The Olimex A20-SOM-EVB is an evaluation board for the Olimex
A20-SOM system-on-module. It provides a set of android-style
buttons (labeled "VOL+", "VOL-", "MENU", "SEARCH", "HOME", "ESC"
and "ENTER") which are connected to a low-resolution ADC via a
resistor network.
This patch adds appropriate button definitions to the board
dts. The voltages assigned to the keys are specified in the
board schematics published by the manufacturer.

The way the mode probing works is this:
1. All modes currently on the mode list are marked as UNVERIFIED
2. New modes are on the probed_modes list (they start with
status OK)
3. Modes are moved from the probed_modes list to the actual
mode list. If a mode already on the mode list is deemed
to match one of the probed modes, the duplicate is dropped
and the mode status updated to OK. After this the
probed_modes list will be empty.
4. All modes on the mode list are verified to not violate any
constraints. Any that do are marked as such.
5. Any mode left with a non-OK status is pruned from the list,
with an appropriate debug message.
What all this means is that any mode on the original list that
didn't have a duplicate on the probed_modes list, should be left
with status UNVERFIED (or previously could have been left with
some other status, but never OK).
I broke that in
commit 05acaec334 ("drm: Reorganize probed mode validation")
by always assigning something to the mode->status during the validation
step. So any mode from the old list that still passed the validation
would be left on the list with status OK in the end.
Fix this by not doing the basic mode validation unless the mode
already has status OK (meaning it came from the probed_modes list,
or at least a duplicate of it was on that list). This way we will
correctly prune away any mode from the old mode list that didn't
appear on the probed_modes list.

The pvclock vdso code was too abstracted to understand easily
and excessively paranoid. Simplify it for a huge speedup.
This opens the door for additional simplifications, as the vdso
no longer accesses the pvti for any vcpu other than vcpu 0.
Before, vclock_gettime using kvm-clock took about 45ns on my
machine. With this change, it takes 29ns, which is almost as
fast as the pure TSC implementation.

Bit 7 of the "Header Type" register indicates a multi-function device when
set. Bits 0-6 contain encoded values, where 0x1 indicates a PCI-PCI
bridge. It is incorrect to test this as though it were a mask.
For example, while the PCI 3.0 spec only defines values 0x0, 0x1, and 0x2,
it's conceivable that a future spec could define 0x3 to mean something
else; then tests for "(hdr_type & 0x7f) & PCI_HEADER_TYPE_BRIDGE" would
incorrectly succeed for this new 0x3 header type.
Test bits 0-6 of the Header Type for equality with PCI_HEADER_TYPE_BRIDGE.

Merge tag 'omap-for-v4.4/fixes-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Merge "omap fixes against v4.4-rc4" from Tony Lindgren
Few fixes for omaps for v4.4-rc cycle:
- Fix clock source for ARM TWD and global timers on am437x
- Always select REGULATOR_FIXED_VOLTAGE for omap2+ instead of
when MACH_OMAP3_PANDORA is selected
- Fix SPI DMA handles for dm816x as only some were mapped
- Fix up mbox cells for dm816x to make mailbox usable
* tag 'omap-for-v4.4/fixes-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: dts: am4372: fix clock source for arm twd and global timers
ARM: OMAP2+: enable REGULATOR_FIXED_VOLTAGE
ARM: dts: add dm816x missing spi DT dma handles
ARM: dts: add dm816x missing #mbox-cells
The recent change to use a pwm lookup table for the ezx machines
was incomplete and only changed the a780 model, but not the
other ones in the same file.
This adds the missing calls to pwm_add_table().

- fix of a hardware setup that prevents the sd/mmc interface to show up on
sama5d2.
- proper selection of pinctrl drivers. PIO4 is necessary for the sama5d2 to
boot.

The alignment constraint isn't necessary now that devm_memremap_pages()

Some drivers require a way to translate GPIO pins to their IRQ numbers.
This patch adds the .to_irq() gpiolib callback to the pinctrl-xway
driver, which returns an IRQ mapping for a given GPIO pin.

Most are minor to important fixes. There is one performance enhancement
that I took on the grounds that failing to check if other processes can
run before running what's intended to be a background, idle-time task
is a bug, even though the primary effect of the fix is to improve
performance (and it was a very simple patch).

OPP bindings (for few properties) allow a platform to choose a
value/range among a set of available options. The options are present as
opp-<prop>-<name>, where the platform needs to supply the <name> string.
The OPP properties which allow such an option are: opp-microvolt and
opp-microamp.
Add support to the OPP-core to parse these bindings, by introducing
dev_pm_opp_{set|put}_prop_name() APIs.
