(Updated usage of NR_CPUS instead of num_possible_cpus() after Russell's remark)
This patch adds SMP platform files support for OMAP4430SDP. TI's OMAP4430
SOC is based on ARM Cortex-A9 SMP architecture. It's a dual core SOC
with GIC used for interrupt handling and SCU for cache coherency.

Hi,
Let's say I have a device that requires power from a regulator, like
OMAP3430 SDP Sharp LCD's Vcc.
Then I have two boards with the same device. One board gives power to
the device from an always-on regulator, like SDP does with VBAT going to
the LCD. The other board gives power to the device
Hi,
This series contains a set of patches which implement new 3430 errata, and some
optimizations
and fixes in the SR driver and DVFS path.
These apply on the latest 'pm' branch and are validated on a 3430SDP platform.

This patch disables OMAP FB driver from the pm defconfig
for SDP as it seems to gate sleep and throw some irq errors
omapfb omapfb: irq error status 0062
omapfb omapfb: irq error status 00c2
omapfb omapfb: irq error status 0060
Also ondemand CPUFreq governor support is enabled.

This patch makes sure that VDD2 dvfs always happens at
a higher VDD1 OPP, hence bringing down the VDD2 DVFS latency
to a large extent.
Having a smaller VDD2 dvfs latency helps drivers which are sensitive
to the time during which SDRAM is inaccessible due to SDRC iclk being
disabled.
This patch adds a Wakeup dependency of PER domain on WKUP
domain as a Workaround for a OMAP3430 limitation which causes
PER domain GPIO's to drive random values while coming back
from OFF mode. This limitation applies to all silicon rev's
of OMAP3430.

This patch removes the worst case T2 SMPS stabilization delay
of 360 us (needed for a 0v to 1.35 switch) and adds calculated
delay based on the actual volatge switch.
The delay is based on the T2 SMPS slew rate of 4mV/uS.
Each step based on VSEL difference corresponds to 12.5 mv
Hence the formula
This patch implements locking using the semaphore in scratchpad

Hi,
How can I profile and do some performance tests on the linux-omap
kernel sources, and identify the 10 slowest methods for a specific
subsystem, say DSS2?
I used to use IBM Rational Test-Real-Time before, to do these kinds of
tests for embedded software, but don't have access to these

Hi,
I am getting SYNC LOSTerror on OMAP development board ( LDP ), this happens
when I enable mirroring by a command
#echo 1 /sys/class/graphics/fb0/mirror
In brief, recently I ported board related funtions to support both LCD and TV
displays on Omap LDP, mirroring works on TV but not LCD.
