
for extended periods of time.

Fix the OPP definitions to define the cvdd_min as the normal voltage
defined in the datasheet.

Sekhar Nori fca97b3337 davinci: cpufreq: bailout on regulator errors
Current cpufreq code does not consider errors that can occur while
changing voltage. Code to increase CPU  frequency goes ahead even in
the case the regulator has failed to increase the voltage. This leads
to hard error since lower voltages cannot support increased frequency.

Prevent this by not increasing frequency in case increasing voltage
is not successful.

Also, do not lower the voltage if changing the cpu frequency has failed
for some reason.

Note that we do not return error on failure to decrease voltage as
that is not a hard error.

This patch helps get rid of the following sparse warnings
of the type:

  CHECK   arch/arm/mach-davinci/da830.c
arch/arm/mach-davinci/da830.c:1026:3: warning: Initializer entry defined twice
arch/arm/mach-davinci/da830.c:1027:3:   also defined here

coming from the irq priorities array init.

Apart from one instance of genuinie repetition, most are are instances
of multiple #defines of the same interrupt number. I have not
removed the multiple definitions from the irq.h file in the hope
that someone might decide to use them as shared interrupts at some
point of time. The priority initialization however needs to be done
only once and hence has been corrected.

This patch allows for a more flexible ioremap() interception based on iotable
contents.

With this patch, the ioremap() interception code can properly translate
addresses only after davinci_soc_info has been initialized.  Consequently,
in soc-specific init functions, davinci_common_init() has to happen before any
ioremap() attempts. The da8xx init sequence has been suitably modified to meet
this restriction.

Cyril Chemparathy c78a5bc2e7 Davinci: watchdog reset separation across socs
The earlier watchdog reset mechanism had a couple of limitations.  First, it
embedded a reference to "davinci_wdt_device" inside common code.  This
forced all derived platforms (da8xx and tnetv107x) to define such a device.
This also would have caused problems in including multiple socs in a single
build due to symbol redefinition.

With this patch, davinci_watchdog_reset() now takes the platform device as an
argument.  The davinci_soc_info struct has been extended to include a reset
function and a watchdog platform_device.  arch_reset() then uses these
elements to reset the system in a SoC specific fashion.

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.

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.
