Merge branch 'acpi-soc'
* acpi-soc:
PM / clk: don't leave clocks enabled when driver not bound
i2c: dw: Add APM X-Gene ACPI I2C device support
ACPI / APD: Add APM X-Gene ACPI I2C device support
ACPI / LPSS: change 'does not have' to 'has' in comment
Revert "dmaengine: dw: platform: provide platform data for Intel"
dmaengine: dw: return immediately from IRQ when DMA isn't in use
dmaengine: dw: platform: power on device on shutdown
ACPI / LPSS: override power state for LPSS DMA device
ACPI / LPSS: power on when probe() and otherwise when remove()
ACPI / LPSS: do delay for all LPSS devices when D3->D0
ACPI / LPSS: allow to use specific PM domain during ->probe()
Revert "ACPI / LPSS: allow to use specific PM domain during ->probe()"
device core: add BUS_NOTIFY_DRIVER_NOT_BOUND notification
x86/platform/iosf_mbi: Remove duplicate definitions
