This adds support for CompuLab SBC-T3530, also known as cm-t3730:

http://compulab.co.il/products/sbcs/sbc-t3530/

It seems that with the sbc-3xxx mainboard is also used on
SBC-T3517 and SBC-T3730 with just a different CPU module:

http://compulab.co.il/products/sbcs/sbc-t3517/
http://compulab.co.il/products/sbcs/sbc-t3730/



So let's add a common omap3-sb-t35.dtsi and then separate SoC
specific omap3-sbc-t3730.dts, omap3-sbc-t3530.dts and
omap3-sbc-t3517.dts.

I've tested this with SBC-T3730 as that's the only one I have.
At least serial, both Ethernet controllers, MMC, and wl12xx WLAN
work.

Note that WLAN seems to be different for SBC-T3530. And SBC-T3517
may need some changes for the EMAC Ethernet if that's used
instead of the smsc911x.

As we currently need to support a mix of legacy platform data and
device tree intialized data, let's make sure things keep working
for the TWL GPIOs.

Mostly the issue is caused by the fact that DSS does not yet have
device tree bindings, so we need to rely on the TWL GPIO callback
for setting up things like LCD backlight for some boards.

As of_platform_populate() for the TWL GPIO is called by twl-core
after the I2C bus has been initialized, we cannot pass the auxdata
table from the board init code to twl-core like we used to with
just legacy platform data.

So let's use the omap_device bus hook to patch in the platform
data for TWL GPIO until we have sorted out the issues with the
TWL GPIOs and device tree bindings.

The other option was be to initialize twl core using legacy
platform data, which seems like a step backwards as we're moving
to device tree only initialization.  And we really don't want to
add custom configuration functions to the TWL GPIO driver either
for this.

On am3517 there are some extra devices compared to omap3.dtsi that

file.

Signed-off-by: Tony Lindgren <tony@atomide.com>

We have some device tree properties where the ti,hwmod have multiple
values:

am33xx.dtsi:	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
am4372.dtsi:	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
dra7.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2";
omap3.dtsi:	ti,hwmods = "mcbsp2", "mcbsp2_sidetone";
omap3.dtsi:	ti,hwmods = "mcbsp3", "mcbsp3_sidetone";
omap4.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
omap5.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";

That's not correct way of doing things in this case because these are
separate devices with their own address space, interrupts, SYSCONFIG
registers and can set their PM states independently.

So they should all be fixed up to be separate devices in the .dts files.

We also have the related data removed for at least omap4 in commit
3b9b1015

 (ARM: OMAP4: hwmod data: Clean up the data file), so
that data is wrongly initialized as null data.

So we need to fix two bugs:

1. We are only checking the first entry of the ti,hwmods property

   This means that we're only initializing the first hwmods entry
   instead of the ones listed in the ti,hwmods property.

2. We are only checking the child nodes, not the nodes themselves

   This means that anything listed at OCP level is currently just
   ignored and unitialized and at least the omap4 case, with the
   legacy data missing from the hwmod.

Fix both of the issues by using an index to the ti,hwmods property
and changing the hwmod lookup function to also check the current node
for ti,hwmods property instead of just the children.

While at it, let's also add some warnings for the bad data so it's
easier to fix.

Commit f6f91b0d (ARM: allow kuser helpers to be removed from the
vector page) required two pages for the vectors code.  Although the
code setting up the initial page tables was updated, the code which
allocates page tables for new processes wasn't, neither was the code
which tears down the mappings.  Fix this.

Some buses have negative offsets, which causes the DMA mask checks to
falsely fail.  Fix this by using the actual amount of memory fitted in
the system.

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.

On Device Tree boot the VDDS_DSI regulator is not linked to
the DPI device so omapfb driver probing fails with:

[    3.186035] OMAPFB: omapfb_probe
[    3.190704] omapdss DPI error: can't get VDDS_DSI regulator
[    3.196594] omapfb omapfb: failed to connect default display
[    3.202667] omapfb omapfb: failed to init overlay connections

[    3.212493] OMAPFB: free all fbmem
[    3.216735] omapfb omapfb: failed to setup omapfb

As a workaround name the VPLL2 regulator from twl4030 as vdds_dsi
so getting the VDDS_DSI regulator will succeed on dpi_init_regulator().

Most of the boards are using the TI AM/DM37x processor, there is only a small
quantity of IGEP Processor Boards based on TI OMAP3530. So it's better use the
omap36xx.dtsi include instead of omap34xx.dtsi include. We can add support
for the 34xx based variant later on as needed.

To avoid confusion we have added to the model the (TI AM/DM37x) comment.

IGEP's DVI connector's DDC pins are connected to OMAP's third i2c bus.

When booting with Device Trees the requested bus number is set to -1
which means that the bus number should be dynamically assigned. So the
third i2c bus has 2 has a bus number.

Since now only DT booting is supported for IGEP boards after commit
06ff74fd

 ("ARM: OMAP2+: remove legacy support for IGEP boards"), the
i2c bus number has to be changed.
