The Technexion TAO3530 is a OMAP3530 based SOM. This patch adds the
basic support for it as an dtsi file which can be included by
baseboard equipped with this SOM. E.g. the Technexion Thunder
baseboard.

DRA72x-evm uses TPS65917 PMIC. Add the node.

NOTE: LDO2 is actually unused, but the usage if any is expected to be
between 1.8 to 3.3v IO voltage. So define the node.

NOTE: Interrupt used is crossbar number based.

Commit 43fef47f (mfd: twl4030-power: Add a configuration to turn
off oscillator during off-idle) added support for configuring the PMIC
to cut off resources during deeper idle states to save power.

This however caused regression for n900 display power that needed the
PMIC configuration to be disabled with commit d937678a (ARM: dts:
Revert enabling of twl configuration for n900).

Turns out the root cause of the problem is that we must use
TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling
regulators that may have been enabled before the init function
for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the
regulator framework control the regulators like it should. Here we
need to only configure the sys_clken and sys_off_mode triggers for
the regulators that cannot be done by the regulator framework as
it's not running at that point.

This allows us to enable the PMIC configuration for n900.

This patch is important for the MicroSOM implementation due to the
following details -

1. VIH of the Atheros phy is 1.7V.
2. NVCC_ENET which is the power domain of the MDIO pad is driven by the
   PHY's LDO (i.e. either 1.8v or 2.5v).
3. The MicroSOM implements an onbouard 1.6kohm pull up to 3.3v (R3000).

In the case the PHY's LDO was 1.8v then there would be only a 100mV
margin for the signal to be acknowledged as high (1.8v-1.7v).
Due to that setting the pad as an open drain will let the 1.6kohm pull
that signal high to 3.3 that assures enough margins to the PHY to be
acked as '1' logic.

GPIO modules are also interrupt sources. However, they require both the
GPIO number and IRQ type to function properly.

By declaring that GPIO uses interrupt-cells=<1>, we essentially do not
allow users of the nodes to use the interrupt property appropritely.

With this change, the following now works:

interrupt-parent = <&gpio6>;
interrupts = <5 IRQ_TYPE_LEVEL_LOW>;

For v3.14 and prior, 1-bit Hamming code ECC via software was used
for NAND on this board.
Commit c06c5270 in v3.15 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.

This ECC layout change causes NAND filesystems created in v3.14
and prior to be unusable in v3.15 and later. So revert back to
using software ECC scheme.

Working on Gigabit/PCIe support in U-Boot for Apalis T30 I realised
that the current device tree source includes for our modules only
happen to work due to referencing the on-carrier 5v0 supply from USB
which is not at all available on-module. The modules actually contain
TPS60150 charge pumps to generate the PMIC required 5 volts from the
one and only 3.3 volt module supply. This patch fixes this.

(Note: When back-porting this to v3.16 stable releases, simply drop the
change to tegra30-apalis.dtsi; that file was added in v3.17)

Increase max i2c bus frequency beyond the default for faster
data transfers. According to the manual, these faster speeds are
only available when the board is wired up the right way. In this case,
the vendor kernel has run at this speed for a long time.

sda-delay is needed for talking to RTC on PMIC, otherwise the i2c
controller never sees an ACK. Strangely the other PMIC i2c slave (the
main one) works fine even without this delay. I Chose value 100 to
match the vendor kernel.

The GPIO pin connected to card detect was inverted twice: once by
the argument to the GPIO line itself where it was magically marked
as active low by the flag GPIO_ACTIVE_LOW (0x01) in the third cell,
and also marked active low AGAIN by explicitly stating
"cd-inverted" (a deprecated method).

After commit 78f87df2
"mmc: mmci: Use the common mmc DT parser" this results in the
line being inverted twice so it was effectively uninverted, while
the old code would not have this effect, instead disregarding the
flag on the GPIO line altogether, which is a bug. I admit the
semantics may be unclear but inverting twice is as good a
definition as any on how this should work.

So fix up the buggy device tree. Use proper #includes so the DTS
is clear and readable.
