This patch extends the smartreflex framework to support
OMAP4. The changes are minor like compiling smartreflex Kconfig
option for OMAP4 also, and a couple of OMAP4 checks in
the smartreflex framework.
The change in sr_device.c where new logic has to be introduced
for reading the efuse registers is due to the fact that in OMAP4
the efuse registers are 24 bit aligned. A __raw_readl will
fail for non-32 bit aligned address and hence the 8-bit read
and shift.

to increase or decrease the voltage.
This patch adds smartreflex class 3 driver. This driver hooks
up with the generic smartreflex driver smartreflex.c to abstract
out class specific implementations out of the generic driver.
Class3 driver is chosen as the default class driver for smartreflex.
If any other class driver needs to be implemented, the init of that
driver should be called from the board file. That way the new class driver

Class-1: Boot-Time Software Calibration
Class-2: Continuous Software Calibration
Class-3: Continuous Hardware Calibration

Smartreflex driver can be enabled through a Kconfig option
"SmartReflex support" under "System type"->"TI OMAP implementations" menu.
Smartreflex autocompensation feature can be enabled runtime through

This patch adds voltage driver support for OMAP3. The driver
allows configuring the voltage controller and voltage
processors during init and exports APIs to enable/disable
voltage processors, scale voltage and reset voltage.
The driver maintains the global voltage table on a per
VDD basis which contains the various voltages supported by the
VDD along with per voltage dependent data like smartreflex
efuse offset, errminlimit and voltage processor errorgain.
The driver also allows the voltage parameters dependent on the
PMIC to be passed from the PMIC file through an API.
The driver allows scaling of VDD voltages either through
"vc bypass method" or through "vp forceupdate method" the
choice being configurable through the board file.

[khilman: fixed link error for OMAP2-only defconfig]
Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
The x86 arch has shifted its use of the nmi_watchdog from a
local implementation to the global one provide by
kernel/watchdog.c. This shift has caused a whole bunch of
compile problems under different config options. I attempt to
simplify things with the patch below.
In order to simplify things, I had to come to terms with the
meaning of two terms ARCH_HAS_NMI_WATCHDOG and
CONFIG_HARDLOCKUP_DETECTOR. Basically they mean the same thing,
the former on a local level and the latter on a global level.
With the old x86 nmi watchdog gone, there is no need to rely on
defining the ARCH_HAS_NMI_WATCHDOG variable because it doesn't
make sense any more. x86 will now use the global
implementation.
The changes below do a few things. First it changes the few
places that relied on ARCH_HAS_NMI_WATCHDOG to use
CONFIG_X86_LOCAL_APIC (the former was an alias for the latter
anyway, so nothing unusual here). Those pieces of code were
relying more on local apic functionality the nmi watchdog
functionality, so the change should make sense.
Second, I removed the x86 implementation of
touch_nmi_watchdog(). It isn't need now, instead x86 will rely
on kernel/watchdog.c's implementation.
Third, I removed the #define ARCH_HAS_NMI_WATCHDOG itself from
x86. And tweaked the include/linux/nmi.h file to tell users to
look for an externally defined touch_nmi_watchdog in the case of
ARCH_HAS_NMI_WATCHDOG _or_ CONFIG_HARDLOCKUP_DETECTOR. This
changes removes some of the ugliness in that file.
Finally, I added a Kconfig dependency for
CONFIG_HARDLOCKUP_DETECTOR that said you can't have
ARCH_HAS_NMI_WATCHDOG _and_ CONFIG_HARDLOCKUP_DETECTOR. You can
only have one nmi_watchdog.
Tested with
ARCH=i386: allnoconfig, defconfig, allyesconfig, (various broken
configs) ARCH=x86_64: allnoconfig, defconfig, allyesconfig,
(various broken configs)
Hopefully, after this patch I won't get any more compile broken
emails. :-)
v3:
changed a couple of 'linux/nmi.h' -> 'asm/nmi.h' to pick-up correct function
prototypes when CONFIG_HARDLOCKUP_DETECTOR is not set.

This patch adds a pca953x platform device for the tca6416 found on the evm
baseboard. The tca6416 is a GPIO expander, also found on the UI board at a
separate I2C address. The pins of the baseboard IO expander are connected to
software reset, deep sleep enable, test points, a push button, DIP switches and
LEDs.
Add support for the push button, DIP switches and LEDs and test points (as
free GPIOs). The reset and deep sleep enable connections are reserved by the
setup routine so that userspace can't toggle those lines.
The existing tca6416-keypad driver was not employed because there was no

This patch adds EV_KEYs for each of the 8 pushbuttons on the UI board via a
gpio-key device.
The expander is a tca6416; it controls the SEL_{A,B,C} lines which enable and
disable the peripherals found on the UI board in addition to the 8 pushbuttons
mentioned above. The reason the existing tca6416-keypad driver is not employed
is because there was no aparent way to keep the gpio lines used as
SEL_{A,B,C} registered while simultaneously registering the pushbuttons as a
tca6416-keypad instance.
Some experimentation with the polling interval was performed; we were searching
for the largest polling interval that did not affect the feel of the
responsiveness of the buttons. It is very subjective but 200ms seems to be a
good value that accepts firm pushes but rejects very light ones. The key values
assigned to the buttons were arbitrarily chosen to be F1-F8.
