ARM: mvebu: dt: add missing alias 'eth3' on Armada XP mv78260

It was correctly set on mv78460 but not on mv78260, resulting in my
OpenBlocks AX3-4 retrieving only 3 of its 4 MAC addresses from the
boot loader.

irqchip: orion: clear bridge cause register on init

It is good practice to mask and clear pending irqs on init. We already
mask all irqs, so also clear the bridge irq cause register.

irqchip: orion: use handle_edge_irq on bridge irqs

Bridge irqs are edge-triggered, i.e. they get asserted on low-to-high
transitions and not on the level of the downstream interrupt line.
This replaces handle_level_irq by the more appropriate handle_edge_irq.

irqchip: orion: clear stale interrupts in irq_startup

Bridge IRQ_CAUSE bits are asserted regardless of the corresponding bit in
IRQ_MASK register. To avoid interrupt events on stale irqs, we have to clear
them before unmask. This installs an .irq_startup callback to ensure stale
irqs are cleared before initial unmask.

ARM: pxa: Add dummy backlight power supply on Mitac Mio A701

Recent changes to the pwm-backlight driver have made the power supply
mandatory. There is code in the regulator core to deal with situations
where no regulator is specified and provide a dummy, but that works on
DT-based boards only.

The situation can be remedied by adding a dummy regulator during board
initialization.

regulator: da9063: Bug fix when setting max voltage on LDOs 5-11

Bug fix to allow the setting of maximum voltage for certain LDOs.

What the bug is:

There is a problem caused by an invalid calculation of n_voltages
in the driver. This n_voltages value has the potential to be
different for each regulator.

The value for linear_min_sel is set as DA9063_V##regl_name#
which can be different depending upon the regulator. This is
chosen according to the following definitions in the DA9063
registers.h file:

DA9063_VLDO1_BIAS	0
DA9063_VLDO2_BIAS	0
DA9063_VLDO3_BIAS	0
DA9063_VLDO4_BIAS	0
DA9063_VLDO5_BIAS	2
DA9063_VLDO6_BIAS	2
DA9063_VLDO7_BIAS	2
DA9063_VLDO8_BIAS	2
DA9063_VLDO9_BIAS	3
DA9063_VLDO10_BIAS	2
DA9063_VLDO11_BIAS	2

The calculation for n_voltages is valid for LDOs whose BIAS value
is zero but this is not correct for those LDOs which have a
non-zero value.

What the fix is:

In order to take into account the non-zero linear_min_sel value which
is set for the regulators LDO5, LDO6, LDO7, LDO8, LDO9, LDO10 and
LDO11, the calculation for n_voltages should take into account the
missing term defined by DA9063_V##regl_name#.

This will in turn allow the core constraints calculation to set the
maximum voltage limits correctly and therefore allow users to apply
the maximum expected voltage to all of the LDOs.

       ARM: OMAP: gpmc: add DT bindings for GPMC timings and NAND

OMAP SoC(s) depend on GPMC controller driver to parse GPMC DT child nodes and
register them platform_device for NAND driver to probe later. However this does
not happen if generic MTD_NAND framework is built as module (CONFIG_MTD_NAND=m).

Therefore, when MTD/NAND and MTD/NAND/OMAP2 modules are loaded, they are unable
to find any matching platform_device and remain un-binded. This causes on board
NAND flash to remain un-detected.

This patch causes GPMC controller to parse DT nodes when
CONFIG_MTD_NAND=y || CONFIG_MTD_NAND=m
