Commit c971ff18 'leds: leds-pwm: Defer led_pwm_set() if PWM can sleep'
fixed a crash when using a trigger with a pwm-led provided by an
external chip. Now it is safe to add the default trigger according
to board-overo.c.

On most OMAP3 platforms, the twl4030 IRQ line is connected to the
SYS_NIRQ line on OMAP.  Add another DTS include file
(twl4030_omap3.dtsi) for boards that hook up the twl4030 this way
to include.

This allows RTC wake from off-mode to work again on OMAP3-based
platforms with twl4030.  Tested on 3530/Beagle, 3730/Beagle-xM,
3530/Overo, 3730/Overo-STORM.

Special thanks to Florian Vaussard for suggesting use of preprocessor
feature.

Ensure the console uart (UART3) on these boards is mux'd correctly, and
IO ring wakeup is enabled.

This is needed for serial console wakeups when using DT boot.

Thanks to Florian Vaussard for suggestion to use preprocessor
features.

Replace /include/ by #include for OMAP2+ DT, in order to use the
C pre-processor, making use of #define features possible.

If a board isn't using twl4030, then dtc will complain about the missing
phandle (which is in twl4030.dtsi).  Move the phy declaration to the dts
files.

Add DT OPP table for OMAP34xx/35xx family of devices. This data is
decoded by OF with of_init_opp_table() helper function.

OPP data here is based on existing opp3xxx_data.c

Since the omap36xx OPP tables would be different from OMAP34xx/35xx,
introduce an new omap34xx.dtsi for 34xx/35xx specific entries and use
existing omap3.dtsi as the common dtsi file for all OMAP3 platforms.

This is in preparation to use generic cpufreq-cpu0 driver for device
tree enabled boot. Legacy non device tree enabled boot continues to
use omap-cpufreq.c and opp3xxx_data.c.

Add usb otg data node in omap4/omap3 device tree file. Also update
the node with board specific setting in omapx-<board>.dts file.
The dt data specifies among others the interface type (ULPI or UTMI),
mode which is mostly OTG, power that specifies the amount of power
this can supply when in host mode.

The information about usb otg node is available @

The Gumstix Overo is a computer on module using an OMAP3 processor.
This module must be plugged into an expansion board.

This patch adds a first device tree support for the Overo, using the
Tobi expansion board. The current support is able to boot and mount
the rootfs from MMC.

This patche also updates the omap3 dtb build target.

Currently working:
- mmc0 (on board microSD)
- i2c0 and i2c2 (i2c1 not used)
- led on GPIO
