ACPI device enumeration mechanism changed a lot since 3.16-rc1.
ACPI device objects with _HID will be enumerated to platform bus by default.
For the existing PNP drivers that probe the PNPACPI devices, the device ids
are listed explicitly in drivers/acpi/acpi_pnp.c.
But ACPI folks will continue their effort on shrinking this id list by
converting the PNP drivers to platform drivers, for the devices that don't
belong to PNP bus in nature.

Palmas power button just needs threaded IRQ handler since I2C operations

do.

So mark the request with ONESHOT as it should have been done in these

Many palmas family of PMICs have support for interrupt based power button.
This allows the device to notify the processor of external push button
events over the shared palmas interrupt. However, this event is generated
only during a "press" operation. Software is supposed to poll(sigh!) for
detecting a release event.

The PMIC also supports ability to power off independent of the software
decisions when the button is pressed for a long duration if the PMIC is
appropriately configured on the platform.

Even though the function is similar to twl4030_pwrbutton, it is
substantially different in operation to belong to a new driver of it's own.

Adding support for the DRV2667 haptic driver.  This device has the ability
to store vibration patterns in RAM and execute them once the GO bit is set.

The initial driver sets a basic waveform in the first waveform sequence and
will play the waveform when the GO bit is set and will continously play the
waveform until the GO bit is unset.

force feedback to produce a wave form to driver an ERM or LRA actuator
device.

The initial driver supports the devices real time playback mode.  But the

The memory are mapped using of_ioremap() which is
an indication this is sbus memory.
Shift all uses of inb/outb to the sbus variants.

The inb/outb methods uses ASI_PHYS_BYPASS_EC_E_L,
whereas sbus_ variants uses ASI_PHYS_BYPASS_EC_E.

The difference is if the reads/writes are done in
native or little endian.
But for byte reads/writes there is no difference
so this does not matter for inb/outb - and this
driver only uses the byte variants.

Using platform_get_irq_byname() to retrieve the IRQ number returns the
VIRQ number rather than the local IRQ number for the device.  Passing that
value then into regmap_irq_get_virq() causes a failure because the
function is expecting the local IRQ number (e.g.  0, 1, 2, 3, etc).

This patch removes use of regmap_irq_get_virq() to prevent this failure
from happening.
