Laurent Pinchart 3d49538364 ARM: dts: Split omap3 pinmux core device
The omap3_pmx_core pinmux device in the device tree handles the system
controller module (SCM) PADCONFS fonction. Its control registers are
split in two distinct areas, with other SCM registers in-between. Those
other registers can't thus be requested by other drivers as the memory
region gets reserved by the pinmux driver.

Split the omap3_pmx_core device tree node in two for the two memory
regions. The second region address and size depends on the SoC model.

The change in omap3.dtsi fixes an "external abort on non-linefetch" when
doing

cat /sys/kernel/debug/pinctrl/.../pins

on a Nokia N900.

Note that the core2 padconf region is different for 3430 vs 3630,
and does not exist on 3517 as noted by Nishanth Menon <nm@ti.com>.

Roger Quadros 30023a7e4f ARM: dts: omap3-beagle: Fix USB host on beagle boards (for 3.13)
Beagle (rev. C4) and Beagle-XM (all revs) need VAUX2 1.8V supply
for the USB PHY.

As the generic PHY driver can't handle more than one supply
at the moment, we configure this supply to be always on.
This will cause a very small power impact if the USB host subsystem
is not in use, about 76.86 micro-W + LDO power.

Older Beagle boards (prior to C4) don't have VAUX2 connected anywhere,
so there won't be any functional impact on those boards other than
some additional LDO power consumption.

Kevin Hilman f96884574d ARM: dts: TWL4030: fix mux and wakeup for SYS_NIRQ line
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.

Nishanth Menon a134be3406 ARM: dts: OMAP3: use twl4030 vdd1 regulator for CPU
Define VDD1 regulator in twl4030 DT and mark it as the supply for the
various OMAP34xx/35xx/36xx/37xx platforms (all use TWL4030 variants with
VDD1 supplying the CPU).

NOTE: This currently will use I2C1 bus communication path to set the
voltage in device tree boot. In the legacy non device tree boot, we
continue to use twl-common.c which bypasses I2C1 bus communication path
and uses I2C4 bus path using OMAP voltage libraries. We should
eventually be able to use I2C4 path once we have voltage regulator for
OMAP which is capable of using the voltage controller/voltage processor
IP blocks.

Nishanth Menon 1e633d713b ARM: dts: OMAP34xx/35xx: Add CPU OPP table
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.

Jon Hunter 5a8095e9d0 ARM: dts: Add omap3-beagle.dts
Add a minimal dts for original OMAP3430/3530 version of the Beagle board. This
version of the Beagle board has 256MB of DDR and features the same TWL4030
power management IC (PMIC) as the Beagle board XM.

Given that the Beagle and Beagle-XM boards use the same PMIC, move the
definition of the VSIM regulator into the TWL4030.dtsi file so that we do not
need to duplicate in the Beagle board dts file.

This has been boot tested on an OMAP3530 Beagle board and verifing that the
SD/MMC interface is working with a SD card.

V2 changes
- Rebased upon of devel-dt
- Corrected copyright date in omap3-beagle.dts file
- Added LED support after verifing that Beagle and Beagle XM have the same LED
  configuration
