ARM: dts: ux500: configure the accelerometers open drain
Configure the two accelerometers sharing GPIO line 82 as:
- Open drain so that they can share the same interrupt line.
Configure the corresponding interrupt pin:
- Trigger on the falling edge since open drain implies that we
do not actively drive the line high, but we will actively drive
it low to generate interrupts and then it moves from high to low
i.e. a falling edge.
- Pulled up so the line will be biased to high unless an IRQ
is active on any device on the line, and thus it goes high
again after the interrupt is deasserted.

ARM: dts: dra7x: Remove QSPI pinmux
DRA7 family of processors from Texas Instruments, have a hardware module
called IODELAYCONFIG Module which is expected to be configured. This
block allows very specific custom fine tuning for electrical
characteristics of IO pins that are necessary for functionality and
device lifetime requirements. IODelay module has it's own register space
with registers to configure various pins.
According to AM572x TRM SPRUHZ6E October 2014–Revised January 2016[1]
section 18.4.6.1 Pad Configuration, in addition to pinmuxing(MUXMODE),
when operating a pad in certain mode, Virtual/Manual IO Timing Mode must
also be configured to ensure that IO timings are met (DELAYMODE and
MODESELECT fields of pad's IODELAYCONFIG module register). According to
section 18.4.6.1.7 Isolation Requirements of above TRM, when
reprogramming MUXMODE, DELAYMODE, and MODESELECT fields, there is a
potential for a significant glitch on the corresponding IO. It is hence
recommended to do this with I/O isolation (which can only be done in
initial stages of bootloader). QSPI is one such module that requires
IODELAY configuration. So, this patch removes the pinmux for
QSPI for DRA74/DRA72 EVM as it needs to be done in bootloader (U-Boot)
and cannot be done in kernel.
Users should migrate to U-Boot v2016.05-rc1 or higher.
ARM: dts: AM57xx/DRA7: Update SoC voltage rail limits to match data sheet
As per the data sheet starting from SPRUHQ0H (Nov 2015 - Latest[1]),
VDD_CORE can vary from 0.85v to 1.15v for AVS class0. VDD GPU/DSP
et.al. can range from 0.85v to 1.25V with AVS class0
Since dynamic voltage scaling is disabled for DRA7/AM57xx SoCs for
all SoC rails other than MPU, the bootloader is responsible for
setting up the AVS class0 voltage, however, with wrong voltage machine
constraints in dtb, regulator framework will lower the voltage below
the required voltage levels for certain samples in production flow.
This can cause catastrophic failures which can be pretty hard to
identify.
Update board files which don't match required specification.

You'll notice that the voltage cell is populated with 0's. Voltage
information is very platform specific, even depends on 'cut' and
'substrate' versions. Thus it is left blank for a generic (safe)
implementation. If other nodes/properties are provided by the
bootloader, the ST CPUFreq driver will over-ride these generic
values.

ARM: dts: imx6: fix dtc warnings for ipu endpoints
When compiled with "W=1", dtc complains: e.g.
"Warning (unit_address_vs_reg):
Node /soc/ipu@02800000/port@2/endpoint@0
has a unit name, but no reg property"
Endpoint nodes don't have a reg property, and the addresses
in their node names are ordinals without any special meaning
so remove them and swap them for semantic node names.
Add entries for VDD_ARM_CAP and VDD_SOC_CAP voltages for 198MHz according
to the imx6sx datahseet:
http://cache.nxp.com/files/32bit/doc/data_sheet/IMX6SXIEC.pdf
(a 25mV offset is added to the minimum allowed values for safety).
These values also match the ones from the NXP kernel.

Table-11 from MX6UL datasheet:
