Headphone/mic jack detection doesn't work on the Chromebook Pixel 2015.
This patch changes the irq implementation to support polarity flipping
and fixes the configuration code so that correct GPIO pins are read
from ACPI.
With this series, plugging and unplugging the headphone jack switches

The rt5677 driver uses ACPI-style property names to read from the
device API. However, these do not match the property names in _DSD

style. Unify the two functions for reading from the device API so that
they try ACPI-style nam
This patch moves the code to select the gpios for jack detection
from rt5677_probe to rt5677_init_irq (called from rt5677_i2c_probe).
It also sets some registers to fix bugs related to jack detection, and
adds some constants and comments to make it easier to understand what

From: Ben Zhang
The rt5677 driver writes to the IRQ control register within the IRQ
handler in order to flip the polarity of the interrupts that have been
signalled. If an interrupt fires in the interval between the
regmap_read and the regmap_write, it will not trigger a new call to
rt5677_irq.
From: Ben Zhang
The rt5677 jack detection function has a requirement that the polarity
of an interrupt be flipped after it fires in order to clear the
interrupt.
This patch implements an irq_chip with irq_domain directly instead of
using regmap-irq, so that interrupt source line polarities can b

The comment describes why in detail. This was found because QEMU never
gives up load reservations, the issue is unlikely to manifest on real

Many times in libsas, and in LLDDs which use libsas, the check for an

Use dev_is_expander() instead. We rename this from
sas_dev_type_is_expander() to not spill so many lines in referencing.

In order to support checking for a layout lease on a FS DAX inode these
calls need to know if FOLL_LONGTERM was specified.
Prepare for this with this patch.

On FS DAX files users must inform the file system they intend to take
long term GUP pins on the file pages. Failure to do so should result in
an error.
Ensure that a F_LAYOUT lease exists at the time the GUP call is made.
If not return EPERM.

GUP longterm pins of non-pagecache file system pages (eg FS DAX) are
currently disallowed because they are unsafe.
The danger for pinning these pages comes from the fact that hole punch
